Search For Long-Duration Gravitational-Wave Signals Associated With Magnetar Giant Flares, A Macquet, M A. Bizouard, E Burns, N Christensen, A Macquet, Z Wadiasingh, G Younes

Faculty Publications

Magnetar giant flares are rare and highly energetic phenomena observed in the transient sky whose emission mechanisms are still not fully understood. Depending on the nature of the excited modes of the magnetar, they are also expected to emit gravitational waves (GWs), which may bring unique information about the dynamics of the excitation. A few magnetar giant flares have been proposed to be associated with short gamma-ray bursts. In this paper we use a new gravitational-wave search algorithm to revisit the possible emission of GWs from four magnetar giant flares within 5 Mpc. While no gravitational-wave signals were observed, we …

Anomalies In The Cosmic Microwave Background And Their Non-Gaussian Origin In Loop Quantum Cosmology, I Agullo, D Kranas, V Sreenath

Faculty Publications

Anomalies in the cosmic microwave background (CMB) refer to features that have been observed, mostly at large angular scales, and which show some tension with the statistical predictions of the standard ?CDM model. In this work, we focus our attention on power suppression, dipolar modulation, a preference for odd parity, and the tension in the lensing parameter A ( L ). Though the statistical significance of each individual anomaly is inconclusive, collectively they are significant, and could indicate new physics beyond the ?CDM model. In this article, we present a brief, but pedagogical introduction to CMB anomalies and propose a …

The most common way to discover extragalactic fast transients, which fade within a few nights in the optical, is via follow-up of gamma-ray burst and gravitational-wave triggers. However, wide-field surveys have the potential to identify rapidly fading transients independently of such external triggers. The volumetric survey speed of the Zwicky Transient Facility (ZTF) makes it sensitive to objects as faint and fast fading as kilonovae, the optical counterparts to binary neutron star mergers, out to almost 200 Mpc. We introduce an open-source software infrastructure, the ZTF REaltime Search and Triggering, ZTFReST, designed to identify kilonovae and fast transients in ZTF …

The observation of gravitational waves is hindered by the presence of transient noise (glitches). We study data from the third observing run of the Advanced LIGO detectors, and identify new glitch classes: fast scattering/crown and low-frequency blips. Using training sets assembled by monitoring of the state of the detector, and by citizen-science volunteers, we update the Gravity Spy machine-learning algorithm for glitch classification. We find that fast scattering/crown, linked to ground motion at the detector sites, is especially prevalent, and identify two subclasses linked to different types of ground motion. Reclassification of data based on the updated model finds that …

The Effectiveness Of Image Augmentation In Deep Learning Networks For Detecting Covid-19: A Geometric Transformation Perspective, M Elgendi, M U. Nasir, Q F. Tang, D Smith, M Elgendi, C Batte, B Spieler, W D. Leslie, C Menon, R R. Fletcher, N Howard, R Ward, W Parker, S Nicolaou

Faculty Publications

Chest X-ray imaging technology used for the early detection and screening of COVID-19 pneumonia is both accessible worldwide and affordable compared to other non-invasive technologies. Additionally, deep learning methods have recently shown remarkable results in detecting COVID-19 on chest X-rays, making it a promising screening technology for COVID-19. Deep learning relies on a large amount of data to avoid overfitting. While overfitting can result in perfect modeling on the original training dataset, on a new testing dataset it can fail to achieve high accuracy. In the image processing field, an image augmentation step (i.e., adding more training data) is often …

Here we present new, yet final, mid-infrared (mid-IR) data for supernovae (SNe) based on measurements with the Spitzer Space Telescope. Comparing our recent 3.6 and 4.5 mu m photometry with previously published mid-IR and further multiwavelength data sets, we were able to draw some conclusions about the origin and heating mechanism of the dust in these SNe or in their environments, as well as about possible connection with circumstellar matter (CSM) originating from pre-explosion mass-loss events in the progenitor stars. We also present new results regarding both certain SN classes and single objects. We highlight the mid-IR homogeneity of SNe …

We report on an all-sky search for continuous gravitational waves in the frequency band 20-2000 Hz and with a frequency time derivative in the range of [-1.0; +0.1] x 10(-8) Hz/s. Such a signal could be produced by a nearby, spinning and slightly nonaxisymmetric isolated neutron star in our Galaxy. This search uses the LIGO data from the first six months of Advanced LIGO's and Advanced Virgo's third observational run, O3. No periodic gravitational wave signals are observed, and 95% confidence-level (C.L.) frequentist upper limits are placed on their strengths. The lowest upper limits on worst-case (linearly polarized) strain amplitude …

Kepler K2 Campaign 9-I. Candidate Short-Duration Events From The First Space-Based Survey For Planetary Microlensing, I Mcdonald, E Kerins, R Poleski, M T. Penny, I Mcdonald, S Mao, P Fouque, W Zhu, W Zang

Faculty Publications

We present the first short-duration candidate microlensing events from the Kepler K2 mission. From late April to early July 2016, Campaign 9 of K2 obtained high temporal cadence observations over a 3.7 deg(2) region of the Galactic bulge. Its primary objectives were to look for evidence of a free-floating planet (FFP) population using microlensing, and demonstrate the feasibility of space-based planetary microlensing surveys. Though Kepler K2 is far from optimal for microlensing, the recently developed MCPM photometric pipeline enables us to identify and model microlensing events. We describe our blind event-selection pipeline in detail and use it to recover 22 …

Kepler revealed that roughly one-third of Sunlike stars host planets orbiting within 100 days and between the size of Earth and Neptune. How do these planets form, what are they made of, and do they represent a continuous population or multiple populations? To help address these questions, we began the Magellan-TESS Survey (MTS), which uses Magellan II/PFS to obtain radial velocity (RV) masses of 30 TESS-detected exoplanets and develops an analysis framework that connects observed planet distributions to underlying populations. In the past, small-planet RV measurements have been challenging to obtain due to host star faintness and low RV semiamplitudes …

Role Of Dissipative Effects In The Quantum Gravitational Onset Of Warm Starobinsky Inflation In A Closed Universe

Faculty Publications

A problematic feature of low-energy-scale inflationary models, such as Starobinsky inflation, in a spatially closed universe is the occurrence of a recollapse and a big crunch singularity before inflation can even set in. In a recent work, it was shown that this problem can be successfully resolved in loop quantum cosmology for a large class of initial conditions due to a nonsingular cyclic evolution and a hysteresislike phenomenon. However, for certain highly unfavorable initial conditions, the onset of inflation was still difficult to obtain. In this work, we explore the role of dissipative particle production, which is typical in warm …

Everything You Wanted To Know About Space Radiation But Were Afraid To Ask, Jeffery Chancellor, Craig Nowadly, Jacqueline Williams, Serena Aunon-Chancellor, Megan Chesal, Jayme Looper, Wayne Newhauser

Faculty Publications

The space radiation environment is a complex combination of fast-moving ions derived from all atomic species found in the periodic table. The energy spectrum of each ion species varies widely but is prominently in the range of 400–600 MeV/n. The large dynamic range in ion energy is difficult to simulate in ground-based radiobiology experiments. Most ground-based irradiations with mono-energetic beams of a single one ion species are delivered at comparatively high dose rates. In some cases, sequences of such beams are delivered with various ion species and energies to crudely approximate the complex space radiation environment. This approximation may cause …

Host Genotype And Tissue Type Determine Dwv Infection Intensity, Hannah J. Penn, Michael Simone-Finstrom, Sarah Lang, Judy Chen, Kristen Healy

Faculty Publications

Varroa mite-vectored viruses such as Deformed wing virus (DWV) are of great concern for honey bee health as they can cause disease in individuals and increase colony mortality. Two genotypes of DWV (A and B) are prevalent in the United States and may have differential virulence and pathogenicity. Honey bee genetic stocks bred to resist Varroa mites also exhibit differential infection responses to the Varroa mite-vectored viruses. The goal of this project was to determine if interactions between host genotype could influence the overall infection levels and dissemination of DWV within honey bees. To do this, we injected DWV isolated …

An Assessment Of The Relationship Between Sweetener Prices And High Fructose Corn Syrup Deliveries In The United States, P. Lynn Kennedy, Pablo A. Garcia-Fuentes, Gustavo F.C. Ferreira

Faculty Publications

This paper uses an application of the Bertrand model to explain the relationship between HFCS deliveries and the prices of HFCS-42 and sugar. It finds that the HFCS deliveries and the prices of HFCS-42 and refined sugar are cointegrated over the period 1994:q1-2020:q1. The main results, based on the estimated long-run elasticities, show that a one percent increase in the price of HFCS-42 decreases HFCS deliveries by 0.153 percent. One implication of this result is that it would be helpful for the HFCS industry to prevent large increases in the HFCS price, which would prevent large decreases in HFCS deliveries …

Kentucky Soybean Farmers' Supportiveness Of Two Integrated Pest And Pollinator Management Tactics, Hannah J. Penn, Jerrod Penn, Michael Cunningham-Minnick, Wuyang Hu

Faculty Publications

Beneficial insect conservation in agriculture is often studied in the context of integrated pest management (IPM). For instance, vegetative field edges provide habitat and changing the timing of insecticidal sprays decreases risk for pollinators and natural enemies of insect pests. However, the attitudes and confidence of U.S. growers towards IPM implementation in traditional row crops remain understudied. We developed an online survey using a convenience sample and surveyed Kentucky soybean growers to understand their current pest and general management practices, beliefs about sources of insect pests/weeds, and attitudes towards pollinators. We also asked about their willingness to implement two management …

On-Farm Evaluation Of Regenerative Land-Use Practices In A Semi-Arid Pasture Agroecosystem In West Texas, Usa, Lindsey Slaughter, Sanjit Deb, Somsubhra Chakraborty, Bin Li, Noura Bakr, Bryanna Edwards, David Weindorf

Faculty Publications

Continually rising scarcity in water and nutrient resources, especially in semi-arid agricultural systems, combined with increased frequency of extreme weather events such as drought, contribute to a growing need for resilient and regenerative agricultural ecosystems. However, evaluating a myriad of combinations of producer-led sustainable management practices in on-farm research remains challenging. Few studies have elucidated spatial variability in measured soil properties across the study area due to logistical and economic constraints. As such, this study aimed to: 1) establish soil health assessment and landscape variability data immediately after land-use change to a sustainable pasture management system, and 2) delineate relationships …

Weyl Sums And The Lyapunov Exponent For The Skew-Shift Schrödinger Cocycle, Rui Han, Marius Lemm, Wilhelm Schlag

Faculty Publications

We study the one-dimensional discrete Schrödinger operator with the skew-shift potential 2λ cos (2π((j/2)ω + jy C x)). This potential is long conjectured to behave like a random one, i.e., it is expected to produce Anderson localization for arbitrarily small coupling constants λ > 0. In this paper, we introduce a novel perturbative approach for studying the zero-energy Lyapunov exponent L(λ) at small λ. Our main results establish that, to second order in perturbation theory, a natural upper bound on L(λ) is fully consistent with L(λ) being positive and satisfying the usual Figotin–Pastur type asymptotics L.λ/ ~ C λ2 as λ …

Criticality In The Collapse Of Spherically Symmetric Massless Scalar Fields In Semiclassical Loop Quantum Gravity, F Benitez, R Gambini, S L. Liebling, J Pullin, F Benitez

Faculty Publications

In a recent paper we showed that the collapse to a black hole in one-parameter families of initial data for massless, minimally coupled scalar fields in spherically symmetric semiclassical loop quantum gravity exhibited a universal mass scaling similar to the one in classical general relativity. In particular, no evidence of a mass gap appeared as had been suggested by previous studies. The lack of a mass gap indicated the possible existence of a self-similar critical solution as in general relativity. Here we provide further evidence for its existence. Using an adaptive mesh refinement code, we show that echoes arise as …

Relating Dust Reference Models To Conventional Systems In Manifestly Gauge Invariant Perturbation Theory, Kristina Giesel, Bao-Fei Li, Parampreet Singh

Faculty Publications

Models with dust reference fields in relational formalism have proved useful in understanding the construction of gauge invariant perturbation theory to arbitrary orders in the canonical framework. These reference fields modify the dynamical equations for perturbation equations. However, important questions remain open on the relation with conventional perturbation theories of inflaton coupled to gravity and of multifluid systems, and on understanding modifications in terms of physical degrees of freedom. These gaps are filled in this manuscript for Brown-Kuchar and Gaussian dust models, both of which involve three scalar physical degrees of freedom. We establish a relationship of these models with …

Gamma-ray bursts (GRBs) are among the brightest and most energetic events in the Universe. The duration and hardness distribution of GRBs has two clusters(1), now understood to reflect (at least) two different progenitors(2). Short-hard GRBs (SGRBs; T-90 < 2 s) arise from compact binary mergers, and long-soft GRBs (LGRBs; T-90 > 2 s) have been attributed to the collapse of peculiar massive stars (collapsars)(3). The discovery of SN 1998bw/GRB 980425 (ref. (4)) marked the first association of an LGRB with a collapsar, and AT 2017gfo (ref. (5))/GRB 170817A/GW170817 (ref.

Core-collapse supernovae are among the most magnificent events in the observable universe. They produce many of the chemical elements necessary for life to exist and their remnants-neutron stars and black holes-are interesting astrophysical objects in their own right. However, despite millennia of observations and almost a century of astrophysical study, the explosion mechanism of core-collapse supernovae is not yet well understood. Hyper-Kamiokande is a next-generation neutrino detector that will be able to observe the neutrino flux from the next galactic core-collapse supernova in unprecedented detail. We focus on the first 500 ms of the neutrino burst, corresponding to the accretion …

We derived 16 extinction curves having a range of A(V) (1.8-5.5) and R(V) values (2.4-4.3). Our sample includes two dense sight lines that have 3 mu m ice feature detections and weak 2175 angstrom bumps. The average A(lambda)/A(V) diffuse sight-line extinction curve we …

Manipulating Phospholipid Vesicles At The Nanoscale: A Transformation From Unilamellar To Multilamellar By An N-Alkyl-Poly(Ethylene Oxide), Judith U. De Mel, Sudipta Gupta, Lutz Willner, Jürgen Allgaier, Laura R. Stingaciu, Markus Bleuel, Gerald J. Schneider

Faculty Publications

© 2021 American Chemical Society. We investigated the influence of an n-alkyl-PEO polymer on the structure and dynamics of phospholipid vesicles. Multilayer formation and about a 9% increase in the size in vesicles were observed by cryogenic transmission electron microscopy (cryo-TEM), dynamic light scattering (DLS), and small-angle neutron/X-ray scattering (SANS/SAXS). The results indicate a change in the lamellar structure of the vesicles by a partial disruption caused by polymer chains, which seems to correlate with about a 30% reduction in bending rigidity per unit bilayer, as revealed by neutron spin echo (NSE) spectroscopy. Also, a strong change in lipid tail …
