Identifying LISA Gravitational-Wave sources using the optical time domain

Speaker:

Friday, September 4, 2020 - 2:00pm to 3:00pm

In this talk, I will describe ongoing work using the Zwicky Transient Facility (ZTF) to identify ultracompact binaries (P<60 min) which are candidate gravitational wave sources detectable by the Laser Interferometer Space Antenna (LISA). So far, this work has resulted in the discovery of 16 newly identified binary systems with orbital periods under an hour, including seven eclipsing systems, two of which have orbital periods under 10 minutes (making them the shortest period eclipsing binary systems known). Three of the systems will be very strong (SNR>50) LISA gravitational wave sources, and many of the others should be detectable at lower SNR.
