A tidal disruption event in a quasar at redshift 7.19

S. Fujimoto, Q. Fei, G. B. Brammer +41

We report a long-lived nuclear transient in GNz7q, a red quasar at powered by a black hole and hosted by a compact, dusty starburst galaxy. Th…

Extreme outflow velocities and weak UV emission lines indicate quasars shedding their dust cocoons

Guozhen Ma, Stefan J. Geier, Johan P. U. Fynbo +11

The recently discovered low-ionisation broad absorption line (LoBAL) quasar GQ 13092904 is unusual due to its very broad, highly blueshifted absorption troughs and an absence of…

JWST spectroscopy of galaxies at : Damped Ly absorbers reveal efficient star formation and hidden redshift biases

Kasper E. Heintz, Clara L. Pollock, Joris Witstok +23

Recent observations with JWST have revealed a remarkable population of surprisingly luminous galaxies at redshifts . Their abundance exceed predictions from simulations and e…

Dilution of chemical enrichment in galaxies 600 Myr after the Big Bang

Kasper E. Heintz, Gabriel B. Brammer, Clara Giménez-Arteaga +10

Galaxies throughout the last 12 Gyr of cosmic time follow a single, universal relation that connects their star-formation rates (SFRs), stellar masses () and chemical abun…

Dissecting the interstellar medium of a z=6.3 galaxy: X-shooter spectroscopy and HST imaging of the afterglow and environment of the Swift GRB 210905A

A. Saccardi, S. D. Vergani, A. De Cia +35

The study of the properties of galaxies in the first billion years after the Big Bang is one of the major topic of current astrophysics. Optical/near-infrared spectroscopy of the a…

The VANDELS survey: the ionizing properties of star-forming galaxies at using deep rest-frame ultraviolet spectroscopy

A. Saldana-Lopez, D. Schaerer, J. Chisholm +13

To better understand the ionizing properties of galaxies in the EoR, we investigate deep, rest-frame ultraviolet (UV) spectra of star-forming galaxies at $3 \leq z \le…
