Discovery of a galaxy overdensity around a powerful, heavily obscured FRII radio galaxy at z=1.7: star formation promoted by large-scale AGN feedback?
R. Gilli, M. Mignoli, A. Peca +25
We report the discovery of a galaxy overdensity around a Compton-thick Fanaroff-Riley type II (FRII) radio galaxy at z=1.7 in the deep multiband survey around the z=6.3 QSO SDSS J1…
Does black-hole growth depend fundamentally on host-galaxy compactness?
Q. Ni, G. Yang, W. N. Brandt +5
Possible connections between central black-hole (BH) growth and host-galaxy compactness have been found observationally, which may provide insight into BH-galaxy coevolution: compa…
The X-ray properties of quasars: no evident evolution of accretion physics in the first Gyr of the Universe
Fabio Vito, William Nielsen Brandt, Franz Erik Bauer +10
X-ray emission from QSOs has been used to assess SMBH accretion properties up to ~6. However, at only ~15 QSOs are covered by sensitive X-ray observations, preventing a st…
Discovery of the first heavily obscured QSO candidate at in a close galaxy pair
Fabio Vito, William Nielsen Brandt, Franz Erik Bauer +14
While theoretical arguments predict that most of the early growth of supermassive black holes (SMBHs) happened during heavily obscured phases of accretion, current methods used for…
A magnetar-powered X-ray transient as the aftermath of a binary neutron-star merger
Y. Q. Xue, X. C. Zheng, Y. Li +14
Neutron star-neutron star mergers are known to be associated with short gamma-ray bursts. If the neutron star equation of state is sufficiently stiff, at least some of such mergers…
Piercing Through Highly Obscured and Compton-thick AGNs in the Chandra Deep Fields: I. X-ray Spectral and Long-term Variability Analyses
Junyao Li, Yongquan Xue, Mouyuan Sun +13
We present a detailed X-ray spectral analysis of 1152 AGNs selected in the Chandra Deep Fields (CDFs), in order to identify highly obscured AGNs (…
Cosmic evolution of supermassive black holes: A view into the next two decades
Francesca Civano, Nico Cappelluti, Ryan Hickox +38
The discoveries made over the past 20 years by Chandra and XMM-Newton surveys in conjunction with multiwavelength imaging and spectroscopic data available in the same fields have s…
Electromagnetic Window into the Dawn of Black Holes
Zoltán Haiman, William N. Brandt, Alexey Vikhlinin +28
Massive 10^6-10^10 Msun black holes (BHs) are ubiquitous in local galactic nuclei. They were common by the time the Universe is several Gyr old, and many of them were in place with…
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…
The X-ray emission of z>2.5 active galactic nuclei can be obscured by their host galaxies
C. Circosta, C. Vignali, R. Gilli +6
We present a multi-wavelength study of seven AGN at spectroscopic redshift >2.5 in the 7 Ms Chandra Deep Field South, selected to have good FIR/sub-mm detections. Our aim is to inv…
