A search for successful and choked jets in nearby broad-lined Type Ic supernovae
Tanner O'Dwyer, Alessandra Corsi, Sheng Yang +16
The observational link between long gamma-ray bursts (GRBs) and broad-lined stripped-envelope core-collapse supernovae (SNe Ic-BL) is well established. Significant progress has bee…
Optical and Radio Analysis of Systematically Classified Broad-lined Type Ic Supernovae from the Zwicky Transient Facility
Gokul P. Srinivasaragavan, Sheng Yang, Shreya Anand +35
We study a magnitude-limited sample of 36 Broad-lined Type Ic Supernovae (SNe Ic-BL) from the Zwicky Transient Facility Bright Transient Survey (detected between March 2018 and Aug…
Minutes-duration Optical Flares with Supernova Luminosities
Anna Y. Q. Ho, Daniel A. Perley, Ping Chen +74
In recent years, certain luminous extragalactic optical transients have been observed to last only a few days. Their short observed duration implies a different powering mechanism…
A 12.4 day periodicity in a close binary system after a supernova
Ping Chen, Avishay Gal-Yam, Jesper Sollerman +37
Neutron stars and stellar-mass black holes are the remnants of massive star explosions. Most massive stars reside in close binary systems, and the interplay between the companion s…
Characterizing the Ordinary Broad-lined Type Ic SN 2023pel from the Energetic GRB 230812B
Gokul P. Srinivasaragavan, Vishwajeet Swain, Brendan M. O'Connor +39
We report observations of the optical counterpart of the long gamma-ray burst (LGRB) GRB 230812B, and its associated supernova (SN) SN 2023pel. The proximity () and high…
Probing pre-supernova mass loss in double-peaked Type Ibc supernovae from the Zwicky Transient Facility
Kaustav K. Das, Mansi M. Kasliwal, Jesper Sollerman +34
Eruptive mass loss of massive stars prior to supernova (SN) explosion is key to understanding their evolution and end fate. An observational signature of pre-SN mass loss is the de…
Magnetar Flare-Driven Bumpy Declining Light Curves in Hydrogen-poor Superluminous Supernovae
Xiao-Fei Dong, Liang-Duan Liu, He Gao +1
Recent observations indicate that hydrogen-poor superluminous supernovae often display bumpy declining light curves. However, the cause of these undulations remains unclear. In thi…
A Sensitive Search for Supernova Emission Associated with the Extremely Energetic and Nearby GRB 221009A
Gokul P. Srinivasaragavan, Brendan O' Connor, S. Bradley Cenko +24
We report observations of the optical counterpart of the long gamma-ray burst (LGRB) GRB 221009A. Due to the extreme rarity of being both nearby () and highly energetic…
The Birth of a Relativistic Jet Following the Disruption of a Star by a Cosmological Black Hole
Dheeraj R. Pasham, Matteo Lucchini, Tanmoy Laskar +63
A black hole can launch a powerful relativistic jet after it tidally disrupts a star. If this jet fortuitously aligns with our line of sight, the overall brightness is Doppler boos…
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…
A radio-detected Type Ia supernova with helium-rich circumstellar material
Erik C. Kool, Joel Johansson, Jesper Sollerman +34
Type Ia supernovae (SNe Ia) are thermonuclear explosions of degenerate white dwarf (WD) stars destabilized by mass accretion from a companion star, but the nature of their progenit…
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)…
Observations of the Very Young Type Ia Supernova 2019np with Early-excess Emission
Hanna Sai, Xiaofeng Wang, Nancy Elias-Rosa +30
Early-time radiative signals from type Ia supernovae (SNe Ia) can provide important constraints on the explosion mechanism and the progenitor system. We present observations and an…
Infant-phase reddening by surface Fe-peak elements in a normal Type Ia Supernova
Yuan Qi Ni, Dae-Sik Moon, Maria R. Drout +41
Type Ia Supernovae are thermonuclear explosions of white dwarf stars. They play a central role in the chemical evolution of the Universe and are an important measure of cosmologica…
The early discovery of SN 2017ahn: signatures of persistent interaction in a fast declining Type II supernova
L. Tartaglia, D. J. Sand, J. H. Groh +25
We present high-cadence, comprehensive data on the nearby () Type II SN 2017ahn, discovered within 1 day of explosion, from the very early phases after e…
A mildly relativistic outflow from the energetic, fast-rising blue optical transient CSS161010 in a dwarf galaxy
D. L. Coppejans, R. Margutti, G. Terreran +35
We present X-ray and radio observations of the Fast Blue Optical Transient (FBOT) CRTS-CSS161010 J045834-081803 (CSS161010 hereafter) at t=69-531 days. CSS161010 shows luminous X-r…
