A 32-day Quasi-periodic Modulation in the Post-peak Light Curve of the Superluminous Supernova SN 2018bsz

Aiswarya Sankar. K, Ting-Wan Chen, Seán J. Brennan +8

Recurrent structure in supernova (SN) light curves may reveal physical clocks associated with central-engine dynamics, binary orbital motion, or interaction with structured circums…

Decoding the Early-Time Light Curves of Type Ia Supernovae. II. Population Parameters of One Thousand ZTF Supernovae

Chang Liu, Adam A. Miller, Nikhil Sarin +13

Early-time light curves of Type Ia Supernovae (SNe Ia) encode critical information about their progenitor systems. We characterize the rise of normal SNe Ia using a volume-complete…

Detection of persistent helium absorption in the 91bg-like type Ia Supernova 2022an

Ping Chen, Avishay Gal-Yam, Subo Dong +14

We present optical and near-infrared observations of the fast-declining Type Ia supernova (SN Ia) 2022an. The photometric and spectroscopic properties identify it as a standard 91b…

A Faint Progenitor System for the Faint Supernova 2024vjm

Erez A. Zimmerman, Avishay Gal-Yam, Paul J. Groot +68

Type Ia Supernovae (SNe Ia) are well known for their role as standardizable cosmological candles. Their uniformity is credited to their single origin as thermonuclear explosions of…

Multiwavelength Analysis of Six Luminous Fast Blue Optical Transients

Cassie Sevilla, Anna Y. Q. Ho, Nayana A. J. +43

We present multiwavelength observations and analysis of six luminous fast blue optical transients (LFBOTs) discovered in Zwicky Transient Facility (ZTF) survey data. We identified…

Low-Luminosity Type IIP Supernovae from the Zwicky Transient Facility Census of the Local Universe. I: Luminosity Function, Volumetric Rate

Kaustav K. Das, Mansi M. Kasliwal, Christoffer Fremling +51

We present the luminosity function and volumetric rate of a sample of Type IIP supernovae (SNe) from the Zwicky Transient Facility Census of the Local Universe survey (CLU). This i…

A cosmic formation site of silicon and sulphur revealed by a new type of supernova explosion

Steve Schulze, Avishay Gal-Yam, Luc Dessart +47

The cores of stars are the cosmic furnaces where light elements are fused into heavier nuclei. The fusion of hydrogen to helium initially powers all stars. The ashes of the fusion…

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…
