    • A Comprehensive Study of Detectability and Contamination in Deep Rapid Optical Searches for Gravitational Wave Counterparts 

      Cowperthwaite, Philip Steven; Berger, Edo (IOP Publishing, 2015)
      The first direct detection of gravitational waves (GW) by the ground-based Advanced LIGO/Virgo interferometers is expected to occur within the next few years. These interferometers are designed to detect the mergers of ...

C.; Suchyta, E.; Tarle, G.; Thomas, D.; Thomas, R. C.; Tucker, D. L.; Weller, J. (American Astronomical Society, 2016)
      We report the results of a Dark Energy Camera (DECam) optical follow-up of the gravitational wave (GW) event GW151226, discovered by the Advanced LIGO detectors. Our observations cover 28.8 deg2 of the localization region ...
