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…

Luminous Late-time Radio Emission from Supernovae Interacting with Circumbinary Material

Samantha C. Wu, Daichi Tsuna

Numerous core-collapse supernovae (CCSNe) exhibit signatures of interaction with circumstellar material (CSM). Bright radio emission years after the SN is one such indication of de…

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…

Accretion from a shock-inflated companion: double-peaked supernova lightcurve with periodic modulations

Wenbin Lu, Savannah Cary, Daichi Tsuna

We study the observational signatures from the interactions between a newly born neutron star and a companion star that is impacted by the supernova ejecta. We focus on the cases w…
