Physical Review D, 2017 Many theories of dark matter (DM) predict that DM particles can be captured by stars via scattering on ordinary matter. They subsequently condense into a DM core close to the center of the star and eventually annihilate. In this work, we trace DM capture and annihilation rates throughout the life of a massive star and show that this evolution ...Brdar, Vedran, Kopp, Joachim, Liu, Jiaopenaire +3 more sourcesShort-Duration Gamma-Ray Bursts [PDF]
, 2013 Gamma-ray bursts (GRBs) display a bimodal duration distribution with a separation between the short- and long-duration bursts at about 2 s.
