The environmental dependence of mid-IR luminous dusty Supernovae
Lin Xiao, Zeyue Peng, Lluis Galbany +10
Using the Spitzer and WISE images, we discovered 42 mid-IR luminous dusty supernovae with local integral-field spectroscopy data. The observed mid-IR emission indicates the presenc…
Early-time millimeter observations of the nearby Type II SN 2024ggi
Maokai Hu, Yiping Ao, Yi Yang +4
The short-lived ionized emission lines in early spectroscopy of the nearby type II supernova SN 2024ggi signify the presence of dense circumstellar matter (CSM) close to its progen…
The environmental dependence of Spitzer dusty Supernovae
Lin Xiao, Tamás Szalai, Lluís Galbany +9
Thanks to the mid-infrared capability offered by Spitzer, systematic searches of dust in SNe have been carried out over the past decade. Studies have revealed the presence of a sub…
A Shock Flash Breaking Out of a Dusty Red Supergiant
Gaici Li, Maokai Hu, Wenxiong Li +41
Shock breakout emission is light that arises when a shockwave, generated by core-collapse explosion of a massive star, passes through its outer envelope. Hitherto, the earliest det…
