SUMMARY:The next generation of gravitational wave counterpart discover
 y\, Astronomy Colloquium\, Charlie Kilpatrick\, Northwestern Universit
 y
DESCRIPTION: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 wa
 ves and telescopes observing across the electromagnetic spectrum.  Thi
 s single event led to ground-breaking new discoveries in the physics o
 f compact objects\, synthesis of heavy elements\, and cosmology.  The 
 challenges of extending these discoveries to a large population of ele
 ctromagnetic counterparts will require new observing and analysis tech
 niques\, instrumentation\, and collaborations.  On the heels of this s
 eminal discovery\, I will discuss our results from the most recent LIG
 O/Virgo observing run to detect new gravitational wave counterparts an
 d the ongoing efforts to rapidly coordinate a global networks of teles
 copes\, identify their multi-wavelength counterparts\, and use these o
 bservations to further expand our understanding of compact objects and
  fundamental physics.  I will then discuss new facilities and observat
 ional programs\, where I am leading efforts to extend search and follo
 w 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 on
 going infrared time-domain survey with hundreds of infrared spectra fo
 r comparison to candidate gravitational wave counterparts.
