The next generation of gravitational wave counterpart discovery

Colloquium with Dr. Charles Kilpatrick, CIERA Fellow, Northwestern University

The promise of multi-messenger astronomy was spectacularly realized in 2017 with the detection of a binary neutron star merger, GW170817, simultaneously localized by LIGO/Virgo in gravitational waves and telescopes observing across the electromagnetic spectrum.  This single event led to ground-breaking new discoveries in the physics of compact objects, synthesis of heavy elements, and cosmology.  The challenges of extending these discoveries to a large population of electromagnetic counterparts will require new observing and analysis techniques, instrumentation, and collaborations.  On the heels of this seminal discovery, I will discuss our results from the most recent LIGO/Virgo observing run to detect new gravitational wave counterparts and the ongoing efforts to rapidly coordinate a global networks of telescopes, identify their multi-wavelength counterparts, and use these observations to further expand our understanding of compact objects and fundamental physics.  I will then discuss new facilities and observational programs, where I am leading efforts to extend search and follow up into the X-ray, ultraviolet, and infrared.  These include wide-field, multi-wavelength counterpart searches in the ground and space, JWST imaging and spectra for well-localized counterparts, and an ongoing infrared time-domain survey with hundreds of infrared spectra for comparison to candidate gravitational wave counterparts.
