U11.00001: Overview of the Transient Gravitational Wave Sky Invited Speaker: Pablo Laguna Interferometric detectors will very soon give us an unprecedented view of the gravitational-wave sky, and in particular of the explosive and transient Universe. Now is the time to challenge our theoretical understanding of short-duration gravitational-wave signatures from cataclysmic events, their connection to more traditional electromagnetic and particle astrophysics, and the data analysis techniques that will make the observations a reality. This talk provides an overview of a recent community paper that summarized the state of the art, future science opportunities, and current challenges in understanding gravitational-wave transients.

U11.00002: Gamma-Ray Bursts in the Gravitational Wave Era Invited Speaker: Rosalba Perna The observation of gravitational waves will open a new, unexplored window onto the Universe. Among the sources of gravitational wave transients, compact objects such as neutron stars (NSs) and black holes (BHs) will likely play the most important role. In this talk, I will discuss the expected gravitational wave signal in two important situations: when an NS or a BH is born during a core collapse supernova, and when two compact objects (either NS-NS or NS-BH) in a binary merge. These events are believed to be accompanied by a strong electromagnetic signature in gamma rays -- a long Gamma-Ray Burst from the core collapse event, and a Short Gamma-Ray Burst from the binary merger. I will further discuss what we can learn from the complementary observations of the electromagnetic and the gravitational wave signals during these events. [Preview Abstract] |

U11.00003: Gravitational Wave Observations Expected from the Transient Gravitational Wave Sky Invited Speaker: Laura Cadonati A new observational era in gravitational wave astronomy is poised to begin in this decade, with the upcoming start of Advanced LIGO and Advanced Virgo: the direct detection of gravitational wave transients promises new insights into the engines powering some of the most energetic astrophysical events. In this talk, I will outline the path towards their detection with the second generation of gravitational wave interferometers, with focus on gravitational wave transients: coalescences of neutron star and/or black hole binary systems, core-collapse supernovae, isolated neutron star instabilities. I will discuss the open analysis challenges, the prospects for astrophysical inference and the potential for multi-messenger astronomy with combined information from the electromagnetic and neutrino sectors.
