SN 2023fyq: direct detection of a Type Ibn supernova progenitor and its multi-wavelength environmental constraints
Xinyi Hong, Ning-Chen Sun, Yali Shao +9
Context. Type Ibn supernovae (SNe) are characterized by narrow helium emission lines arising from ejecta-circumstellar medium interaction, yet their progenitors remain debated, wit…
A statistical study of the environmental age of core-collapse supernovae based on VLT/MUSE integral-field-unit spectroscopy
Qiang Xi, Ning-Chen Sun, Yihan Zhao +13
We aim to understand the progenitor channels of CCSNe via a statistical study of the ages of their environments. We compiled a large and minimally biased sample of 128 CCSNe discov…
Direct Detection of Type II-P Supernova Progenitors with the and CSST Surveys
Junjie Wu, Ning-Chen Sun, Zexi Niu +14
Identifying and characterizing supernova (SN) progenitor stars remains a central yet difficult goal in SN research, limited by archival images lacking sufficient depth or spatial r…
SN 2024aecx: a fast-evolving Type IIb supernova with a prominent shock-cooling peak
Qiang Xi, Ning-Chen Sun, David Aguado +36
SN 2024aecx is a nearby (11 Mpc) Type IIb SN discovered within 1 d after explosion. In this paper we report high-cadence photometric (typically 0.51 day) and spec…
Constraining the progenitor of the nearby Type II-P SN 2024ggi with environmental analysis
Xinyi Hong, Ning-Chen Sun, Zexi Niu +3
The progenitors of Type II-P supernovae (SN) have been confirmed to be red supergiants. However, the upper mass limit of the directly probed progenitors is much lower than that pre…
Derivative Spectroscopy and its Application at Detecting the Weak Emission/Absorption Lines
Lihuan Yu, Jiangdan Li, Jinliang Wang +4
The development of spectroscopic survey telescopes like Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST), Apache Point Observatory Galactic Evolution Experiment a…
