Spectral Energy Distribution of the inner accretion flow around Sgr A* -- Clue for a weak outflow in the innermost region
Ren-Yi Ma, Shawn R. Roberts, Ya-Ping Li +1
Sgr A* represents a unique laboratory for the detailed study of accretion processes around a low-luminosity supermassive black hole (SMBH). Recent X-ray observations have allowed f…
Numerical study of active galactic nucleus feedback in an elliptical galaxy with {\it MACER}
Feng Yuan, Jeremiah P. Ostriker, DooSoo Yoon +5
This paper summarizes our recent works of studying AGN feedback in an isolated elliptical galaxy by performing high-resolution hydrodynamical numerical simulations. Bondi radius is…
Reconciling the Quasar Microlensing Disc Size Problem with a Wind Model of Active Galactic Nucleus
Ya-Ping Li, Feng Yuan, Xinyu Dai
Many analyses have concluded that the accretion disc sizes measured from the microlensing variability of quasars are larger than the expectations from the standard thin disc theory…
Active Galactic Nuclei Feedback in an Elliptical Galaxy with the Most Updated AGN Physics (II): High-Angular Momentum Case
Doosoo Yoon, Feng Yuan, Zhao-Ming Gan +3
This is the second paper of our series of works of studying the effects of active galactic nuclei (AGN) feedback on the cosmological evolution of an isolated elliptical galaxy by p…
Stellar and AGN feedback in isolated early-type galaxies: the role in regulating star formation and ISM properties
Ya-Ping Li, Feng Yuan, Houjun Mo +6
Understanding how galaxies maintain the inefficiency of star formation with physically self-consistent models is a central problem for galaxy evolution. Although numerous theoretic…
The Profiles of Fe Kα Line From the Inhomogeneous Accretion Flow
Xiao-Di Yu, Ren-Yi Ma, Ya-Ping Li +2
The clumpy disc, or inhomogeneous accretion flow, has been proposed to explain the properties of accreting black hole systems. However, the observational evidences remain to be exp…
