Multiwavelength Analysis of the Einstein Probe X-ray Transient EP240305a
Ruican Ma, Ye Li, Lian Tao +32
We report multiwavelength observations of EP240305a, an uncatalogued X-ray transient detected by the Einstein Probe on March 5, 2024. The source exhibits distinct characteristics a…
Hydrodynamical simulation of wind production from hot accretion flows in tidal disruption events
Mingjun Liu, De-Fu Bu, Xiao-Hong Yang +5
Wind is a key mechanism for supermassive black hole (SMBH) feedback to their host galaxies. In tidal disruption events (TDEs), black holes spend most of their time accreting at hig…
Minutes-long soft X-ray prompt emission from a compact object merger
An Li, Chen-Wei Wang, Niccolò Passaleva +78
Compact object mergers are multi-messenger sources and known progenitors of some gamma-ray bursts, bright flashes of high-energy radiation powered by a central engine, either an ac…
A fast powerful X-ray transient from possible tidal disruption of a white dwarf
Dongyue Li, Wenda Zhang, Jun Yang +97
Stars captured by black holes (BHs) can be torn apart by strong tidal forces, producing electromagnetic flares. To date, more than 100 tidal disruption events (TDEs) have been obse…
Multiwavelength Observations of the Apparently Non-repeating FRB 20250316A
Ye Li, Hui Sun, Lei Qian +72
The physical origin of fast radio bursts (FRBs) remains uncertain. Although multiwavelength observations have been widely conducted, only Galactic FRB~20200428D is associated with…
EP241021a: a months-duration X-ray transient with luminous optical and radio emission
Shu Xinwen, Yang Lei, Yang Haonan +82
We present the discovery of a peculiar X-ray transient, EP241021a, by the Einstein Probe (EP) mission, and the results from multiwavelength follow-up observations. The transient wa…
