The universal "heartbeat" oscillations in black hole systems accross the mass-scale
Qingwen Wu, Bozena Czerny, Mikolaj Grzedzielski +7
The hyperluminous X-ray source (HLX-1, the peak X-ray luminosity ) near the spiral galaxy ESO 243-49 is possibly the best candidate for intermediate ma…
Modified viscosity in accretion disks. Application to Galactic black hole binaries, intermediate mass black holes and AGN
Mikołaj Grzędzielski, Agnieszka Janiuk, Bożena Czerny +1
Black holes (BHs) surrounded by accretion disks are present in the Universe at different scales of masses, from microquasars up to the active galactic nuclei (AGNs). The current pi…
On the origin of the HLX-1 outbursts
Mouyuan Sun, Wei-Min Gu, Zhen Yan +2
HLX-1, currently the best intermediate-mass black hole candidate, has undergone seven violent outbursts, each with a peak X-ray luminosity of $L_{\mathrm{peak},\mathrm{X}}\sim 10^{…
An accretion-jet model for M87: interpreting the spectral energy distribution and Faraday rotation measure
Jianchao Feng, Qingwen Wu, Ru-Sen Lu
M87 is arguably the best supermassive black hole (BH) to explore the jet and/or accretion physics due to its proximity and fruitful high-resolution multi-waveband observations. We…
On the origin of the soft photons of the high synchrotron peaked blazar : PKS 1424+240
Shiju Kang, Yong-Gang Zheng, Qingwen Wu +1
PKS 1424+240 is a distant very high energy gamma-ray BL Lac object with redshift . It was found that pure synchrotron self-Compton (SSC) process normally need extreme inpu…
