XENON10/100 dark matter constraints in comparison with CoGeNT and DAMA: examining the Leff dependence

Christopher Savage, Graciela Gelmini, Paolo Gondolo +1

We consider the compatibility of DAMA/LIBRA, CoGeNT, XENON10 and XENON100 results for spin-independent (SI) dark matter Weakly Interacting Massive Particles (WIMPs), particularly a…

The WIMP capture process for dark stars in the early universe

Sofia Sivertsson, Paolo Gondolo

The first stars to form in the universe may have been dark stars, powered by dark matter annihilation instead of nuclear fusion. The initial amount of dark matter gathered by the s…

Numerical simulations of the decay of primordial magnetic turbulence

Tina Kahniashvili, Axel Brandenburg, Alexander G. Tevzadze +1

We perform direct numerical simulations of forced and freely decaying 3D magnetohydrodynamic turbulence in order to model magnetic field evolution during cosmological phase transit…

A change in the optical polarization associated with a gamma-ray flare in the blazar 3C 279

LAT Collaboration, members of the 3C 279 multi-band campaign

It is widely accepted that strong and variable radiation detected over all accessible energy bands in a number of active galaxies arises from a relativistic, Doppler-boosted jet po…

Spectra and Light Curves of Six Type Ia Supernovae at 0.511 < z < 1.12 and the Union2 Compilation

R. Amanullah, C. Lidman, D. Rubin +42

We report on work to increase the number of well-measured Type Ia supernovae (SNe Ia) at high redshifts. Light curves, including high signal-to-noise HST data, and spectra of six S…

Gravitational waves from first order phase transitions during inflation

Diego Chialva

We study the production, spectrum and detectability of gravitational waves in models of the early Universe where first order phase transitions occur during inflation. We consider a…
