Molecular gas hidden in plain sight in the early Universe
Pasquier Noterdaeme, Jens-Kristian Krogager, Sergei Balashev
We report the discovery of an extreme intervening molecular absorber at zabs = 4.1 towards the z = 4.7 quasar SDSS J080023.02+305101.22 revealed through strong H2 absorption that h…
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…
Tracing Cold Gas in Absorption Across Cosmic Time with the SKA
Elizabeth K. Mahony, Neeraj Gupta, Sergei A. Balashev +12
Observing the 21-cm HI line in absorption provides a powerful means of tracing the cold neutral gas in normal and active galaxies across cosmic time. The frequency coverage and sen…
Connecting the dusty dots: dust depletion and extinction of local interstellar clouds
T. Ramburuth-Hurt, A. De Cia, J. -K. Krogager +2
Investigating the chemical complexity of the interstellar medium (ISM) is key for understanding its physical nature and evolution. In this work, we study parsec-scale interstellar…
Chemodynamical properties of gas-rich galaxies: a comparison of observations and simulations
Anna Velichko, Yves Revaz, Annalisa De Cia +4
We perform a comprehensive analysis of the chemical and dynamical properties of quasar-damped Lyman-α (DLA) galaxies and compare these to the GEAR chemodynamical simulations. Speci…
Spectroscopic characterization of a remarkable temporally varying, triple-lensed quasar at z=2.67
Charlie Lind-Thomsen, Kasper E. Heintz, Albert Sneppen +5
Gravitationally lensed quasars are viable cosmic tools for constraining a diversity of fundamental astrophysical phenomena; They enable identification of faint, low-mass supermassi…
