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…
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…
Cool-Core Destruction in Merging Clusters with AGN Feedback and Radiative Cooling
Shuang-Shuang Chen, Hsiang-Yi Karen Yang, Hsi-Yu Schive +3
The origin of cool-core (CC) and non-cool-core (NCC) dichotomy of galaxy clusters remains uncertain. Previous simulations have found that cluster mergers are effective in destroyin…
A fast powerful X-ray transient from possible tidal disruption of a white dwarf
Dongyue Li, Wenda Zhang, Jun Yang +97
Stars captured by black holes (BHs) can be torn apart by strong tidal forces, producing electromagnetic flares. To date, more than 100 tidal disruption events (TDEs) have been obse…
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…
A magnetic white dwarf formed through a binary merger within 35 million years
Huahui Yan, Jiamao Lin, Rizhong Zheng +15
White dwarfs (WDs) represent the final evolutionary stage of most stars, typically originating from progenitor stars with masses below approximately 8 to 10 …
