SN 2025fhm: A central-engine powered Ic-BL supernova associated with X-ray transient EP250304a
Cui-Ying Song, Nan Jiang, Xiaofeng Wang +32
We present X-ray, optical, and radio follow-up observations of EP250304a, an extragalactic fast X-ray transient (EFXT) discovered by the Einstein Probe. Its X-ray light curve exhib…
Early Near-Infrared Excess and Rapid Disk-Corona Evolution in the Tidal Disruption Event 2024aepd
Yongxin Wu, Yanan Wang, Thomas M. Reynolds +38
We present multi-wavelength observations of the tidal disruption event (TDE) 2024aepd, spanning primarily the first 300 days after discovery. A prominent near-infrared (NIR)…
Coupled Shock Cooling and Radioactive Heating in the Type IIb Supernova SN 2024aecx: An Extended Envelope and Rapid Optical Decline
Na Wei, Yu-Hao Zhang, Liang-Duan Liu +4
SN~2024aecx is a nearby, rapidly evolving stripped-envelope supernova with a prominent double-peaked ultraviolet--optical light curve. We model its multiband evolution with an exte…
X-rays breaking out of pre-explosion ejecta mark a supernova's first light
Weimin Yuan, Qiu-Ju Huang, Jin-Ping Zhu +130
Massive stars die as core-collapse supernovae, whose optical light emerges days after the implosion. Theory predicts that the initial collapse-driven shock, upon breaking through t…
Not All Who Wander Are Lost: Early Excess Demographics in the Volume-limited ZTF DR2 SN Ia Sample
César Rojas-Bravo, Ning-Chen Sun, Mathew Smith +7
Early-time flux excesses in Type Ia supernovae (SNe~Ia) offer a unique insight into their progenitor systems and explosion mechanisms. Although individual early-excess events and l…
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 2024abfl: A Low-Luminosity Type IIP Supernova in NGC 2146 from a Low-Mass Red Supergiant Progenitor
Xiaohan Chen, Ning-Chen Sun, Qiang Xi +44
Type IIP supernovae (SNe IIP) exhibit a significant diversity in their explosion properties, yet the physical mechanisms driving this diversity remain unknown. In this work, we pre…
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…
Revealing the diversity of Type IIn supernova progenitors through their environments
Zexi Niu, Ning-Chen Sun, Emmanouil Zapartas +4
Type IIn supernovae (SNe IIn) are hydrogen-rich explosions embedded in dense circumstellar medium (CSM), which gives rise to their characteristic narrow hydrogen emission lines. Th…
SN 2025coe: A Multiple-Peaked Calcium-Strong Transient from A White-Dwarf Progenitor
Chun Chen, Ning-Chen Sun, Qiang Xi +25
SN 2025coe is a calcium-strong transient located at an extremely large projected offset 39.3 kpc from the center of its host, the nearby early-type galaxy NGC 3277 at a dista…
An environmental analysis of supernova iPTF13bvn with HST and MUSE
Adam J. Singleton, Justyn R. Maund, Ning-Chen Sun
Searches for supernovae (SNe) progenitors have relied on a direct detection of the star in fortuitous pre-explosion images. We propose an alternative method, using a combination of…
Discovery of a variable yellow supergiant progenitor for the Type IIb SN 2024abfo
Zexi Niu, Ning-Chen Sun, Justyn R. Maund +4
We report the discovery of a progenitor candidate for the Type~IIb SN2024abfo using multi-epoch pre-explosion images from the Hubble Space Telescope and the Dark Energy Camera Lega…
Signatures of the Shock Interaction as an Additional Power Source in the Nebular Spectra of SN 2023ixf
Amit Kumar, Raya Dastidar, Justyn R. Maund +2
Red supergiants may lose significant mass during the final 100-1000 years before core collapse, shaping their circumstellar environment. The supernova (SN) shockwave propagating th…
Exclusion of a direct progenitor detection for the Type Ic SN 2017ein based on late-time observations
Yi-Han Zhao, Ning-Chen Sun, Junjie Wu +7
To date, SN 2017ein is the only Type Ic supernova with a directly identified progenitor candidate. This candidate points to a very massive (45 ) Wolf-Rayet progenitor,…
Discovery of a dusty yellow supergiant progenitor for the Type IIb SN 2017gkk
Zexi Niu, Ning-Chen Sun, Jifeng Liu
Type IIb supernovae are important subclass of stripped-envelope supernovae (SNe), which show H lines only at early times. Their progenitors are believed to contain a low-mass H env…
The disappearance of the blue and luminous progenitor of the Type IIn SN 2010jl
Zexi Niu, Ning-Chen Sun, Jifeng Liu
Type IIn supernovae (SNe) exhibit narrow hydrogen lines that arise from the strong interaction between ejecta and circumstellar material. It remains poorly understood, however, wha…
