GW190425: A Compact Binary Coalescence With An Exceptional Total Mass ~3.4 Msun (speaker: Surabhi Sachdev (Penn State) — GRITTS 2/10/2020

Monday February 10, 2020 3:00 pm
NW22 LIGO interaction area

This talk will explore the pre-history of the Laser Interferometer Gravitational-Wave Observatory (LIGO) with a focus on those events led by the MIT team (Rai Weiss, David Shoemaker, Peter Saulson, Jeffrey Livas, Daniel Dewey, Peter Kramer, and Richard Benford) during the late-1970s through the mid-1980s.  Through this history, I argue that a well-formed formulation of the large-scale interferometers and their sites was present throughout this period of LIGO’s pre-history.  Accounts of problem solving related to the prototype design and build, site selection efforts in Maine and at the Idaho National Engineering Lab, and early observation runs of the prototype under varying budget levels will be provided.

Please note: a 2nd GRITTS seminar is scheduled this week on Wednesday 12 Feb at 4pm at LIGO NW22 interaction area.
Speakers: Danielle Frostig and Nathan Lourie from MIT/MKI
