Euclid. I. Overview of the Euclid mission

Euclid Collaboration, Y. Mellier, Abdurro'uf +1134

The current standard model of cosmology successfully describes a variety of measurements, but the nature of its main ingredients, dark matter and dark energy, remains unknown. Eucl…

The discovery of a highly accreting, radio-loud quasar at z=6.82

Eduardo Banados, Chiara Mazzucchelli, Emmanuel Momjian +17

Radio sources at the highest redshifts can provide unique information on the first massive galaxies and black holes, the densest primordial environments, and the epoch of reionizat…

Quantitative Constraints on the Reionization History from the IGM Damping Wing Signature in Two Quasars at z > 7

Frederick B. Davies, Joseph F. Hennawi, Eduardo Bañados +10

During reionization, neutral hydrogen in the intergalactic medium (IGM) imprints a damping wing absorption feature on the spectrum of high-redshift quasars. A detection of this sig…

Mg II Absorption at 2<z<7 with Magellan/FIRE, III. Full Statistics of Absorption Towards 100 High-Redshift QSOs

Shi-Fan S. Chen, Robert A. Simcoe, Paul Torrey +12

We present final statistics from a survey for intervening MgII absorption towards 100 quasars with emission redshifts between and . Using infrared spectra from Mag…

The extent of the MgII absorbing circum-galactic medium of quasars

E. P. Farina, R. Falomo, R. Scarpa +3

We investigate the extent and the properties of the MgII cool, low-density absorbing gas located in the halo and in the circum-galactic environment of quasars, using a sample of 31…

A Molecular Line Scan in the Hubble Deep Field North: Constraints on the CO Luminosity Function and the Cosmic H2 Density

F. Walter, R. Decarli, M. Sargent +19

We present direct constraints on the CO luminosity function at high redshift and the resulting cosmic evolution of the molecular gas density, (z), based on a blind mole…
