Shock-cooling Constraints via Early-time Observations of the Type IIb SN 2022hnt
Joseph R. Farah, D. Andrew Howell, Giacomo Terreran +8
We report the results of a rapid follow-up campaign on the Type IIb Supernova (SN) 2022hnt. We present a daily, multi-band, photometric follow-up using the Las Cumbres Observatory,…
Spectroscopic observations of progenitor activity 100 days before a Type Ibn supernova
S. J. Brennan, J. Sollerman, I. Irani +30
Obtaining spectroscopic observations of the progenitors of core-collapse supernovae is often unfeasible due to an inherent lack of knowledge as to which stars will go supernova and…
SN 2021adxl: A luminous nearby interacting supernova in an extremely low metallicity environment
S. J. Brennan, S. Schulze, R. Lunnan +17
SN 2021adxl is a slowly evolving, luminous, Type IIn supernova with asymmetric emission line profiles, similar to the well-studied SN 2010jl. We present extensive optical, near-ult…
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…
The Early Ultraviolet Light-Curves of Type II Supernovae and the Radii of Their Progenitor Stars
Ido Irani, Jonathan Morag, Avishay Gal-Yam +18
We present a sample of 34 normal SNe II detected with the Zwicky Transient Facility, with multi-band UV light-curves starting at days after explosion, as well as X-ray d…
Resolving the explosion of supernova 2023ixf in Messier 101 within its complex circumstellar environment
E. A. Zimmerman, I. Irani, P. Chen +54
Observing a supernova explosion shortly after it occurs can reveal important information about the physics of stellar explosions and the nature of the progenitor stars of supernova…
Shock cooling emission from explosions of red super-giants: II. An analytic model of deviations from blackbody emission
Jonathan Morag, Ido Irani, Nir Sapir +1
Light emission in the first hours and days following core-collapse supernovae (SNe) is dominated by the escape of photons from the expanding shock heated envelope. In a preceding p…
1100 days in the life of the supernova 2018ibb -- The best pair-instability supernova candidate, to date
Steve Schulze, Claes Fransson, Alexandra Kozyreva +63
Abridged - Stars with ZAMS masses between 140 and are thought to explode as pair-instability supernovae (PISNe). During their thermonuclear runaway, PISNe can produce…
A Systematic Study of Ia-CSM Supernovae from the ZTF Bright Transient Survey
Yashvi Sharma, Jesper Sollerman, Christoffer Fremling +35
Among the supernovae (SNe) that show strong interaction with the circumstellar medium, there is a rare subclass of Type Ia supernovae, SNe Ia-CSM, that show strong narrow hydrogen…
The prevalence and influence of circumstellar material around hydrogen-rich supernova progenitors
Rachel J. Bruch, Avishay Gal-Yam, Ofer Yaron +44
Narrow transient emission lines (flash-ionization features) in early supernova (SN) spectra trace the presence of circumstellar material (CSM) around the massive progenitor stars o…
SN 2022oqm -- a Ca-rich explosion of a compact progenitor embedded in C/O circumstellar material
I. Irani, Ping Chen, Jonathan Morag +27
We present the discovery and analysis of SN\,2022oqm, a Type Ic supernova (SN) detected \,day after explosion. The SN rises to a blue and short-lived (2\,days) initial peak. Ea…
The Type Icn SN 2021csp: Implications for the Origins of the Fastest Supernovae and the Fates of Wolf-Rayet Stars
Daniel A. Perley, Jesper Sollerman, Steve Schulze +31
We present observations of SN 2021csp, the second example of a newly-identified type of supernova (Type Icn) hallmarked by strong, narrow, P Cygni carbon features at early times. T…
Less than 1% of Core-Collapse Supernovae in the local universe occur in elliptical galaxies
I. Irani, S. J. Prentice, S. Schulze +39
We present observations of three Core-collapse supernovae (CCSNe) in elliptical hosts, detected by the Zwicky Transient Facility Bright Transient Survey (BTS). SN 2019ape is a SN I…
The Zwicky Transient Facility Bright Transient Survey. II. A Public Statistical Sample for Exploring Supernova Demographics
Daniel A. Perley, Christoffer Fremling, Jesper Sollerman +34
We present a public catalog of transients from the Zwicky Transient Facility (ZTF) Bright Transient Survey (BTS), a magnitude-limited (m<19 mag in either the g or r filter) survey…
Bright, months-long stellar outbursts announce the explosion of interaction-powered supernovae
Nora L. Strotjohann, Eran O. Ofek, Avishay Gal-Yam +53
Interaction-powered supernovae (SNe) explode within an optically-thick circumstellar medium (CSM) that could be ejected during eruptive events. To identify and characterize such pr…
