We study the formation of 53 galaxy cluster-size dark matter halos (M = 1014.0-14.76 M sun) formed within a pair of cosmological Λ cold dark matter N-body...
The Assembly of Supermassive Black Holes at z < 1 in Early-type Galaxies from Scaling Relations
The assembly of supermassive black hole (SMBH) mass (M •) and stellar mass (M *) in galaxies can be studied via the redshift evolution of the M •–M * relation...
The Average Size and Temperature Profile of Quasar Accretion Disks
We use multi-wavelength microlensing measurements of a sample of 10 image pairs from 8 lensed quasars to study the structure of their accretion disks. By using...
We present surface photometry and stellar kinematics of NGC 4431, a barred dwarf galaxy in the Virgo Cluster undergoing a tidal interaction with one of its...
The Bias from Hydrodynamic Simulations: Mapping Baryon Physics onto Dark Matter Fields
This paper investigates the hierarchy of baryon physics assembly bias relations obtained from state-of-the-art hydrodynamic simulations with respect to the...
The Binary Mass Ratio in the Black Hole Transient MAXI J1820+070
We present intermediate-resolution spectroscopy of the optical counterpart to the black hole X-ray transient MAXI J1820+070 (=ASASSN-18ey) obtained with the...
The Black Hole Mass-Color Relations for Early- and Late-type Galaxies: Red and Blue Sequences
The tight correlations between supermassive black hole (SMBH) mass (M BH) and the properties of the host galaxy have useful implications for our understanding...
The Böhm-Vitense Gap: The Role of Turbulent Convection
``Böhm-Vitense gaps,'' discontinuities in the color distribution of A-F type stars along the main sequence, have traditionally been attributed to the abrupt...
The BOSS Emission-line Lens Survey. III. Strong Lensing of Lyα Emitters by Individual Galaxies
We introduce the Baryon Oscillation Spectroscopic Survey (BOSS) Emission-Line Lens Survey GALaxy-Lyα EmitteR sYstems (BELLS GALLERY) Survey, which is a Hubble...
