"Searching for Gravitational Waves Associated with Gamma-Ray Bursts in the Advanced Detector Era"

Gamma-ray bursts are the most luminous electromagnetic events in the universe.
They fall into two, broad categories: long-duration (=2 s) bursts, which are
powered by the core collapse of rapidly rotating massive stars, and
short-duration (=2 s) bursts, for which binary neutron star and neutron
star-black hole mergers are the leading progenitor candidates. In both
scenarios, gravitational waves are expected to accompany the gamma-ray burst,
making these transient phenomena promising events for gravitational-wave
follow-up. In this talk, I review the status of targeted searches for
gravitational waves in association with gamma-ray bursts and discuss the
prospects of joint electromagnetic and gravitation-wave observations. I also
present the results of these searches obtained during the first Advanced LIGO
observing run, which was carried out between September 2015 and January 2016.
