Radio flares and X-ray hardening embedded in the long soft state of 4U 1543-475
Zuobin Zhang, Rob Fender, Jiachen Jiang +14
We present a comprehensive multi-wavelength study of the black hole X-ray binary 4U 1543-475 during its 2021 outburst, focusing on radio flaring episodes that are commonly interpre…
The Homogeneous MeerKAT and Swift/XRT X-ray Binary Radio:X-ray Plane
Justine Crook-Mansour, Rob Fender, Andrew Hughes +22
During the hard and quiescent spectral states in X-ray binaries, a non-linear correlation is observed between radio and X-ray luminosities, providing a valuable tool to probe the c…
Jets from a stellar-mass black hole are as relativistic as those from supermassive black holes
Xian Zhang, Wenfei Yu, Francesco Carotenuto +15
Relativistic jets from supermassive black holes in active galactic nuclei are amongst the most powerful phenomena in the universe, acting to regulate the growth of massive galaxies…
Simultaneous multi-wavelength observations of the repeating fast radio burst FRB 20190520B with Swift and FAST
Zhen Yan, Wenfei Yu, Kim L. Page +8
Among several dozen known repeating Fast radio bursts (FRBs), those precisely localized offer the best opportunities to explore their multi-wavelength counterparts, which are key t…
A flaring radio counterpart to a fast radio burst reveals a newborn magnetized engine
Xian Zhang, Wenfei Yu, Zhen Yan +2
Fast Radio Bursts (FRBs) are energetic millisecond radio bursts at cosmological distances, whose underlying engine is not identified. Among a sub-population that emit repeated radi…
Flaring gamma-ray emission coincident with a hyperactive fast radio burst source
Yi Xing, Wenfei Yu, Zhen Yan +2
Fast radio bursts (FRBs) are bright milliseconds-duration radio bursts from cosmological distances. Despite intense observational and theoretical studies, their physical origin is…
