C06.00001: Compact Binaries in Advanced LIGO's Third Observing Run Invited Speaker: Chad Hanna Advanced LIGO and Virgo began their third observing run in April 2019 and will continue observing through the end of April 2020. The data taken during this period is the most sensitive gravitational wave data ever and is providing an incredible ability to survey our nearby universe for gravitational wave sources. I will report on the status of gravitational wave searches for compact binaries containing neutron stars and black holes during this third observing run. [Preview Abstract] |

C06.00002: Astrophysical Lessons from LIGO/Virgo's Black Holes Invited Speaker: Maya Fishbach LIGO/Virgo have detected ten binary black holes in their first two observing runs, with several new detections in O3. In this talk, I will review what these detections have taught us about the astrophysical population of binary black holes. I will discuss what we have learned about the pair-instability mass gap in the black hole mass spectrum, black hole spins, the mass ratios of merging binaries, and the redshift evolution of the merger rate. Measuring these population properties enables us to discriminate between black hole formation mechanisms. [Preview Abstract] |

C06.00003: Some Highlights from LIGO and Virgo’s Third Observing Run Invited Speaker: Maximiliano Isi The LIGO and Virgo gravitational-wave detectors continue to produce invaluable information about the nature and distribution of black holes and neutron stars. In this talk, I will provide an overview of some of the highlights from recent observations, and explain their importance for physics and astrophysics. [Preview Abstract] |
