Does the lockstep growth between black holes and bulges create their mass relation?
Guang Yang, W. N. Brandt, David M. Alexander +7
Recent studies have revealed a strong relation between sample-averaged black-hole (BH) accretion rate (BHAR) and star formation rate (SFR) among bulge-dominated galaxies, i.e., "lo…
Comparison of star formation histories of AGN and non-AGN galaxies
G. Mountrichas, V. Buat, G. Yang +6
We use AGN with , from the COSMOS-Legacy survey that lie within the UltraVISTA region and cross match them with the LEGA-C catalogue. The…
The Nature of Luminous Quasars with Very Large C IV Equivalent Widths
Shuqi Fu, W. N. Brandt, Fan Zou +5
We report results for a complete sample of ten luminous radio-quiet quasars with large C IV equivalent widths (EW > 150 A). For 8/10 we performed Chandra snapshot observations. We…
Spectral Energy Distributions in Three Deep-Drilling Fields of the Vera C. Rubin Observatory Legacy Survey of Space and Time: Source Classification and Galaxy Properties
Fan Zou, W. N. Brandt, Chien-Ting Chen +9
W-CDF-S, ELAIS-S1, and XMM-LSS will be three Deep-Drilling Fields (DDFs) of the Vera C. Rubin Observatory Legacy Survey of Space and Time (LSST), but their extensive multi-waveleng…
A quasar shedding its dust cocoon at redshift 2
Weimin Yi, W. N. Brandt, Q. Ni +12
We present the first near-IR spectroscopy and joint analyses of multi-wavelength observations for SDSS J082747.14+425241.1, a dust-reddened, weak broad emission-line quasar (WLQ) u…
Connecting Low- and High-Redshift Weak Emission-Line Quasars via HST Spectroscopy of Ly Emission
Jeremiah D. Paul, Richard M. Plotkin, Ohad Shemmer +10
We present ultraviolet spectroscopy covering the Ly + N V complex of six candidate low-redshift () weak emission-line quasars (WLQs) based on observations with th…
Sensitive Chandra coverage of a representative sample of weak-line quasars: revealing the full range of X-ray properties
Q. Ni, W. N. Brandt, B. Luo +8
We present deeper Chandra observations for weak-line quasars (WLQs) in a representative sample that previously had limited X-ray constraints, and perform X-ray photometric analyses…
