Type Ia Supernovae from Merging White Dwarfs I. Prompt Detonations
Rainer Moll, Cody Raskin, Daniel Kasen +1
Merging white dwarfs are a possible progenitor of Type Ia supernovae (SNe Ia). While it is not entirely clear if and when an explosion is triggered in such systems, numerical model…

MAGIC upper limits on the GRB 090102 afterglow
MAGIC Collaboration, J. Aleksić, S. Ansoldi +160
Indications of a GeV component in the emission from GRBs are known since the EGRET observations during the 1990's and they have been confirmed by the data of the Fermi satellite. T…
Off-axis irradiation and the polarization of broad emission lines in active galactic nuclei
Rene W. Goosmann, C. Martin Gaskell, Frederic Marin
The STOKES Monte Carlo radiative transfer code has been extended to model the velocity dependence of the polarization of emission lines. We use STOKES to present improved modelling…
