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…
AGN in overdense environments at high- with AXIS
Fabio Vito, Paolo Tozzi, Roberto Gilli +3
Overdense regions at high redshift () are perfect laboratories to study the relations between environment and SMBH growth, and the AGN feedback processes on the surrou…
Are there more galaxies than we see around high- quasars?
Tommaso Zana, Stefano Carniani, David Prelogović +5
Whether or not quasars lie in the most massive dark-matter halos of the Universe is still a subject of dispute. While most theoretical studies support this scenario,…
Probing massive black holes with gravitational waves
Srija Chakraborty, Simona Gallerani, Tommaso Zana +6
We investigate the coalescence of massive black hole () binaries (MBHBs) at by adopting a suite of cosmological hydrodynamical simu…
LBT-MODS spectroscopy of high-redshift candidates in the Chandra J1030 field. A newly discovered z2.8 large scale structure
Stefano Marchesi, Marco Mignoli, Roberto Gilli +13
We present the results of a spectroscopic campaign with the Multi-Object Double Spectrograph (MODS) instrument mounted on the Large Binocular Telescope (LBT), aimed at obtaining a…
X-ray Unveiling Events in a z~1.6 Active Galactic Nucleus in the 7 Ms Chandra Deep Field-South
Li-Ming Yu, Bin Luo, William N. Brandt +14
We investigate the extreme X-ray variability of a z = 1.608 active galactic nucleus in the 7 Ms Chandra Deep Field-South (XID 403), which showed two significant X-ray brightening e…
