Chandra Lensing-cluster Ultradeep Extragalactic Survey (CLUES) I: A 2 Ms Point-Source Catalog of the Abell 2744 Field

Shouyi Wang, Fan Zou, Elena Gallo +10

In the first paper of the Chandra Lensing-cluster Ultradeep Extragalactic Survey (CLUES), we present an ultradeep 2 Ms X-ray survey of the Abell 2744 field constructed from 101 arc…

Systematic Monitoring of Extreme X-ray Variability from Weak-line Quasars

Madison Reich, W. N. Brandt, Bin Luo +5

We present the results of a multi-cycle Chandra program to systematically monitor the X-ray variability of 10 weak-line quasars (WLQs) that previously had limited multi-epoch X-ray…

Departures from Standard Disk Predictions in Intensive Ground-Based Monitoring of Three AGN

Diego Gonzalez-Buitrago, Aaron J. Barth, Rick Edelson +42

We present ground-based, multi-band light curves of the AGN Mrk~509, NGC\,4151, and NGC\,4593 obtained contemporaneously with \sw\, monitoring. We measure cross-correlation lags re…

A Rapidly Accreting Active Galactic Nucleus Hidden in a Dust-Obscured Galaxy at

Nathan Cristello, Fan Zou, William N. Brandt +3

Dust-obscured galaxies (DOGs) containing central supermassive black holes (SMBHs) that are rapidly accreting (i.e., having high Eddington ratios, ) may represent a…

The X-ray enhancements of radio-loud quasars at high redshift: New results at

Zihao Zuo, Shifu Zhu, W. N. Brandt +4

Highly radio-loud quasars (HRLQs; ) at show apparent enhanced X-ray emission compared to matched HRLQs at lower redshifts, perhaps due to a redshift-depend…

Evident black hole-bulge coevolution in the distant universe

Guang Yang, W. N. Brandt, D. M. Alexander +4

Observations in the local universe show a tight correlation between the masses of supermassive black holes (SMBHs; ) and host-galaxy bulges (), suggestin…

A New, Faint Population of X-ray Transients

F. E. Bauer, E. Treister, K. Schawinski +22

We report on the detection of a remarkable new fast high-energy transient found in the Chandra Deep Field-South, robustly associated with a faint ( mag, $z_{\rm ph}…

X-ray, Optical, and Infrared Imaging and Spectral Properties of the 1 Ms Chandra Deep Field North Sources

A. J. Barger, L. L. Cowie, W. N. Brandt +5

We present the optical, near-infrared, submillimeter, and radio follow-up catalog of the X-ray selected sources from the 1 Ms Chandra observation of the Hubble Deep Field North reg…

The Chandra Deep Field-North Survey and the Cosmic X-ray Background

W. N. Brandt, D. M. Alexander, F. E. Bauer +1

Chandra has performed a 1.4 Ms survey centred on the Hubble Deep Field-North (HDF-N), probing the X-ray Universe 55-550 times deeper than was possible with pre-Chandra missions. We…

Detection of Nuclear X-ray Sources in Nearby Galaxies with Chandra

Luis C. Ho, Eric D. Feigelson, Leisa K. Townsley +7

We report preliminary results from an arcsecond-resolution X-ray survey of nearby galaxies using ACIS on board Chandra. The total sample consists of 41 low-luminosity AGNs, includi…
