The WISSH quasars project XI. The mean Spectral Energy Distribution and Bolometric Corrections of the most luminous quasars
Ivano Saccheo, Angela Bongiorno, Enrico Piconcelli +18
Hyper-luminous Quasi-Stellar Objects (QSOs) represent the ideal laboratory to investigate Active Galactic Nuclei (AGN) feedback mechanism since their formidable energy release caus…
Mass assembly and AGN activity at in the dense environment of XDCPJ0044.0-2033
M. Lepore, A. Bongiorno, P. Tozzi +4
XDCP0044.0-2033 is the most massive galaxy cluster known at z>1.5 and its core shows a high density of galaxies which are experiencing mergers and hosting nuclear activity. We pres…
Dusty winds clear JWST super-early galaxies
Fabrizio Fiore, Andrea Ferrara, Manuela Bischetti +2
The JWST discovery of a number of super-early (redshift ), blue galaxies requires these systems to be essentially dust-free in spite of their large stellar masses. A possible…
Detection of companion galaxies around hot dust-obscured hyper-luminous galaxy W0410-0913
M. Ginolfi, E. Piconcelli, L. Zappacosta +18
The phase transition between galaxies and quasars is often identified with the rare population of hyper-luminous, hot dust-obscured galaxies. Galaxy formation models predict these…
The WISSH quasars project X. Discovery of a multi-component and highly-variable UV ultra-fast outflow in a z=3.6 quasar
G. Vietri, T. Misawa, E. Piconcelli +16
We report on the variability of a multi-component broad absorption line (BAL) system observed in the hyper-luminous quasar J1538+0855 at z=3.6. Observations from SDSS, VLT, LBT and…
