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…
A Persistently Active Fast Radio Burst source Embedded in an Expanding Supernova Remnant
Chen-Hui Niu, Di Li, Yuan-Pei Yang +21
Fast radio bursts (FRBs) remain one of the most puzzling astrophysical phenomena. While most FRBs are detected only once or sporadically, we present the identification of FRB 20190…
Super-Orbital Variations in Magnetar Rotation Measure Arising from the Precession of Companion Star: Implications for FRB 20220529
Ze-Xin Du, Yun-Wei Yu, Aming Chen +2
Recent observations of FRB 20220529 reveal significant variation and a partial reversal in its rotation measure (RM), suggesting the presence of a dynamically evolving magnetized e…
TransFit-CSM: A Fast, Physically Consistent Framework for Interaction-Powered Transients
Yu-Hao Zhang, Liang-Duan Liu, Ze-Xin Du +3
We present TransFit-CSM, a fast and physically consistent framework for modeling interaction-powered transients. The method self-consistently couples the ejecta circumstellar mediu…
TransFit: An Efficient Framework for Transient Light-Curve Fitting with Time-Dependent Radiative Diffusion
Liang-Duan Liu, Yu-Hao Zhang, Yun-Wei Yu +4
Modeling the light curves (LCs) of luminous astronomical transients, such as supernovae, is crucial for understanding their progenitor physics, particularly with the exponential gr…
