Radio Constraints on the Circumstellar Environment of the Type IIb Supernova SN 2024iss

Yuhei Iwata, Tomoki Matsuoka, Masanori Akimoto +6

Type~IIb supernovae exhibit diverse progenitor properties, and radio observations offer a unique probe of their mass-loss histories shortly before the explosion. We present Japanes…

Constraints on the VHE counterpart of two binary black hole mergers observed by the MAGIC and CTAO LST-1 telescopes

K. Abe, S. Abe, J. Abhir +439

We present very-high-energy gamma-ray observations of two binary black hole merger candidates, GW240615_113620 and GW241125_010116, performed with the Major Atmospheric Gamma Imagi…

Electron-capture Supernova Candidates from Light Curves: Implications for Their Progenitors and Explosion Properties

Masato Sato, Nozomu Tominaga, Sergei I. Blinnikov +5

Core-collapse supernovae are explosions of massive stars. While most massive stars end as iron-core-collapse supernovae, less massive stars are expected to explode as electron-capt…
