The WISSH QSOs project IX. Cold gas content and environment of luminous QSOs at z~2.4-4.7

M. Bischetti, C. Feruglio, E. Piconcelli +23

Sources at the brightest end of QSO luminosity function during the peak epoch of star formation and black hole accretion (z~2-4, i.e. Cosmic noon) are privileged sites to study the…

The WISSH quasars project V. ALMA reveals the assembly of a giant galaxy around a z=4.4 hyper-luminous QSO

M. Bischetti, E. Piconcelli, C. Feruglio +11

We present an ALMA high-resolution observation of the 840 um continuum and [CII] line emission in the WISE-SDSS selected hyper-luminous (WISSH) QSO J1015+0020 at z~4.4. Our analysi…

Multiple AGN activity during the BCG assembly of XDCPJ0044.0-2033 at z~1.6

A. Travascio, A. Bongiorno, P. Tozzi +13

Undisturbed galaxy clusters are characterized by a massive and large elliptical galaxy at their center, i.e. the Brightest Cluster Galaxy (BCG). How these central galaxies form is…

The WISSH Quasars Project I. Powerful ionised outflows in hyper-luminous quasars

M. Bischetti, E. Piconcelli, G. Vietri +19

Models and observations suggest that both power and effects of AGN feedback should be maximised in hyper-luminous (L_Bol>10^47 erg/s) quasars, i.e. objects at the brightest end of…

The WISSH quasars project VII. The impact of extreme radiative field in the accretion disk and X-ray corona interplay

L. Zappacosta, E. Piconcelli, M. Giustini +14

Hyperluminous quasars ( erg s) are ideal laboratories to study the interaction and impact of extreme radiative field and the most powerful winds…

Molecular outflow and feedback in the obscured Quasar XID2028 revealed by ALMA

M. Brusa, G. Cresci, E. Daddi +29

We imaged with ALMA and ARGOS/LUCI the molecular gas and the dust and stellar continuum in XID2028, an obscured QSO at z=1.593, where the presence of a massive outflow in the ioniz…
