B5.00001: The Advanced LIGO Detectors Invited Speaker: Peter Fritschel After decades of development, the Advanced LIGO gravitational wave detectors are now operating, and they completed their first observational run in early 2016. Advanced LIGO consists of two 4-km scale interferometric detectors located at separate sites in the US. The first year of detector commissioning that led to the first observation run produced instruments that have several times better sensitivity to gravitational-wave strain than previous instruments. At their final design sensitivity, the detectors will be another factor of 2-3x more sensitive than current performance. This talk will cover the design of Advanced LIGO, explain how the sensitivity improvements have been achieved, and lay out the path to reaching final design sensitivity. [Preview Abstract] |

B5.00002: Searches for GW transients in Advanced LIGO Invited Speaker: Chad Hanna Advanced LIGO recently completed its first observing run, which collected gravitational wave data with unprecedented sensitivity between September 2015 and January 2016. One of Advanced LIGO's primary goals is to detect gravitational waves from transient sources such as the supernova or the coalescence of binary compact objects containing neutron stars and/or stellar mass black holes. We will report on the most recent searches for gravitational wave transients. [Preview Abstract] |

B5.00003: Parameter estimation and tests of General Relativity with GW transients in Advanced LIGO Invited Speaker: Salvatore Vitale The Advanced LIGO observatories have successfully completed their first observation run. Data were collected from September 2015 to January 2016, with a sensitivity a few times better than initial instruments in the hundreds of Hertz band. Bayesian parameter estimation and model selection algorithms can be used to estimate the astrophysical parameters of gravitational-wave sources, as well as to perform tests of General Relativity in its strong-field dynamical regime. In this talk we will describe the methods devised to characterize transient gravitational wave sources and their applications in the advanced gravitational-wave detector era. [Preview Abstract] |
