Deepest view of AGN X-ray variability with the 7 Ms Chandra Deep Field-South survey
X. C. Zheng, Y. Q. Xue, W. N. Brandt +13
We systematically analyze X-ray variability of active galactic nuclei (AGNs) in the 7~Ms \textit{Chandra} Deep Field-South survey. On the longest timescale ( years), we…
The NuSTAR Extragalactic Survey: Average broad-band X-ray spectral properties of the NuSTAR detected AGN
A. Del Moro, D. M. Alexander, J. A. Aird +18
We present a study of the average X-ray spectral properties of the sources detected by the NuSTAR extragalactic survey, comprising observations of the E-CDFS, EGS and COSMOS fields…
High-redshift AGN in the Chandra Deep Fields: the obscured fraction and space density of the sub- population
F. Vito, W. N. Brandt, G. Yang +14
We investigate the population of high-redshift () AGN selected in the two deepest X-ray surveys, the 7 Ms \textit{Chandra} Deep Field-South and 2 Ms \textit{Chandra} D…
Tracing the accretion history of supermassive Black Holes through X-ray variability: results from the Chandra Deep Field-South
M. Paolillo, I. Papadakis, W. N. Brandt +15
We study the X-ray variability properties of distant AGNs in the Chandra Deep Field-South region over 17 years, up to , and compare them with those predicted by models bas…
Black-Hole Growth is Mainly Linked to Host-Galaxy Stellar Mass rather than Star Formation Rate
G. Yang, C. -T. J. Chen, F. Vito +14
We investigate the dependence of black-hole accretion rate (BHAR) on host-galaxy star formation rate (SFR) and stellar mass () in the CANDELS/GOODS-South field in the redshift…
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…
