A Jet from a Nearly Dormant Black Hole
Xiaopeng Cheng, Hai Yang, Jun Yang +11
Most galaxies host supermassive black holes (SMBHs) that remain weakly accreting or dormant for much of their lifetimes. At the lowest accretion rates, these systems may represent…
Impacts of radiative cooling on the images of a black hole shadow and extended jets in two-temperature GRMHD simulations
Mingyuan Zhang, Yosuke Mizuno, Indu K. Dihingia +4
The recent 230 GHz observations from the Event Horizon Telescope collaboration have successfully imaged the supermassive black hole shadow of the M87 galaxy. However, the relativel…
Wind from the Hot Accretion Flow and Super-Eddington Accretion Flow
Hai Yang, Feng Yuan
Wind is believed to be widespread in various black hole accretion flows. However, unlike the wind from thin disks, which have substantial observational evidence, the wind from hot…
Modeling the inner part of the jet in M87: Confronting jet morphology with theory
Hai Yang, Feng Yuan, Hui Li +7
The formation of jets in black hole accretion systems is a long-standing problem. It has been proposed that a jet can be formed by extracting the rotation energy of the black hole…
A ring-like accretion structure in M87 connecting its black hole and jet
Ru-Sen Lu, Keiichi Asada, Thomas P. Krichbaum +118
The nearby radio galaxy M87 is a prime target for studying black hole accretion and jet formation^{1,2}. Event Horizon Telescope observations of M87 in 2017, at a wavelength of 1.3…
The properties of wind and jet from a super-Eddington accretion flow around a supermassive black hole
Hai Yang, Feng Yuan, Tom Kwan +1
Wind and jet are important medium of AGN feedback thus it is crucial to obtain their properties for the feedback study. In this paper we investigate the properties of wind and jet…
Modeling the inner part of M87 jet: confronting jet morphology with theory
Hai Yang, Feng Yuan, Hui Li +5
The formation of jets in black hole accretion systems is a long-standing problem. It has been proposed that a jet can be formed by extracting the rotation energy of the black hole…
Formation of episodic jets and associated flares from black hole accretion systems
Miljenko Cemeljic, Hai Yang, Feng Yuan +1
Episodic ejections of blobs (episodic jets) are widely observed in black hole sources and usually associated with flares. In this paper, by performing and analyzing three dimension…
The Accretion flow in M87 is really MAD
Feng Yuan, Haiyang Wang, Hai Yang
The supermassive black holes in most galaxies in the universe are powered by hot accretion flows. Both theoretical analysis and numerical simulations have indicated that, depending…
Numerical simulation of hot accretion flows (IV): effects of black hole spin and magnetic field strength on the wind and the comparison between wind and jet properties
Hai Yang, Feng Yuan, Ye-fei Yuan +1
This is the fourth paper of our series of works studying winds from hot accretion flows around black holes. In the first two papers, we have shown the existence of strong winds in…
Flux ropes in SANE disks
Miljenko Čemeljić, Feng Yuan, Hai Yang
Three-dimensional numerical simulations of a hot accretion flow around a supermassive black hole are performed using the general relativity magneto-hydrodynamic (GRMHD) code Athena…
