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…
A massive, neutral gas reservoir permeating a galaxy proto-cluster after the reionization era
Kasper E. Heintz, Jake S. Bennett, Pascal A. Oesch +21
Galaxy clusters are the most massive, gravitationally-bound structures in the Universe, emerging through hierarchical structure formation of large-scale dark matter and baryon over…
Uncovering the physical origin of the prominent Lyman- emission and absorption in GS9422 at
Chamilla Terp, Kasper E. Heintz, Darach Watson +5
We present a comprehensive spectro-photometric analysis of the galaxy GS9422 from the JADES GTO survey located at , anomalously showing a simultaneous strong Ly emissio…
Absence of radio-bright dominance in a near-infrared selected sample of red quasars
S. Vejlgaard, J. P. U. Fynbo, K. E. Heintz +5
(Abridged). We explore the fraction of radio loud quasars in the eHAQ+GAIA23 sample, which contains quasars from the High A(V) Quasar (HAQ) Survey, the Extended High A(V) Quasar (e…
The galaxy counterpart and environment of the dusty Damped Lyman-alpha Absorber at z=2.226 towards Q1218+0832
J. P. U. Fynbo, L. B. Christensen, S. J. Geier +8
We report on further observations of the field of the quasar Q1218+0832. Geier et al. 2019 presented the discovery of the quasar resulting from a search for quasars reddened and di…
The cosmic build-up of dust and metals. Accurate abundances from GRB-selected star-forming galaxies at
K. E. Heintz, A. De Cia, C. C. Thöne +38
The chemical enrichment of dust and metals in the interstellar medium (ISM) of galaxies throughout cosmic time is one of the key driving processes of galaxy evolution. Here we stud…
Extreme damped Lyman- absorption in young star-forming galaxies at
Kasper E. Heintz, Darach Watson, Gabriel Brammer +18
The onset of galaxy formation is thought to be initiated by the infall of neutral, pristine gas onto the first protogalactic halos. However, direct constraints on the abundance of…
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…
