"What Can Galaxy Evolution Tell Us About Short Gamma-Ray Bursts?" (host: Shardha Jogee)
We use recent constraints on the star formation rate---halo mass---redshift
relation to model the host halo environments where short Gamma-Ray Burst
(sGRB) progenitors are created. These halo environments set minimum energy
requirements for sGRB progenitors to leave the vicinity of their original
galaxy. We find that the fraction of sGRBs which are hostless is a robust
probe of the underlying velocity kick distribution for sGRB progenitors,
regardless of uncertainties in the sGRB time-delay distribution and
observational systematics. We use observed constraints on the hostless
fraction of sGRBs to rule out several sGRB progenitor classes which cannot
supply the necessary velocity kicks. Finally, we discuss the ability of
sGRB galaxy host properties (e.g., stellar mass and morphology) to further
constrain model uncertainties.
