Evolution of accretion disk and corona during outbursts in black hole binary systems is still unclear. Here, the authors show spectral analysis of MAXI J1820+070 and propose a scenario of a dynamical corona to explain the evolution of the reflection

Quasars are high-luminosity active galactic nuclei believed to be powered by accretion of interstellar matter onto a super-massive black hole (SMBH) therein. Most of the observed energy is released in an accretion disk of inspiralling gas surrounding

On the Black Hole Mass---X-ray Excess Variance Scaling Relation for Active Galactic Nuclei in the Low-mass Regime

Autor: Xin-Lin Zhou, Hai-Wu Pan, Xiao-Bo Dong, Weimin Yuan, Bifang Liu

Recent studies of active galactic nuclei (AGN) found a statistical inverse linear scaling between the X-ray normalized excess variance $\sigma_{\rm rms}^2$ (variability amplitude) and the black hole mass spanning over $M_{\rm BH}=10^6- 10^9\ M_{\odot

Spectra from a Magnetic Reconnection–heated Corona in Active Galactic Nuclei

Autor: Ken Ohsuga, Shin Mineshige, Bifang Liu

Publikováno v: The Astrophysical Journal. 587:571-579

We investigate a corona coupled with underlying disk through magnetic field and radiation field, and present emergent spectra calculated from Monte Carlo simulations. The spectra are determined for given black-hole mass and accretion rate. We find tw

A Simple Model for a Magnetic Reconnection–heated Corona

Autor: Kazunari Shibata, Shin Mineshige, Bifang Liu

Publikováno v: The Astrophysical Journal. 572:L173-L176

We construct a simple model for a magnetic reconnection heated corona above a thin accretion disk in AGNs and Galactic black hole candidates(GBHCs). The basic assumptions are that (1) the magnetic reconnection heat is cooled down overwhelmingly by Co
