On the Dusty Proximate Damped Lyman-α System toward Q2310-3358 at z = 2.40
S. Han, J. -K. Krogager, C. Ledoux +6
Quasar absorption systems not only affect the way quasars are selected, but also serve as key probes of galaxies, providing insight into their chemical evolution and interstellar m…
A large, chemically enriched, neutral gas reservoir in a galaxy at z = 6.782
A. Saccardi, S. D. Vergani, L. Izzo +23
The chemical characterization of galaxies in the first billion years after the Big Bang is one of the central goals of current astrophysics. Optical/near-infrared spectroscopy of l…
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…
Comparing emission- and absorption-based gas-phase metallicities in GRB host galaxies at using JWST
P. Schady, R. M. Yates, L. Christensen +34
Much of what is known of the chemical composition of the universe is based on emission line spectra from star forming galaxies. Emission-based inferences are, nevertheless, model-d…
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…
Reconstructing the extended structure of multiple sources strongly lensed by the ultra-massive elliptical galaxy SDSS J0100+1818
A. Bolamperti, C. Grillo, R. Cañameras +2
We study the total and baryonic mass distributions of the deflector SDSS J0100+1818 through a full strong lensing analysis. The system is composed by an ultra-massive early-type ga…
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…
Constraining the multi-scale dark-matter distribution in CASSOWARY 31 with strong gravitational lensing and stellar dynamics
H. Wang, R. Cañameras, G. B. Caminha +6
We study the inner structure of the group-scale lens CASSOWARY 31 (CSWA 31) by adopting both strong lensing and dynamical modeling. CSWA 31 is a peculiar lens system. The brightest…
Steep extinction towards GRB 140506A reconciled from host galaxy observations: Evidence that steep reddening laws are local
K. E. Heintz, J. P. U. Fynbo, P. Jakobsson +14
We present the spectroscopic and photometric late-time follow-up of the host galaxy of the long-duration Swift gamma-ray burst GRB 140506A at z = 0.889. The optical and near-infrar…
