Spectral Dataset of Stripped-Envelope Supernovae from the Tsinghua Supernova Group
Danfeng Xiang, Xiaofeng Wang, Jujia Zhang +40
The extent of envelope stripping in the progenitor stars is directly reflected in the diversity of spectral features observed in stripped-envelope supernovae (SESNe). Through exten…
SN 2024abvb: A Type Icn Supernova in the Outskirts of its Host Galaxy
Maokai Hu, Shengyu Yan, Xiaofeng Wang +11
We present multiband photometric and spectroscopic observations of supernova (SN) 2024abvb, which exhibits early-time prominent photoionized narrow emission lines of C II superpose…
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…
AT 2024wpp: the most luminous fast-evolving optical transient linked to the merger explosion of a black-hole binary
Jialian Liu, Bao Wang, Xiaofeng Wang +48
Fast blue optical transients (FBOTs) represent one of the most exotic astrophysical transients, exhibiting unusually strong emission across X-ray, optical, and radio wavelengths. T…
SN 2022acko: a low-luminosity SNe IIP with signs of early circumstellar interaction
Lin Han, Zhang Jujia, Wang Xiaofeng +13
We present optical-ultraviolet photometry and optical spectra for the type II supernova (SN) 2022acko. The spectroscopic observations span phases from 1.5 to 60 days…
SN 2024iss: A Double-peaked Type IIb Supernova with Evidence of Circumstellar Interaction
Liyang Chen, Xiaofeng Wang, Qinyu Wu +54
We present optical, ultraviolet, and X-ray observations of supernova (SN) 2024iss, a Type IIb SN that shows a prominent double-peaked light curve. We modeled the first peak with a…
