Spectral Diversity in Type Ibn Supernovae and the Large Host Offset of SN2024acyl
Yize Dong, V. Ashley Villar, Anya Nugent +35
In this paper, we first present observations of SN~2024acyl, a normal Type Ibn supernova with a large projected offset (35~kpc) from its host galaxy. The low star-formation r…
Delayed radio emission in tidal disruption events from collisions of outflows driven by disk instabilities
Samantha C. Wu, Daichi Tsuna, Brenna Mockler +1
Delayed radio emission has been associated with a growing proportion of tidal disruption events (TDEs). For many events, the radio synchrotron emission is inferred to originate fro…
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…
Fates of Rotating Supergiants from Stellar Mergers and the Landscape of Transients upon Core-collapse
Daichi Tsuna, Jim Fuller, Wenbin Lu
We present a grid of rotating supergiant models from post-main sequence binary merger products, constructed by the MESA stellar evolution code. We focus on the evolution of these s…
Population Synthesis Study on the Binary Origin of Type Ibn Supernovae
Takatoshi Ko, Tomoya Kinugawa, Daichi Tsuna +2
Type Ibn supernovae (SNe) are a class of SN explosions whose progenitors are surrounded by dense helium-rich circumstellar matter (CSM). Some models have been proposed for how to f…
