C5.00001: The future of ground based GW astrophysics Invited Speaker: Alessandra Corsi With Advanced LIGO operational since September 2015, and with Virgo and KAGRA detectors expected to join forces in the coming years, a new observational era in ground-based gravitational wave astronomy is now beginning. Indeed, gravitational waves could open a totally new view of the transient sky, and shed new light on the engines powering some of the most energetic astrophysical events. In this talk, I will discuss recent results, open challenges, and prospects for the study of astrophysical gravitational wave transients, and the opportunities for multi-messenger astrophysics with gravitational waves enabled by the advanced gravitational wave detectors.

C5.00002: Terrestrial Gravitational-Wave Detector Arrays in the 21st Century Invited Speaker: Stefan Ballmer The early observation runs of the two Advanced LIGO interferometers mark the beginning of gravitational-wave astronomy. The extend to which this new branch of astronomy can bloom depends soley on the quality and number of available detectors. I will outline the plans of LIGO and its partners VIRGO and KAGRA for achieving design sensitivity and upgrading the detectors. Furthermore I will explore the options for future gravitational-wave detector arrays, a generarion of detectors that can provide the backbone infrastructure for gravitational-wave astronomy for the rest of the 21st century.

C5.00003: Techniques to extend the reach of ground based gravitational wave detectors Invited Speaker: Sheila Dwyer While the current generation of advanced ground based detectors will open the gravitational wave universe to observation, ground based interferometry has the potential to extend the reach of these observatories to high redshifts. Several techniques have the potential to improve the advanced detectors beyond design sensitivity, including the use of squeezed light, upgraded suspensions, and possibly new optical coatings, new test mass materials, and cryogenic suspensions. To improve the sensitivity by more than a factor of 10 compared to advanced detectors new, longer facilities will be needed. Future observatories capable of hosting interferometers 10s of kilometers long have the potential to extend the reach of gravitational wave astronomy to cosmological distances, enabling detection of binary inspirals from throughout the history of star formation.
