Observing gravitational waves with Advanced detectors

Abstract:  The dawn of gravitational wave astronomy is upon us as Advanced LIGO and Advanced Virgo begin to come on line later this year. At design sensitivity, these Advanced gravitatinal wave detectors will increase our sensitive distance by a factor of 10 (to about 200Mpc), compared to the previous generation, leading to 3 order of magnitude increase in the sensitive volume to compact binary coalescences.

In order to perform gravitational wave astronomy, one must decipher the astrophysical information encoded in the detected gravitational wave signals. This talk will begin with an overview of Advanced LIGO and Advanced Virgo before presenting the prospects for gravitational wave astronomy in Advanced detector era. Then, a brief overview of the methods for performing gravitational wave astronomy, based on Bayesian inference, will be presented, followed by highlights of some examples of gravitational wave astronomy for "unmodelled" Burst gravitational wave signals and other transients signals.
