An infrared echo from a circumstellar disk in the hydrogen- and helium-poor SN 2024aecx

Samaporn Tinyanont, Kittipong Wangnok, Jennifer E. Andrews +34

We present near-infrared (NIR) spectroscopy of the hydrogen- and helium-poor (Type Ic) supernova (SN) 2024aecx, which displays a strong NIR excess emerging 32 days post peak. SN 20…

VLBI Observations of SN 2012au Reveal a Compact Radio Source a Decade Post Explosion

Mattias Lazda, Kenzie Nimmo, Maria R. Drout +13

Three leading models have been put forth to justify the observed radio re-brightening associated with stripped-envelope supernovae (SESNe) years post-explosion: radiation from an e…

Hydrogen-Poor Superluminous Supernovae in the Nebular Phase: Spectral Diversity Due to Ejecta Ionization as a Probe of the Power Source

Peter K. Blanchard, Edo Berger, Sebastian Gomez +6

We present a large sample of 39 nebular-phase optical spectra of 25 hydrogen-poor superluminous supernovae (SLSNe-I) and jointly analyze them with previously published spectra of 1…

Dichotomy in Long-Lived Radio Emission from Tidal Disruption Events AT 2020zso and AT 2021sdu: Multi-Component Outflows vs. Host Contamination

Collin T. Christy, Kate D. Alexander, Tanmoy Laskar +16

We present a detailed radio study of the tidal disruption events (TDEs) AT 2020zso and AT 2021sdu. Both exhibit transient radio emission beginning shortly after optical discovery a…

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…
