The XQR-30 Metal Absorber Catalog: 778 Absorption Systems Spanning 2 < z < 6.5
Rebecca L. Davies, Emma Ryan-Weber, Valentina D'Odorico +11
Intervening metal absorption lines in the spectra of z > 6 quasars are fundamental probes of the ionization state and chemical composition of circumgalactic and intergalactic gas n…
Widespread, strong outflows in XQR-30 quasars at the Reionisation epoch
M. Bischetti, C. Feruglio, V. D'Odorico +23
Luminous quasars powered by accretion onto billion solar mass black holes already exist at the epoch of Reionisation, when the Universe was 0.5-1 Gyr old. These objects likely resi…
The [CII] and FIR properties of z>6 radio-loud quasars
Yana Khusanova, Eduardo Bañados, Chiara Mazzucchelli +9
There are only five radio-loud quasars currently known within 1 Gyr from the Big Bang () and the properties of their host galaxies have not been explored in detail. We present…
AGN-driven outflows and the formation of Ly nebulae around high-z quasars
Tiago Costa, Fabrizio Arrigoni Battaia, Emanuele P. Farina +3
The detection of Ly nebulae around quasars provides evidence for extended gas reservoirs around the first rapidly growing supermassive black holes. Observations of…
Molecular gas in z~6 quasar host galaxies
Roberto Decarli, Antonio Pensabene, Bram Venemans +19
We investigate the molecular gas content of z~6 quasar host galaxies using the IRAM / Northern Extended Millimeter Array. We target the 3mm dust continuum, and the line emission fr…
Constraining galaxy overdensities around three z~6.5 quasars with ALMA and MUSE
Romain A. Meyer, Roberto Decarli, Fabian Walter +6
We quantify galaxy overdensities around three high-redshift quasars with known [CII] 158um companions: PJ231-20 (z=6.59), PJ308-21 (z=6.24) and J0305-3150 (z=6.61). Recent SCUBA2 i…
