SN 2022erq: A Superluminous Thermonuclear Supernova with Escalating Preexplosion Mass Loss
Qian Zhai, Jujia Zhang, Xiaofeng Wang +51
We present a photometric and spectroscopic study of the superluminous Type Ia supernova SN 2022erq. Its early spectra, dominated by iron-group elements with weak intermediate-mass…
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…
Automated Identification of the Tip of the Red Giant Branch in Globular Clusters with Gaia Data
Yi Yang, Zhenzhen Shao, Xiaofeng Wang +1
This study introduces an automated approach for identifying the tip of the red giant branch (TRGB) in globular clusters, combining astronomical data with algorithmic methods. Using…
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…
A binary merger product as the direct progenitor of a Type II-P supernova
Zexi Niu, Ning-Chen Sun, Emmanouil Zapartas +16
Type II-P supernovae (SNe II-P) are the most common class of core-collapse SNe in the local Universe and play critical roles in many aspects of astrophysics. Since decades ago theo…
The Double-Peaked Calcium-Strong SN 2025coe: Progenitor Constraints from Early Interaction and Ejecta Asymmetries
Aravind P. Ravi, Sahana Kumar, Raphael Baer-Way +47
Supernova (SN) 2025coe at a distance of 25 Mpc is the second-closest calcium-strong (CaST) transient. It was discovered at a large projected offset of 34 kpc from its p…
SN 2024gy: Multi-epoch Spectroscopic Features Suggestive of Delayed Detonation in a Type Ia Supernova
Liping Li, Zhenyu Wang, Jialian Liu +28
We present photometric and spectroscopic observations of SN 2024gy, a Type Ia supernova (SN Ia) exhibiting high-velocity features (HVFs) in its early-time spectra. This SN reaches…
Optical and Near-infrared Observations of SN 2023ixf for over 600 days after the Explosion
Gaici Li, Xiaofeng Wang, Yi Yang +37
Context.We present a comprehensive photometric and spectroscopic study of the nearby Type II supernova (SN) 2023ixf, with our extensive observations spanning the phases from ~3 to…
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…
