Direct Collapse Pre-supermassive Black Hole Objects as Ly Emitters
Yang Luo, Isaac Shlosman
The Direct Collapse scenario to form the supermassive black hole (SMBH) seeds offers the most promising way to explain the origin of quasars at . Assuming atomic primordial ga…
Numerical modeling the mass feeding rates onto accretion-modified stars embedded within AGN disks
Yang Luo, Jian-Min Wang
Accretion disks surrounding supermassive black holes can potentially form stars within the self-gravitating region. These stars undergo high accretion rates because of the dense en…
Nuclear burning in an accretion flow around a stellar-mass black hole embedded within an AGN disk
Zifan Tang, Yang Luo, Jian-Min Wang
A stellar-mass black hole, embedded within the accretion disk of an active galactic nuclei (AGN), has the potential to accrete gas at a rate that can reach approximately $\sim 10^9…
Direct Collapse Accretion Disks Within Dark Matter Halos: Saturation of the Magnetorotational Instability and the Field Expulsion
Yang Luo, Isaac Shlosman
We have used high-resolution zoom-in simulations of direct collapse to supermassive black hole (SMBH) seeds within dark mater (DM) halos in the presence of magnetic fields generate…
Low- and High-velocity \ion{O}{6} in Milky Way-like Galaxies: the Role of Stellar Feedback
Zhijie Zhang, Xiaoxia Zhang, Hui Li +7
Milky Way-type galaxies are surrounded by a warm-hot gaseous halo containing a considerable amount of baryons and metals. The kinematics and spatial distribution of highly-ionized…
Direct Collapse to Precursors of Supermassive Black Hole Seeds:Radiation-feedback-generated Outflows
Yang Luo, Isaac Shlosman, Kentaro Nagamine
We use high-resolution zoom-in cosmological simulations to model outflow triggered by radiation and thermal drivers around the central mass accumulation during direct collapse with…
Hot subdwarfs from the surviving companions of the white dwarf + main-sequence channel of Type Ia supernovae
Xiangcun Meng, Yangpin Luo
Some surviving companions of type Ia supernovae (SNe Ia) from the white-dwarf + main-sequence (WD + MS) channel may evolve to hot subdwarfs. In this paper, we preformed stellar evo…
Direct collapse to supermassive black hole seeds: the critical conditions for suppression of cooling
Yang Luo, Isaac Shlosman, Kentaro Nagamine +1
Observations of high-redshift quasars imply the presence of supermassive black holes already at z~ 7.5. An appealing and promising pathway to their formation is the direct collapse…
Direct Collapse to Supermassive Black Hole Seeds with Radiation Transfer: Cosmological Halos
Kazem Ardaneh, Yang Luo, Isaac Shlosman +3
We have modeled direct collapse of a primordial gas within dark matter halos in the presence of radiative transfer, in high-resolution zoom-in simulations in a cosmological framewo…
XMM-Newton Survey of Local OVII Absorption Lines in the Spectra of Galactic X-ray Sources
Yang Luo, Taotao Fang, Renyi Ma
The detection of highly ionized metal absorption lines in the X-ray spectra of the Galactic X-ray binaries (XRBs) implies the distribution of hot gas along the sightline toward the…
Direct Collapse to Supermassive Black Hole Seeds with Radiative Transfer: Isolated Halos
Yang Luo, Kazem Ardaneh, Isaac Shlosman +3
Direct collapse within dark matter (DM) halos is a promising path to form supermassive black hole (SMBH) seeds at high redshifts. The outer part of this collapse remains optically…
Direct Collapse to Supermassive Black Hole Seeds: Comparing the AMR and SPH Approaches
Yang Luo, Kentaro Nagamine, Isaac Shlosman
We provide detailed comparison between the AMR code Enzo-2.4 and the SPH/N- body code GADGET-3 in the context of isolated or cosmological direct baryonic collapse within dark matte…
On the Origin of Highly Ionized X-ray Absorbers Detected in the Galactic X-ray Binaries
Yang Luo, Taotao Fang
X-ray observations of the Galactic X-ray binaries (XRB) revealed numerous highly ionized metal absorption lines. However, it is unclear whether such lines are produced by the hot i…
Neutrino-cooled Accretion Model with Magnetic Coupling for X-ray Flares in GRBs
Yang Luo, Wei-Min Gu, Tong Liu +1
The neutrino-cooled accretion disk, which was proposed to work as the central engine of gamma-ray bursts, encounters difficulty in interpreting the X-ray flares after the prompt ga…
