Stringent constraints on the dark matter annihilation cross section from the region of the Galactic Center
Abstract For any realistic halo profile, the Galactic Center is predicted to be the brightest source of gamma-rays from dark matter annihilations. Due in large part to uncertainties associated withExpand
Toward a consistent picture for CRESST, CoGeNT, and DAMA
Three dark matter direct detection experiments (DAMA/LIBRA, CoGeNT, and CRESST-II) have each reported signals which are not consistent with known backgrounds, but resemble that predicted for a darkExpand
Dark Matter implications of DAMA/LIBRA-phase2 results
Abstract Recently, the DAMA/LIBRA collaboration released updated results from their search for the annual modulation signal from Dark Matter (DM) scattering in the detector. Besides approximatelyExpand
Consistent dark matter interpretation for CoGeNT and DAMA/LIBRA
In this paper, we study the recent excess of low-energy events observed by the CoGeNT Collaboration and the annual modulation reported by the DAMA/LIBRA Collaboration, and discuss whether theseExpand
The impact of baryons on the direct detection of dark matter
The spatial and velocity distributions of dark matter particles in the Milky Way Halo affect the signals expected to be observed in searches for dark matter. Results from direct detection experimentsExpand
Linear Gas Dynamics in the Expanding Universe
We investigate the relationship between the dark matter and baryons in the linear regime. This relation is quantified by the so-called ‘‘ filtering scale.’’ We show that a simple Gaussian Ansatz thatExpand
Implications of CoGeNT's New Results For Dark Matter
The CoGeNT Collaboration has recently presented the results of their first 15 months of data, including the measurement of the spectrum of nuclear recoil candidate events, and the time variation ofExpand
Integral equations applied to wave propagation in two dimensions: modeling the tip of a near-field scanning optical microscope.
A Green's-function/Green's-theorem integral equation approach to numerically modeling two-dimensional, s-polarized, wave propagation problems effectively for a variety of geometries was applied to modeling light emission from a near-field scanning optical microscope fiber tip. Expand
Examining the time dependence of DAMA’s modulation amplitude
If dark matter is composed of weakly interacting particles, Earth’s orbital motion may induce a small annual variation in the rate at which these particles interact in a terrestrial detector. TheExpand
A 331 WIMPy dark radiation model
Recent observations suggest that the number of relativistic degrees of freedom in the early universe might exceed what is predicted in the standard cosmological model. If even a small, percent-levelExpand
