Investigating the Star-Formation Characteristics of Radio Active Galactic Nuclei
Bojun Zhang, Fan Zou, W. N. Brandt +5
The coevolution of supermassive black holes and their host galaxies represents a fundamental question in astrophysics. One approach to investigating this question involves comparin…
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…
High-quality Extragalactic Legacy-field Monitoring (HELM) with DECam
Ming-Yang Zhuang, Qian Yang, Yue Shen +45
High-quality Extragalactic Legacy-field Monitoring (HELM) is a long-term observing program that photometrically monitors several well-studied extragalactic legacy fields with the D…
Exploring Changing-look Active Galactic Nuclei with the Sloan Digital Sky Survey V: First Year Results
Grisha Zeltyn, Benny Trakhtenbrot, Michael Eracleous +32
"Changing-look" active galactic nuclei (CL-AGNs) challenge our basic ideas about the physics of accretion flows and circumnuclear gas around supermassive black holes. Using first-y…
The environmental dependence of X-ray AGN activity at
E. Noordeh, R. E. A. Canning, A. King +9
We present an analysis of the X-ray Active Galactic Nucleus (AGN) population in a sample of seven massive galaxy clusters in the redshift range . We utilize high-quali…
Linking black-hole growth with host galaxies: The accretion-stellar mass relation and its cosmic evolution
G. Yang, W. N. Brandt, F. Vito +9
Previous studies suggest that the growth of supermassive black holes (SMBHs) may be fundamentally related to host-galaxy stellar mass (). To investigate this SMBH growth-$…
X-ray spectral analyses of AGNs from the 7Ms Chandra Deep Field-South survey: the distribution, variability, and evolution of AGN's obscuration
Teng Liu, Paolo Tozzi, Jun-Xian Wang +18
We present a detailed spectral analysis of the brightest Active Galactic Nuclei (AGN) identified in the 7Ms Chandra Deep Field South (CDF-S) survey over a time span of 16 years. Us…
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}…
Mid-infrared luminous quasars in the GOODS-Herschel fields: a large population of heavily-obscured, Compton-thick quasars at z~2
A. Del Moro, D. M. Alexander, F. E. Bauer +10
We present the infrared (IR) and X-ray properties of a sample of 33 mid-IR luminous quasars (L(6 micron)>6x10 erg/s) at redshift z~1-3, identified through detailed spectr…
Photometric Redshifts in the Hawaii-Hubble Deep Field-North (H-HDF-N)
G. Yang, Y. Q. Xue, B. Luo +11
We derive photometric redshifts (\zp) for sources in the entire ( deg) Hawaii-Hubble Deep Field-North (\hdfn) field with the EAzY code, based on point spread function-…
The sub-mJy radio population of the E-CDFS: optical and infrared counterpart identification
M. Bonzini, V. Mainieri, P. Padovani +9
We study a sample of 883 sources detected in a deep Very Large Array survey at 1.4 GHz in the Extended Chandra Deep Field South. The paper focuses on the identification of their op…
