Filippenko, Ryan J. Foley, Claes Fransson, Christopher L. Gerardy, Peter A. Hoflich, Peter Lundqvist, Seppo Mattila, Jesper Sollerman, J. Craig Wheeler

Dartmouth Scholarship

We present results based on mid-infrared (3.6-30 μm) observations with the Spitzer Space Telescope of the nearby Type IIP supernova 2005af. We report the first ever detection of the SiO molecule in a Type IIP supernova. Together with the detection of the CO fundamental, this is an exciting finding as it may signal the onset of dust condensation in the ejecta. From a wealth of fine-structure lines we provide abundance estimates for stable Ni, Ar, and Ne that, via spectral synthesis, may be used to constrain nucleosynthesis models.

Application Of Coulomb Wave Function Discrete Variable Representation To Atomic Systems In Strong Laser Fields, Liang-You Peng, Anthony F. Starace Oct 2006

Application Of Coulomb Wave Function Discrete Variable Representation To Atomic Systems In Strong Laser Fields, Liang-You Peng, Anthony F. Starace

Anthony F. Starace Publications

We present an efficient and accurate grid method for solving the time-dependent Schrödinger equation for an atomic system interacting with an intense laser pulse. Instead of the usual finite difference (FD) method, the radial coordinate is discretized using the discrete variable representation (DVR) constructed from Coulomb wave functions. For an accurate description of the ionization dynamics of atomic systems, the Coulomb wave function discrete variable representation (CWDVR) method needs three to ten times fewer grid points than the FD method. The resultant grid points of the CWDVR are distributed unevenly so that one has a finer grid near the origin …

Measurements And Analysis Of Helium-Like Triplet Ratios In The X-Ray Spectra Of O-Type Stars, M. A. Leutenegger, F. B.S. Paerels, S. M. Kahn, David H. Cohen Oct 2006

Measurements And Analysis Of Helium-Like Triplet Ratios In The X-Ray Spectra Of O-Type Stars, M. A. Leutenegger, F. B.S. Paerels, S. M. Kahn, David H. Cohen

Physics & Astronomy Faculty Works

We discuss new methods of measuring and interpreting the forbidden-to-intercombination line ratios of heliumlike triplets in the X-ray spectra of O- type stars, including accounting for the spatial distribution of the X-ray-emitting plasma and using the detailed photospheric UV spectrum. Measurements are made for four O stars using archival Chandra HETGS data. We assume an X- ray-emitting plasma spatially distributed in the wind above some minimum radius R-0. We find minimum radii of formation typically in the range of 1.25 < R-0 / R-* < 1.67, which is consistent with results obtained independently from line profile fits. We find no evidence for anomalously low f / i ratios, and we do not require the existence of X-ray-emitting plasmas at radii that are too small to generate sufficiently strong shocks.

Search For Neutral, Long-Lived Particles Decaying Into Two Muons In Pp̅ Collisions At √S = 1:96 Tev, V. M. Abazov, Kenneth A. Bloom, Gregory R. Snow, D0 Collaboration Oct 2006

Search For Neutral, Long-Lived Particles Decaying Into Two Muons In Pp̅ Collisions At √S = 1:96 Tev, V. M. Abazov, Kenneth A. Bloom, Gregory R. Snow, D0 Collaboration

Kenneth Bloom Publications

We present a search for a neutral particle, pair produced in pp̅ collisions at√s = 1.96 TeV, which decays into two muons and lives long enough to travel at least 5 cm before decaying. The analysis uses ≈ 380 pb-1 of data recorded with the D0 detector. The background is estimated to be about one event. No candidates are observed, and limits are set on the pair-production cross section times branching fraction into dimuons + X for such particles. For a mass of 10 GeVand lifetime of 4 × 10-11 s, we exclude values greater than 0.14 pb …

Search For The Standard Model Higgs Boson In The Pp̅→ Zh → Νν̅Bb̅ Channel, V. M. Abazov, Kenneth A. Bloom, Gregory R. Snow, D0 Collaboration

Kenneth Bloom Publications

We report a search for the standard model (SM) Higgs boson based on data collected by the D0 experiment at the Fermilab Tevatron Collider, corresponding to an integrated luminosity of 260 pb-1. We study events with missing transverse energy and two acoplanar b jets, which provide sensitivity to the ZH production cross section in the νν̅bb̅ channel, and to WH production when the lepton from the W → ℓν decay is undetected. The data are consistent with the SM background expectation, and we set 95% C.L. upper limits on σ(pp̅ → ZH/WH) × …

A Prototype Platform For Array Feed Development, James Richard Nagel Oct 2006

A Prototype Platform For Array Feed Development, James Richard Nagel

Theses and Dissertations

Radio frequency interference (RFI) is a growing problem for radio astronomers. One potential solution utilizes spatial filtering by placing an array of electrically small antennas at the focal plane of a parabolic reflector. This thesis documents the design and characterization of a prototype array feed and RF receiver that were used to demonstrate the spatial filtering principle. The array consists of a 7-element hexagonal arrangement of thickened dipole antennas tuned to a center frequency of 1600 MHz. The receiver is a two-stage, low-noise frequency mixer that is tunable over the entire L-band. This thesis also documents a new receiver design …

Casimir Forces And Non-Newtonian Gravitation, Roberto Onofrio Oct 2006

Casimir Forces And Non-Newtonian Gravitation, Roberto Onofrio

Dartmouth Scholarship

The search for non-relativistic deviations from Newtonian gravitation can lead to new phenomena signalling the unification of gravity with the other fundamental interactions. Various recent theoretical frameworks indicate a possible window for non-Newtonian forces with gravitational coupling strength in the micrometre range. The major expected background in the same range is attributable to the Casimir force or variants of it if dielectric materials, rather than conducting ones, are considered. Here we review the measurements of the Casimir force performed so far in the micrometre range and how they determine constraints on non-Newtonian gravitation, also discussing the dominant sources of false …

The P14 Fusion-Associated Small Transmembrane (Fast) Protein Effects Membrane Fusion From A Subset Of Membrane Microdomains, Jennifer A. Corcoran, Jayme Salsman, Roberto De Antueno, Ahmed Touhami, Manfred H. Jericho, Eileen K. Clancy, Roy Duncan Oct 2006

The P14 Fusion-Associated Small Transmembrane (Fast) Protein Effects Membrane Fusion From A Subset Of Membrane Microdomains, Jennifer A. Corcoran, Jayme Salsman, Roberto De Antueno, Ahmed Touhami, Manfred H. Jericho, Eileen K. Clancy, Roy Duncan

Physics & Astronomy Faculty Publications

The reovirus fusion-associated small transmembrane (FAST) proteins are a unique family of viral membrane fusion proteins. These nonstructural viral proteins induce efficient cell-cell rather than virus-cell membrane fusion. We analyzed the lipid environment in which the reptilian reovirus p14 FAST protein resides to determine the influence of the cell membrane on the fusion activity of the FAST proteins. Topographical mapping of the surface of fusogenic p14-containing liposomes by atomic force microscopy under aqueous conditions revealed that p14 resides almost exclusively in thickened membrane microdomains. In transfected cells, p14 was found in both Lubrol WX-and Triton X-100-resistant membrane complexes. Cholesterol depletion …

Statistical Analysis Of Air Pollution Panel Studies: An Illustration, Holly Janes, Lianne Sheppard, Kristen Shepherd Oct 2006

Statistical Analysis Of Air Pollution Panel Studies: An Illustration, Holly Janes, Lianne Sheppard, Kristen Shepherd

UW Biostatistics Working Paper Series

The panel study design is commonly used to evaluate the short-term health effects of air pollution. Standard statistical methods for analyzing longitudinal data are available, but the literature reveals that the techniques are not well understood by practitioners. We illustrate these methods using data from the 1999 to 2002 Seattle panel study. Marginal, conditional, and transitional approaches for modeling longitudinal data are reviewed and contrasted with respect to their parameter interpretation and methods for accounting for correlation and dealing with missing data. We also discuss and illustrate techniques for controlling for time-dependent and time-independent confounding, and for exploring and summarizing …

The Politics Of Space And Culture In Santiago, Chile's Street Markets, Joel Stillerman Oct 2006

The Politics Of Space And Culture In Santiago, Chile's Street Markets, Joel Stillerman

Peer Reviewed Articles

Recent discussions of contentious politics have focused on struggles in and over space and place. This article builds upon these concerns by using ethnographic, interview, and documentary data to analyze the spatial politics of street market vendors in Santiago, Chile. Drawing upon Lefebvre’s concepts of perceived, conceived, and lived space as well as ideas drawn from research on space and protest, I show how street market vendors build upon spatial routines, a sense of place, political alliances, and scale jumping in their self-defense strategies at the local, national, and international scales. The findings illustrate Lefebvre’s argument that the advance of …

Remote Bond Breaking By Interacting Temporary Anion States, Paul Burrow, Gordon A. Gallup Oct 2006

Remote Bond Breaking By Interacting Temporary Anion States, Paul Burrow, Gordon A. Gallup

Gordon Gallup Publications

The cross section for bond breaking at the site of a dissociative temporary negative ion state through the dissociative electron attachment process can be considerably enhanced by the presence of a second longer-lived temporary negative ion state elsewhere in the molecule, even one quite remote from the first. In a series of chloroalkenes possessing both C–Cl and C=C bonds separated by various distances, we show that the cross sections are determined by the lifetime of the lower anion state created by the mixing of the anion states of these two moieties, with the wave function’s coefficients giving the probability that …
