The First Tidal Disruption Flare in ZTF: From Photometric Selection to Multi-wavelength Characterization
The First Tidal Disruption Flare in ZTF: From Photometric Selection to Multi-wavelength Characterization
We present Zwicky Transient Facility (ZTF) observations of the tidal disruption flare AT2018zr/PS18kh reported by Holoien et al. and detected during ZTF commissioning. The ZTF light curve of the tidal disruption event (TDE) samples the rise-to-peak exceptionally well, with 50 days of g- and r-band detections before the time of …
