A Search for Extragalactic Fast Blue Optical Transients in ZTF and the Rate of AT2018cow-like Transients

We present a search for extragalactic fast blue optical transients (FBOTs) during Phase I of the Zwicky Transient Facility (ZTF). We identify 38 candidates with durations above half-maximum light 1 day < t _1/2 < 12 days, of which 28 have blue ( g − r ≲ −0.2 mag) colors at peak light. Of the 3...
