The most luminous blue quasars at . I. A tale of two X-ray populations
E. Nardini, E. Lusso, G. Risaliti +8
(abridged) We present the X-ray analysis of a sample of 30 luminous quasars at with deep XMM-Newton observations, selected from the SDSS-DR7 to be representative o…
MUSE Analysis of Gas around Galaxies (MAGG) -- I: Survey design and the environment of a near pristine gas cloud at z~3.5
Emma K. Lofthouse, Michele Fumagalli, Matteo Fossati +9
We present the design, methods, and first results of the MUSE Analysis of Gas around Galaxies (MAGG) survey, a large programme on the Multi Unit Spectroscopic Explorer (MUSE) instr…
Quasars as standard candles II: The non linear relation between UV and X-ray emission at high redshifts
Francesco Salvestrini, Guido Risaliti, Susanna Bisogni +2
A tight non-linear relation between the X-ray and the optical-ultraviolet (UV) emission has been observed in Active Galactic Nuclei (AGN) over a wide range of redshift and several…
The MUSE Ultra Deep Field (MUDF). II. Survey design and the gaseous properties of galaxy groups at 0.5 < z < 1.5
M. Fossati, M. Fumagalli, E. K. Lofthouse +12
We present the goals, design, and first results of the MUSE Ultra Deep Field (MUDF) survey, a large programme using the Multi Unit Spectroscopic Explorer (MUSE) instrument at the E…
Fundamental differences in the radio properties of red and blue quasars: evolution strongly favoured over orientation
Lizelke Klindt, David M. Alexander, David J. Rosario +2
A minority of the optically selected quasar population are red at optical wavelengths due to the presence of dust along the line-of-sight. A key focus of many red quasar studies is…
The composite nature of Dust-Obscured Galaxies (DOGs) at z~2-3 in the COSMOS field: II. The AGN fraction
Laurie A. Riguccini, Ezequiel Treister, Karín Menéndez-Delmestre +18
We present the X-ray properties of 108 Dust-Obscured Galaxies (DOGs; F/F 1000) in the COSMOS field, all of which detected in at least three far-infrared bands wit…
Increasing the Discovery Space in Astrophysics - A Collation of Six Submitted White Papers
G. Fabbiano, M. Elvis, A. Accomazzi +46
We write in response to the call from the 2020 Decadal Survey to submit white papers illustrating the most pressing scientific questions in astrophysics for the coming decade. We p…
The MUSE Ultra Deep Field (MUDF). I. Discovery of a group of Ly nebulae associated with a bright quasar pair
E. Lusso, M. Fumagalli, M. Fossati +17
We present first results from Multi Unit Spectroscopic Explorer (MUSE) observations at the Very Large Telescope in the MUSE Ultra Deep Field (MUDF), a arcmi…
Orientation effects on the near-infrared broad band emission of quasars
Susanna Bisogni, Elisabeta Lusso, Alessandro Marconi +1
We recently proposed the equivalent width (EW) of the narrow [OIII]5007Å emission line as an orientation indicator for active galactic nuclei. We tested this method on about $12,30…
Multi-wavelength properties of Type 1 and Type 2 AGN Host Galaxies in the Chandra-COSMOS Legacy Survey
Hyewon Suh, Francesca Civano, Guenther Hasinger +6
We investigate the multi-wavelength properties of host galaxies of 3701 X-ray-selected active galactic nuclei (AGNs) out to z~5 in the Chandra-COSMOS Legacy Survey. Thanks to the e…
