A very luminous jet from the disruption of a star by a massive black hole
Igor Andreoni, Michael W. Coughlin, Daniel A. Perley +78
Tidal disruption events (TDEs) are bursts of electromagnetic energy released when supermassive black holes (SMBHs) at the centers of galaxies violently disrupt a star that passes t…
Volumetric rates of Luminous Red Novae and Intermediate Luminosity Red Transients with the Zwicky Transient Facility
Viraj R. Karambelkar, Mansi M. Kasliwal, Nadejda Blagorodnova +27
Luminous red novae (LRNe) are transients characterized by low luminosities and expansion velocities, and are associated with mergers or common envelope ejections in stellar binarie…
The Interaction of Supernova 2018evt with a Substantial Amount of Circumstellar Matter -- An SN1997cy-like Event
Yi Yang, Dietrich Baade, Peter Hoeflich +29
A rare class of supernovae (SNe) is characterized by strong interaction between the ejecta and several solar masses of circumstellar matter (CSM) as evidenced by strong Balmer-line…
A search for relativistic ejecta in a sample of ZTF broad-lined Type Ic supernovae
Alessandra Corsi, Anna Y. Q. Ho, S. Bradley Cenko +23
The dividing line between gamma-ray bursts (GRBs) and ordinary stripped-envelope core-collapse supernovae (SNe) is yet to be fully understood. Observationally mapping the variety o…
Probing the low-mass end of core-collapse supernovae using a sample of strongly-stripped Calcium-rich Type IIb Supernovae from the Zwicky Transient Facility
Kaustav K. Das, Mansi M. Kasliwal, Christoffer Fremling +23
The fate of stars in the zero-age main-sequence (ZAMS) range Msun is unclear. They could evolve to form white dwarfs or explode as electron-capture supernovae (SNe)…
The Zwicky Transient Facility phase I sample of hydrogen-rich superluminous supernovae without strong narrow emission lines
Tuomas Kangas, Lin Yan, Steve Schulze +19
We present a sample of 14 hydrogen-rich superluminous supernovae (SLSNe II) from the Zwicky Transient Facility (ZTF) between 2018 and 2020. We include all classified SLSNe with pea…
The Tidal Disruption Event AT2021ehb: Evidence of Relativistic Disk Reflection, and Rapid Evolution of the Disk-Corona System
Yuhan Yao, Wenbin Lu, Muryel Guolo +29
We present X-ray, UV, optical, and radio observations of the nearby ( Mpc) tidal disruption event (TDE) AT2021ehb/ZTF21aanxhjv during its first 430 days of evolution. AT…
SRGA J181414.6-225604: A new Galactic symbiotic X-ray binary outburst triggered by an intense mass loss episode of a heavily obscured Mira variable
Kishalay De, Ilya Mereminskiy, Roberto Soria +24
We present the discovery and multi-wavelength characterization of SRGA J181414.6-225604, a Galactic hard X-ray transient discovered during the ongoing SRG/ART-XC sky survey. Using…
The long-active afterglow of GRB 210204A: Detection of the most delayed flares in a Gamma-Ray Burst
Harsh Kumar, Rahul Gupta, Divita Saraogi +22
We present results from extensive broadband follow-up of GRB 210204A over the period of thirty days. We detect optical flares in the afterglow at 7.6 x 10^5 s and 1.1 x 10^6 s afte…
In search of short gamma-ray burst optical counterpart with the Zwicky Transient Facility
Tomás Ahumada, Shreya Anand, Michael W. Coughlin +46
The Fermi Gamma-ray Burst Monitor (GBM) triggers on-board in response to 40 short gamma-ray bursts (SGRBs) per year; however, their large localization regions have made the…
The Search for a Counterpart to NuSTAR J053449+2126.0
Antonio C. Rodriguez, Yuhan Yao, Kishalay De +1
Tumer et al. 2022, ATel #15171, have recently reported the discovery of an X-ray source, NuSTAR J053449+2126.0, during a calibration observation which took place on 25 April 2020.…
The Final Season Reimagined: 30 Tidal Disruption Events from the ZTF-I Survey
Erica Hammerstein, Sjoert van Velzen, Suvi Gezari +30
Tidal disruption events (TDEs) offer a unique way to study dormant black holes. While the number of observed TDEs has grown thanks to the emergence of wide-field surveys in the pas…
A Tight Three-parameter Correlation and Related Classification on Gamma-Ray Bursts
Shuai Zhang, Lang Shao, Bin-Bin Zhang +4
Gamma-ray bursts (GRBs) are widely believed to be from massive collapsars and/or compact binary mergers, which accordingly, would generate long and short GRBs, respectively. The de…
