ASD Colloquium Series
|Proposed Wide-Field GW Counterpart Missions for the 2020s
Recent gravitational wave (GW) events detected by LIGO-Virgo have stimulated great interest in the search for related electromagnetic counterparts. In this talk we present two wide-field GW counterpart missions now under study: ISS-TAO (Transient Astrophysics Observer on the ISS), and TAP (Transient Astrophysics Probe). ISS-TAO, a $70M Mission of Opportunity recently awarded a Phase A study, is a wide-field X-ray transient detector proposed to be deployed on the International Space Station in 2022. Through its unique Lobster imaging X-ray optics that allow high FoV, and good position resolution and sensitivity, ISS-TAO will observe X-ray counterparts of LIGO gravitational wave detections involving neutron stars and black holes. TAP, selected for a funded Probe Concept Study, is a $1B wide-field high-energy transient satellite proposed for flight starting in the late 2020s. TAP includes a soft X-ray telescope and IR telescope as well as Lobster X-ray optics. TAP will observe X-ray and IR counterparts of GWs involving neutron stars and stellar mass black holes detected by LIGO, and possibly X-ray counterparts of GWs from supermassive black holes, detected by LISA and Pulsar Timing Arrays. Both missions will also observe many events per year of X-ray transients related to compact objects, including tidal disruptions of stars, supernova shock breakouts, neutron star bursts and superbursts, and high redshift Gamma-Ray Bursts.
ASD Colloquia are Tuesdays at 3:45 pm (Meet the Speaker at 3:30 pm) in Bldg 34, Room W150 unless otherwise noted.
