The Diverse Morphology, Stellar Population, and Black Hole Scaling Relations of the Host Galaxies of Nearby Quasars
Yulin Zhao, Luis C. Ho, Jinyi Shangguan +3
We present rest-frame and imaging of 35 low-redshift () Palomar-Green quasars using the Hubble Space Telescope Wide Field Camera 3. We perform multi-component two-…
Barred Galaxies in the IllustrisTNG Simulation
Dongyao Zhao, Min Du, Luis C. Ho +2
Almost two-thirds of disk galaxies in the local universe host bars, which serve as important drivers of secular evolutionary processes. While cosmological simulations are powerful…
Orbital distribution of infalling satellite halos across cosmic time
Zhao-Zhou Li, Dong-Hai Zhao, Y. P. Jing +2
The initial orbits of infalling subhalos largely determine the subsequent evolution of the subhalos and satellite galaxies therein and shed light on the assembly of their hosts. Us…
Kinematic decomposition of IllustrisTNG disk galaxies: morphology and relation with morphological structures
Min Du, Luis C. Ho, Victor P. Debattista +4
We recently developed an automated method, auto-GMM to decompose simulated galaxies. It extracts kinematic structures in an accurate, efficient, and unsupervised way. We use auto-G…
A New Channel of Bulge Formation via The Destruction of Short Bars
Minghao Guo, Min Du, Luis C. Ho +2
Short (inner) bars of sub-kiloparsec radius have been hypothesized to be an important mechanism for driving gas inflows to small scales, thus feeding central black holes. Recent nu…
Identifying kinematic structures in simulated galaxies using unsupervised machine learning
Min Du, Luis C. Ho, Dongyao Zhao +4
Galaxies host a wide array of internal stellar components, which need to be decomposed accurately in order to understand their formation and evolution. While significant progress h…
The Role of Major Mergers and Nuclear Star Formation in Nearby Obscured Quasars
Dongyao Zhao, Luis C. Ho, Yulin Zhao +2
We investigate the triggering mechanism and the structural properties of obscured luminous active galactic nuclei from a detailed study of the rest-frame and HST images of…
Determination of Dark Matter Halo Mass from Dynamics of Satellite Galaxies
Zhao-Zhou Li, Y. P. Jing, Yong-Zhong Qian +2
We show that the mass of a dark matter halo can be inferred from the dynamical status of its satellite galaxies. Using 9 dark-matter simulations of halos like the Milky Way (MW), w…
Exploring the progenitors of brightest cluster galaxies at z~2
Dongyao Zhao, Christopher J. Conselice, Alfonso Aragón-Salamanca +5
We present a new method for tracing the evolution of BCGs from to . We conclude on the basis of semi-analytical models that the best method to select BCG progeni…
Evolution of the brightest cluster galaxies: the influence of morphology, stellar mass and environment
Dongyao Zhao, Alfonso Aragón-Salamanca, Christopher J. Conselice
Using a sample of 425 nearby Brightest Cluster Galaxies (BCGs) from von der Linden et al. (2007), we study the relationship between their internal properties (stellar masses, struc…
The Link Between Morphology and Structure of Brightest Cluster Galaxies: Automatic Identification of cDs
Dongyao Zhao, Alfonso Aragón-Salamanca, Christopher J. Conselice
We study a large sample of 625 low-redshift brightest cluster galaxies (BCGs) and link their morphologies to their structural properties. We derive visual morphologies and find tha…
