High-z AGN obscured by host galaxy ISM

Listed in IVOA Registry (Virtual Observatory)

Submillimeter Galaxies (SMGs) at high redshift are among the best targets to investigate the early evolutionary phases in the lifetime of massive systems, during which large gas reservoirs sustain vigorous star formation and efficiently feed the central, buried Super Massive Black Hole (SMBH).

Description

We present the analysis of new ALMA band 4 (1.8-2.4mm) continuum and high-J CO observation of six obscured QSOs (logN_H_>23) hosted by SMGs at z>2.5 in the 7 Ms Chandra Deep Field South (CDF-S).

Sizes and masses of the galaxies are measured to estimate to which extent the host ISM may contribute to the nuclear absorption. We found that at high redshift the galaxy ISM can substantially contribute to the AGN obscuration up to the Compton-thick (10^24^cm^-2^) regime. In addition, we found that all the detected sources show a velocity gradient possibly ascribed to a rotating system, even though two of them could be even associated with a chaotic, possibly merging, structure.
