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
The paper models the double-peaked light curve of the Type IIb supernova SN 2024aecx by combining early shock‑cooling emission with later radioactive heating in a time‑dependent ra…
Fast Optical Variability of the TeV Blazar PKS 1725+123 Observed by SVOM-VT and Insights from Multi-wavelength Follow-up Observations
Shuo-Yu Liu, Yu-Wei Yu, Ji-Shun Lian +29
PKS 1725+123 is a flat-spectrum radio quasar (FSRQ) with a redshift of . The detection of this object in the TeV band was reported by the MAGIC telescopes and H.E.S.S. in…
Radio eclipse of the slowest spinning Galactic-field spider pulsar PSR J1932+2121 and its X-ray emission prospect
Ze-Xin Du, Yun-Wei Yu, Zong-Lin Yang +5
PSR J19322121 is a newly discovered spider pulsar with a pronounced radio eclipse identified by the Five-hundred-meter Aperture Spherical radio Telescope (FAST); it provides an…
\texttt{TransFit-MAG}: Self-Consistent Modeling of Magnetar-Powered Transients from Shock Breakout to Spin-Down Heating
Jing-Yao Li, Liang-Duan Liu, Yun-Wei Yu +2
Magnetar engines are widely invoked to power luminous optical transients, but their early emission depends on the coupled evolution of engine injection, shock heating, adiabatic co…
Flux Variations of Fast Radio Bursts and Their Persistent Radio Sources: Evidence for a Shared Progenitor
Xinming Li, Chenhui Niu, Jiaheng Zhang +24
Fast radio bursts (FRBs) are millisecond-duration extragalactic radio transients, some of which are associated with compact persistent radio sources (PRSs), hinting at a physical c…
An Attempt to Search for Unintended Electromagnetic Radiation from Starlink Satellites with the 21 Centimeter Array: Methodology and RFI Characterization
Xupiao Yang, Qijun Zhi, Yanbin Yang +6
The rapid expansion of low-Earth-orbit (LEO) megaconstellations introduces new risks to radio astronomy from unintended electromagnetic radiation (UEMR). In this work, we present a…
