The Synthetic Absorption Line Spectral Almanac (SALSA)
Dylan Nelson, Celine Peroux, Philipp Richter +10
We create the first large-scale mock spectroscopic survey of gas absorption sightlines traversing the interstellar medium (ISM), circumgalactic medium (CGM), and intergalactic medi…
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. Spec…
MUSE-ALMA Haloes XIII. Molecular gas in HI-selected galaxies
Victoria Bollo, Celine Peroux, Martin Zwaan +11
We present new results from the MUSE-ALMA Haloes survey, covering 79 galaxies associated with strong HI absorption at redshift about 0.5. Our ALMA Cycle 10 observations add 39 syst…
Disturbed cold gas in galaxy and structure formation
Siwei Zou, Robert A. Simcoe, Patrick Petitjean +18
Cold and cool gas (T K) in the circumgalactic medium (CGM) and its interaction with galaxies remain poorly understood. Simulations predict that cold gas flows into gala…
The Diversity of Metal-Enrichment and Abundance Patterns at High Redshift: A Magellan Survey of Gas-rich Galaxies Traced by Damped Lyman-alpha Absorbers at z~5
Jianghao Huyan, Varsha P. Kulkarni, Suraj Poudel +3
A powerful technique to trace the signatures of the first stars is through the metal enrichment in concentrated reservoirs of hydrogen, such as the damped Lyman-alpha absorbers (DL…
Prospects for studying million-degree gas in the Milky Way halo using the forbidden optical [FeX] and [FeXIV] intersystem lines
P. Richter, F. Ruenger, N. Lehner +5
The Milky Way is surrounded by large amounts of hot gas at temperatures T>10^6 K, which represents a major baryon reservoir. We here explore the prospects of studying the hot coron…
