Implications from Late-Time X-ray Detections of Optically Selected Tidal Disruption Events: State Changes, Unification, and Detection Rates
P. G. Jonker, N. C. Stone, A. Generozov +2
We present Chandra X-ray observations of four optically-selected tidal disruption events (TDEs) obtained 4-9 years after discovery. Three sources were detected with luminosities be…
A New Class of Changing-Look LINERs
Sara Frederick, Suvi Gezari, Matthew J. Graham +28
We report the discovery of six active galactic nuclei (AGN) caught "turning on" during the first nine months of the Zwicky Transient Facility (ZTF) survey. The host galaxies were c…
Transient processing and analysis using : Alert Management, Photometry and Evaluation of Lightcurves
J. Nordin, V. Brinnel, J. van Santen +18
Both multi-messenger astronomy and new high-throughput wide-field surveys require flexible tools for the selection and analysis of astrophysical transients. We here introduce the A…
Evidence for rapid disk formation and reprocessing in the X-ray bright tidal disruption event AT 2018fyk
T. Wevers, D. R. Pasham, S. van Velzen +15
We present optical spectroscopic and Swift UVOT/XRT observations of the X-ray and UV/optical bright tidal disruption event (TDE) AT 2018fyk/ASASSN-18ul discovered by ASAS-SN. The S…
The Palomar Transient Factory Sky2Night programme
J. van Roestel, P. J. Groot, T. Kupfer +9
We present results of the Sky2Night project: a systematic, unbiased search for fast optical transients with the Palomar Transient Factory. We have observed 407 deg in -band…
The Zwicky Transient Facility: Science Objectives
Matthew J. Graham, S. R. Kulkarni, Eric C. Bellm +114
The Zwicky Transient Facility (ZTF), a public-private enterprise, is a new time domain survey employing a dedicated camera on the Palomar 48-inch Schmidt telescope with a 47 deg$^2…
