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…

Spatially Resolved Circumgalactic Medium around a Star-Forming Galaxy Driving a Galactic Outflow at

Ahmed Shaban, Rongmon Bordoloi, John M. O'Meara +6

We report the small-scale spatial variation in cool () Mg II absorption detected in the circumgalactic medium (CGM) of a star-forming galaxy at . The CG…

Modelling of long gamma-ray burst host galaxies at cosmic noon from damped Lyman-α absorption statistics

J. -K. Krogager, A. De Cia, K. E. Heintz +11

We study the properties of long gamma-ray burst (GRB) host galaxies using a statistical modelling framework derived to model damped Lyman- absorbers (DLAs) in quasar spectra at…

Transverse clues on the kpc-scale structure of the circumgalactic medium as traced by C IV absorption

S. Lopez, A. Afruni, D. Zamora +13

We present VLT/MUSE integral-field spectroscopy () of four giant gravitational arcs exhibiting strong C IV absorption at 8 intervening redshifts, $z_{abs}\approx 2…

A New Precise Determination of the Primordial Abundance of Deuterium: Measurement in the metal-poor sub-DLA system at z=3.42 towards quasar J1332+0052

P. A. Kislitsyn, S. A. Balashev, M. T. Murphy +3

The theory of Big Bang nucleosynthesis, coupled with an estimate of the primordial deuterium abundance (D/H)_pr, offers insights into the baryon density of the Universe. Independen…

α-element enhancements in the Magellanic Interstellar Medium: evidence for recent star formation

Annalisa De Cia, Julia Roman-Duval, Christina Konstantopoulou +8

Important questions on the chemical composition of the neutral ISM in the Large Magellanic Cloud (LMC) and Small Magellanic Cloud (SMC) are still open. It is usually assumed that t…
