AT 2019avd: A novel addition to the diverse population of nuclear transients
A. Malyali, A. Rau, A. Merloni +29
We report on SRG/eROSITA, ZTF, ASAS-SN, Las Cumbres, NEOWISE-R, and Swift XRT/UVOT observations of the unique ongoing event AT 2019avd, located in the nucleus of a previously inact…
SN2020bvc: a Broad-lined Type Ic Supernova with a Double-peaked Optical Light Curve and a Luminous X-ray and Radio Counterpart
A. Y. Q. Ho, S. R. Kulkarni, D. A. Perley +34
We present optical, radio, and X-ray observations of SN2020bvc (=ASASSN20bs; ZTF20aalxlis), a nearby (; =114 Mpc) broad-lined (BL) Type Ic supernova (SN). Our observat…
Helium-rich Superluminous Supernovae From the Zwicky Transient Facility
Lin Yan, D. Perley, S. Schulze +39
Helium is expected to be present in the ejecta of some hydrogen-poor superluminous supernovae (SLSN-I). However, so far only one event, PTF10hgi has been identified with He feature…
AT2018lqh and the nature of the emerging population of day-scale duration optical transients
E. O. Ofek, S. M. Adams, E. Waxman +18
We report on the discovery of AT2018lqh (ZTF18abfzgpl) -- a rapidly-evolving extra-galactic transient in a star-forming host at 242 Mpc. The transient g-band light curve's duration…
Candidate Electromagnetic Counterpart to the Binary Black Hole Merger Gravitational Wave Event S190521g
M. J. Graham, K. E. S. Ford, B. McKernan +24
We report the first plausible optical electromagnetic (EM) counterpart to a (candidate) binary black hole (BBH) merger. Detected by the Zwicky Transient Facility (ZTF), the EM flar…
The GROWTH Marshal: A Dynamic Science Portal for Time-Domain Astronomy
M. M. Kasliwal, C. Cannella, A. Bagdasaryan +9
We describe a dynamic science portal called the GROWTH Marshal that allows time-domain astronomers to define science programs, program filters to save sources from different discov…
