SUMMARY:Speaker: Luke Kelley (UC Berkeley) - Title: Nanohertz Gravitational Waves: Exploring the most massive black holes in the Universe
DESCRIPTION:Research Progress Meeting \nDate: October 12\, 2023 \nTime: 4:00- 5:00 pm \nLocation: Sessler Conference Room- 50A-5132 [In-Person and HYBRID]  \nSpeaker: Luke Kelley (UC Berkeley) \nTitle: Nanohertz Gravitational Waves: Exploring the most massive black holes in the Universe\n \nAbstract: Earlier this year NANOGrav\, along with other pulsar timing arrays\, announced strong evidence for a stochastic gravitational wave (GW) background at nanohertz frequencies. For decades\, such a signal has been predicted from binaries of supermassive black holes (SMBHs). I will present NANOGrav’s recent data and our interpretation of the signal as produced by SMBH binaries. I will show that these GWs encode a wealth of new information about SMBH formation and evolution. Now\, the race is on for the next expected measurements: detection of anisotropy in the GW background\, and individual loud binaries. These measurements would confirm the origin of the GWs\, provide a crucial testbed for the future LISA mission\, and open a new multi-messenger window into the Universe. \nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/98854322464?pwd=K2tKUm1VZjRlV1J5RHE3cXdHQzRxdz09\n\nMeeting ID: 988 5432 2464\n\nPasscode: 142239
