Title:Astronomy with LIGO

Abstract: The Advanced LIGO detectors are scheduled to come online in just one year and are expected to reach their design sensitivity by 2018. They promise to finally open up the window of gravitational-wave astronomy. A number of scientific analyses with Initial LIGO led to interesting upper limits and have given us a taste of how multi-messenger astronomy will develop in the next few years. The forefront of LIGO data analysis has shifted from signal searches and detection to signal interpretation and astronomical measurements. I will discuss recent advances in how to best extract astrophysical information from inspiral signals of compact object binaries and highlight some of the challenges along the way. In particular, I will focus on how accurately we can localize sources, connect them to short gamma-ray bursts and other electromagnetic transients, and measure black hole masses and spins.
