Probing the Shock Breakout Signal of SN 2024ggi from the Transformation of Early Flash Spectroscopy
Jujia Zhang, Luc Dessart, Xiaofeng Wang +11
We present early-time, hour-to-day cadence spectroscopy of the nearby type II supernova (SN II) 2024ggi, which was discovered at a phase when the SN shock just emerged from the red…
SN 2021dbg: A Luminous Type IIP-IIL Supernova Exploding from a Massive Star with a Layered Shell
Zeyi Zhao, Jujia Zhang, Liping Li +9
We present extensive observations and analysis of supernova (SN) 2021dbg, utilizing optical photometry and spectroscopy. For approximately 385 days following the explosion, SN 2021…
A closer look at the host-galaxy environment of high-velocity Type Ia supernovae
Han-Tang Lin, Yen-Chen Pan, Abdurro'uf
Recent studies suggested that the ejecta velocity of Type Ia supernova (SN Ia) is a promising indicator in distinguishing the progenitor systems and explosion mechanisms. By classi…
The Red Supergiant Progenitor of Type II Supernova 2024ggi
Danfeng Xiang, Jun Mo, Xiaofeng Wang +8
We present a detailed analysis of the progenitor and its local environment for the recently discovered type II supernova (SN) 2024ggi at a distance of about 6.7~Mpc, by utilizing t…
A spectral data release for 104 Type II Supernovae from the Tsinghua Supernova Group
Han Lin, Xiaofeng Wang, Jujia Zhang +33
We present 206 unpublished optical spectra of 104 type II supernovae obtained by the Xinglong 2.16m telescope and Lijiang 2.4m telescope during the period from 2011 to 2018, spanni…
