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…
Evidence of Long-Lived Powerful Gyrosynchrotron Radio Emission in the Close Binary FF UMa
Ruijie Gao, Jun Yang, Yang Gao +7
RS Canum Venaticorum (RS CVn) close binaries, characterized by tidal locking, rapid rotations, and strong magnetic fields, are ideal laboratories for high-resolution radio observat…
VLBI astrometry of radio stars to link radio and optical celestial reference frames - II. 11 radio stars
Jingdong Zhang, Bo Zhang, Shuangjing Xu +10
The alignment between the radio-based International Celestial Reference Frame (ICRF) and the optical Gaia Celestial Reference Frame (Gaia-CRF) is critical for multi-waveband astron…
Validating the bright Gaia celestial reference frame with new VLBI astrometry of radio stars
Jingdong Zhang, Bo Zhang, Shuangjing Xu +1
There exist inconsistencies between the bright and faint Gaia Celestial Reference Frame 3 (Gaia-CRF3), which manifests as a systematic rotation and needs to be independently estima…
