Title: DECam Follow-Up of Advanced LIGO/Virgo Observing Run 2

Abstract: Advanced LIGO recently achieved the first direct detection of gravitational waves, and our rapid DECam follow-up of the first event (GW,150914) covered more area and to a greater depth than any other optical facility. Observing Run 2 (Aug 2016--Feb 2017) will have greater sensitivity and will likely detect the first binary neutron star (BNS) mergers, along with $sim!15$ black hole binary (BBH) mergers. The most promising EM counterpart for BNS mergers is a ``kilonova'' -- a dim ($z_{rm peak}!approx!21$ mag), red ($i-z!approx!1$ mag), and fast-evolving ($approx!1$ week) transient powered by $r$-process heavy nuclei. The claimed detection of a contemporaneous short GRB in GW,150914 also raises the possibility that BBH mergers may be accompanied by dim off-axis optical afterglows. DECam is the only instrument in the southern hemisphere capable of detecting such faint and rapidly-evolving counterparts across large sky regions, and here we propose to continue our community-DES-LIGO program to pursue joint GW/EM detections. We will observe up to 1 BNS merger and 1 well-localized high signal-to-noise ratio BBH merger.
