Constraining inhomogeneities and asymmetries in SNe, FBOTs, and other high-energy transients from unresolved radio observations
Fabio De Colle, Rosa L. Becerra, Lizeth A. Meza +7
Synchrotron emission in high-energy transients is produced by relativistic electrons accelerated by shocks. As high-energy transients are often unresolved even on angular scales pr…
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…
The first radio view of a type Ibn supernova in SN 2023fyq: Understanding the mass-loss history in the last decade before the explosion
Raphael Baer-Way, A. J. Nayana, Wynn Jacobson-Galan +13
Supernovae that interact with hydrogen-poor, helium-rich circumstellar material (CSM), known as Type Ibn supernovae (SNe Ibn), present a unique opportunity to probe mass-loss proce…
The Most Luminous Known Fast Blue Optical Transient AT 2024wpp: Unprecedented Evolution and Properties in the X-rays and Radio
A. J. Nayana, Raffaella Margutti, Eli Wiston +34
We present X-ray (0.3--79 keV) and radio (0.25--203 GHz) observations of the most luminous Fast Blue Optical Transient (LFBOT) AT\,2024wpp at , spanning 2--280 days after…
A Multiwavelength Autopsy of the Interacting IIn Supernova 2020ywx: Tracing its Progenitor Mass-Loss History for 100 Years before Death
Raphael Baer-Way, Poonam Chandra, Maryam Modjaz +31
While the subclass of interacting supernovae with narrow hydrogen emission lines (SNe IIn) consists of some of the longest-lasting and brightest SNe ever discovered, their progenit…
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…
