Reliable Identification Of Binary Supermassive Black Holes From Rubin Observatory Time-Domain Monitoring, Megan C. Davis, Kaylee E. Grace, Jonathan R. Trump, Jessie C. Runnoe, Amelia Henkel, Laura Blecha, W N. Brandt, J Andrew Casey-Clyde, Maria Charisi, Caitlin A. Witt

Faculty Publications

Periodic signatures in time-domain observations of quasars have been used to search for binary supermassive black holes (SMBHs). These searches, across existing time-domain surveys, have produced several hundred candidates. The general stochastic variability of quasars, however, can masquerade as a false-positive periodic signal, especially when monitoring cadence and duration are limited. In this work, we predict the detectability of binary SMBHs in the upcoming Rubin Observatory Legacy Survey of Space and Time (LSST). We apply computationally inexpensive sinusoidal curve fits to millions of simulated LSST Deep Drilling Field light curves of both single, isolated quasars and binary quasars. The period …

Universal Design For Learning (Udl)- Strategies For Engaging Rural Youth Co-Researchers With Informal Stem Learning, Amanda Bastoni, Jayson Seaman, Andrew D. Coppens, Cindy Hartman, Kate Moscouver, Courtnie Lachaine

Faculty Publications

This article describes methods and findings from a study focused on youth living in rural communities in northern New Hampshire who struggle with accessing STEM learning opportunities for reasons including economic underinvestment and geographical isolation. These challenges also negatively impact researchers hoping to learn how rural youth benefit from informal STEM learning experiences, which contribute to low-project participation and retention rates. As in other amenity-rich rural areas, the communities in this study are promoting outdoor recreation as a vehicle for economic development. We wanted to understand if outdoor recreation activities tied to economic growth initiatives — activities which youth have …

Soil Incubation Methods Lead To Large Differences In Inferred Methane Production Temperature Sensitivity, Zhen Li, Robert F. Grant, Kuang-Yu Chang, Suzanne B. Hodgkins, Jinyun Tang, Alexandra Cory, Zelalem A. Mekonnen, Scott R. Saleska, Eoin L. Brodie, Ruth K. Varner, Virginia I. Rich, Rachel M. Wilson, Jeff P. Chanton, Patrick Crill, William J. Riley

Quantifying the temperature sensitivity of methane (CH4) production is crucial for predicting how wetland ecosystems will respond to climate warming. Typically, the temperature sensitivity (often quantified as a Q10 value) is derived from laboratory incubation studies and then used in biogeochemical models. However, studies report wide variation in incubation-inferred Q10 values, with a large portion of this variation remaining unexplained. Here we applied observations in a thawing permafrost peatland (Stordalen Mire) and a well-tested process-rich model (ecosys) to interpret incubation observations and investigate controls on inferred CH4 production temperature sensitivity. We developed a field-storage-incubation modeling approach to mimic the full …

A Case Study Of Us National Debt: 2008–2018, Drew Dickinson

Inquiry Journal Spring 2024

National debt in the United States has the potential to impact every citizen and resident of the nation, due to increased taxes on a federal level or downstream impacts on programs provided by the government. Some of this debt is held internally—meaning by entities within the United States, such as the Social Security Administration. Foreign or external debt, on the other hand, is debt held by an entity, like a nation, that is outside the United States.

Through a capstone-level political science course, I researched the impacts of externally versus internally held debt on the United States’ overall indebtedness, using …

Parker Solar Probe (PSP) observations of a small dispersive event on 2022 February 27 and 28 indicate scatter-free propagation as the dominant transport mechanism between the low corona and greater than 35 solar radii. The event occurred during unique orbital conditions that prevailed along specific flux tubes that PSP encountered repeatedly between 25 and 35 Rs during outbound orbit 11. This segment of the PSP orbit exhibits almost stationary angular motion relative to the rotating solar surface, such that in the rotating frame, PSP’s motion is essentially radial. The time dispersion often observed in impulsive solar energetic particle (SEP) events …

On The Origin Of The Sudden Heliospheric Open Magnetic Flux Enhancement During The 2014 Pole Reversal, Stephan G. Heinemann, Mathew J. Owens, Manuela Temmer, James A. Turtle, Charles N. Arge, Carl J.

Coronal holes are recognized as the primary sources of heliospheric open magnetic flux (OMF). However, a noticeable gap exists between in situ measured OMF and that derived from remote-sensing observations of the Sun. In this study, we investigate the OMF evolution and its connection to solar structures throughout 2014, with special emphasis on the period from September to October, where a sudden and significant OMF increase was reported. By deriving the OMF evolution at 1 au, modeling it at the source surface, and analyzing solar photospheric data, we provide a comprehensive analysis of the observed phenomenon. First, we establish a …

Pyramid Model Family Engagement Survey Results​ ​, George Tremblay, Pyramid Model Consortium

New Hampshire Early Care and Education Research Consortium

The Pyramid Model State Leadership Team Data and Evaluation Workgroup developed a Family Engagement Survey to collect data that it hoped would inform the State’s and individual programs’ improvement efforts. In March 2024, the Family Engagement Survey was emailed to 40 NH child care programs on the Granite Steps for Quality Pyramid Model Pathway. These Program Directors were asked to share the survey with families.

Factors Affecting Iodine Content Of Cow Milk-A Review, Mmh Khandakar, Ma Islam

Faculty Publications

This review discusses the importance of iodine as an essential nutrient for human health and the factors that can influence the concentration of iodine in cow milk. For an adult, the daily recommended requirement of iodine is 150 µg/day and the maximum tolerable limit ranges from 600 to 1100 µg/day. Cow milk is a significant source of iodine in many countries, particularly in areas where iodine-rich foods are not readily available. Therefore, evaluating the variables that affect the iodine content of cow milk is important. The iodine concentration of cow milk can vary depending on several factors such as genetics, …

Identifying how animals select habitat while navigating landscapes is important for understanding behavioral ecology and guiding management and conservation decisions. However, habitat selection may be spatially and temporally plastic, making it challenging to quantify how species use resources across space and time.

Natural Warming Differentiates Communities And Increases Diversity In Deep-Sea Ridge Flank Hydrothermal Systems, Anne M. Hartwell, Anna E. Wheat, Jennifer A. Dijkstra

Center for Coastal and Ocean Mapping

Ridge Flank Hydrothermal Systems have discrete pockets of fluid discharge that mimic climate-induced ocean warming. Unlike traditional hydrothermal fluids, those discharged by Ridge Flank Hydrothermal Systems have a chemical composition indistinguishable from background water, enabling evaluation of the effect of warming temperature. Here we link temperature and terrain variables to community composition and biodiversity by combining remotely operated vehicle images of vent and non-vent zone communities with associated environmental variables. We show overall differences in composition, family richness, and biodiversity between zones, though richness and diversity were only significantly greater in vent zones at one location. Temperature was a contributing …

Design, Deployment, And Operation Of An Experimental Offshore Seaweed Cultivation Structure, Zachary Moscicki, M Robinson Swift, Tobias Dewhurst, Michael Macnicoll, Michael Chambers, Igor Tsukrov, David W. Fredriksson, Peter Lynn, Melissa E. Landon, Beth Zotter, Noah Macadam

Faculty Publications

Seaweed cultivation systems suitable for offshore and exposed locations have the potential to enable expansion of global seaweed production to levels capable of substantially supplementing or offsetting terrestrial agriculture. A demonstration scale, experimental seaweed cultivation system (farm) intended to withstand exposed ocean environments was designed, deployed, planted with kelp (a type of seaweed), monitored and decommissioned. Objectives for the field program included: [1] observation of the farm's behavior and survivability in exposed ocean conditions, [2] demonstration of novel farm system design features and component technologies, and [3] evaluation of farm operability. Novel design features included a lattice mooring system geometry, …
