New Limits on Sterile Neutrinos from Suzaku Observations of the Ursa Minor Dwarf Spheroidal Galaxy

, 2009
We present results of our search for X-ray line emission associated with the radiative decay of the sterile neutrino, a well-motivated dark matter candidate, in Suzaku Observatory spectra of the Ursa Minor dwarf spheroidal galaxy.

The Spectral Correlation Function -- A New Tool for Analyzing Spectral-Line Maps [PDF]

, 1999
The "spectral correlation function" analysis we introduce in this paper is a new tool for analyzing spectral-line data cubes. Our initial tests, carried out on a suite of observed and simulated data cubes, indicate that the spectral correlation function [

Dark Matter Subhalos in the Ursa Minor Dwarf Galaxy

, 2012
Through numerical simulations, we study the dissolution timescale of the Ursa Minor cold stellar clump, due to the combination of phase-mixing and gravitational encounters with compact dark substructures in the halo of Ursa Minor.

Rheological Characterization and Multi‐Regime Viscosity Modeling of Diluted Polyethylene Mixtures

Polymer Engineering &Science, EarlyView.
This study maps the flow behavior of low‐density polyethylene in a recycling solvent from dilute solutions to entangled melts. By integrating time–concentration and time–temperature superposition, and coupling three complementary rheometry methods, a unified semiempirical model accurately predicts steady‐shear viscosity over nine decades of viscosity ...

VERITAS Search for VHE Gamma-ray Emission from Dwarf Spheroidal Galaxies [PDF]

, 2010
Indirect dark matter searches with ground-based gamma-ray observatories provide an alternative for identifying the particle nature of dark matter that is complementary to that of direct search or accelerator production experiments. We present the results

Association between urinary polycyclic aromatic hydrocarbons and unexplained recurrent spontaneous abortion from a case-control study

Ecotoxicology and Environmental Safety
Polycyclic aromatic hydrocarbons (PAHs) have been reported to be associated with adverse pregnancy outcomes. However, there is limited knowledge regarding the effects of single or mixed PAHs exposure on unexplained recurrent spontaneous abortion (URSA ...

We derive the star formation histories of eight dwarf spheroidal (dSph) Milky Way satellite galaxies from their alpha element abundance patterns. Nearly 3000 stars from our previously published catalog (Paper II) comprise our data set. The average [alpha/

Spin excitations near the pressure‐induced antiferromagnetic transition in SrCu2(BO3)2

Journal of Applied Crystallography, EarlyView.
Inelastic neutron scattering on SrCu2(BO3)2 at 4.2 GPa reveals dispersive spin excitations in the antiferromagnetic phase, consistent with linear‐spin‐wave theory and highlighting the key role of interlayer coupling.SrCu2(BO3)2 is a frustrated quantum magnet which realizes the Shastry–Sutherland model. The system exhibits a sequence of pressure‐induced
