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…
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…
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…
StarWhisper Telescope: An AI framework for automating end-to-end astronomical observations
Cunshi Wang, Yu Zhang, Yuyang Li +25
The exponential growth of large-scale telescope arrays has boosted time-domain astronomy development but introduced operational bottlenecks, including labor-intensive observation p…
Artificial Satellite Trails Detection Using U-Net Deep Neural Network and Line Segment Detector Algorithm
Xiaohan Chen, Hongrui Gu, Cunshi Wang +6
With the rapid increase in the number of artificial satellites, astronomical imaging is experiencing growing interference. When these satellites reflect sunlight, they produce stre…
FALCO: a Foundation model of Astronomical Light Curves for time dOmain astronomy
Xiaoxiong Zuo, Yihan Tao, Yang Huang +13
Time-domain surveys have advanced astronomical research by revealing diverse variable phenomena, from stellar flares to transient events. The scale and complexity of survey data, a…
