Feedback effect on the observable properties of AGN

Fabio Vito, Fabio Di Mascia, Simona Gallerani +4

Active galactic nuclei (AGN) feedback has a major impact onto the supermassive black-hole (SMBH) growth, the properties of the host galaxies, and their cosmic evolution. We investi…

Enhanced star formation in quasar companions

Tommaso Zana, Simona Gallerani, Stefano Carniani +5

Quasars powered by supermassive black holes (MBH, ) at are predicted to reside in cosmic over-dense regions. However, observations so far could not confi…

Sensitive Chandra coverage of a representative sample of weak-line quasars: revealing the full range of X-ray properties

Q. Ni, W. N. Brandt, B. Luo +8

We present deeper Chandra observations for weak-line quasars (WLQs) in a representative sample that previously had limited X-ray constraints, and perform X-ray photometric analyses…

Lower-Luminosity Obscured AGN Host Galaxies are Not Predominantly in Major-Merging Systems at Cosmic Noon

Erini Lambrides, Marco Chiaberge, Timothy Heckman +15

For over 60 years, the scientific community has studied actively growing central super-massive black holes (active galactic nuclei -- AGN) but fundamental questions on their genesi…

The XMM-SERVS survey: XMM-Newton point-source catalogs for the W-CDF-S and ELAIS-S1 fields

Q. Ni, W. N. Brandt, C. -T. Chen +30

We present the X-ray point-source catalogs in two of the XMM-Spitzer Extragalactic Representative Volume Survey (XMM-SERVS) fields, W-CDF-S (4.6 deg) and ELAIS-S1 (3.2 deg)…

The role of SPICA-like missions and the Origins Space Telescope in the quest for heavily obscured AGN and synergies with Athena

L. Barchiesi, F. Pozzi, C. Vignali +21

In the BH-galaxy co-evolution framework, most of the star-formation (SF) and the black hole (BH) accretion is expected to take place in highly obscured conditions. Thus, obscured A…
