Magnetically Arrested Discs Powering Jets in a Large Sample of Low-Accretion FR I Radio Galaxies
Huibo Fei, Han He, Bei You +4
We study a sample of 289 Fanaroff-Riley type I (FR I) radio galaxies selected from the LOFAR Two-Metre Sky Survey (LoTSS) DR1, identified by their edge-darkened radio morphologies.…
Dynamic disk-corona coupling during the state transition of Swift J1727.8-1613
Han He, Yi Long, Bei You +4
State transitions during outbursts of black hole X-ray binaries exhibit complex, rapidly evolving disk-corona coupling. Understanding this dynamic phase is essential for decipherin…
Radiation Pressure Instability in the "turn-on" Changing-Look AGN SDSS J1430+2303
Han He, Bei You, Marzena Åniegowska +1
We present a multi-wavelength study of the changing-look AGN SDSS J1430+2303. The optical flux increased by an order of magnitude over four years, driving a spectral transition fro…
QPEs from Warped Disk Collisions with EMRIs: Brightness-Recurrence Diagram and Gravitational-Wave Follow-up
Bo-An Chen, Bei You, Giovanni Miniutti +11
Quasi-Periodic Eruptions (QPEs) display correlated long/short and strong/weak patterns that remain unexplained by existing flat-disk collision models. We propose that these feature…
On the optical emission in the mini-outburst of the black hole X-ray binary MAXI J1348-630
Xiao Fan, Bei You, Dizhan Du +2
We investigate the optical emission of the black hole X-ray binary MAXI J1348-630 during its 2019 minioutburst. Using optical data from the Las Cumbres Observatory Global Telescope…
Temporal evolution of quasi-periodic oscillations in an accreting black hole Swift J1727.8-1613: coevolution of the disk-corona during the state transition
Sai-En Xu, Bei You, Yi Long +1
Low-frequency quasi-periodic oscillations (QPOs) are commonly observed in black hole X-ray binaries, and their frequency has been found to correlate with various spectral propertie…
