DAMA CoGeNT without astrophysical uncertainties
font style='font-size:12px;'>
2011/10/18
The CoGeNT collaboration has reported evidence of an annual modulation in its first fifteen months of data. Here we compare the amplitude and phase of this signal to the modulation observed by the DAM...

Surface tension old chiral transition astrophysical applications
font style='font-size:12px;'>
2011/10/18
The surface tension of cold and dense QCD phase transitions has appeared recently as a key ingredient in different astrophysical scenarios, ranging from core-colapse supernovae explosions to compact s...
Adaptive image ray-tracing for astrophysical simulations
Adaptive image ray-tracing astrophysical simulations
font style='font-size:12px;'>
2011/1/11
A technique is presented for producing synthetic images from numerical simulations whereby the image resolution is adapted around prominent features. In so doing, adaptive image ray-tracing (AIR) impr...
Modeling maximum astrophysical gravitational recoil velocities
maximum astrophysical gravitational recoil velocities
font style='font-size:12px;'>
2010/11/16
We measure the recoil velocity as a function of spin for equal-mass, highly-spinning black-hole
binaries, with spins in the orbital plane, equal in magnitude and opposite in direction. We con rm that...
Integrating Out Astrophysical Uncertainties
Astrophysical Uncertainties
