Unveiling large-scale rotational motions in the intragroup medium at z~1 through gravitational-arc tomography

Cédric Ledoux, Fernanda Muñoz-Olivares, L. Felipe Barrientos +8

We present the first spatially resolved characterisation of the cool intragroup medium (IGrM) in a spectroscopically confirmed galaxy group at z=1.167. Using 30 independent sightli…

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…

Mapping the spatial extent of HI-rich absorbers using MgII absorption along gravitational arcs

Trystyn A. M. Berg, Andrea Afruni, Cédric Ledoux +6

HI-rich absorbers seen within quasar spectra contain the bulk of neutral gas in the Universe. However, the spatial extent of these reservoirs are not extensively studied due to the…

Investigating chemical variations between interstellar gas clouds in the Solar neighbourhood

T. Ramburuth-Hurt, A. De Cia, J. -K. Krogager +6

The interstellar medium (ISM) is a fundamental component of the Milky Way. Studying its chemical composition and the level of its chemical diversity gives us insight into the evolu…

DUNE: Dust depletion UNified method across cosmic time and Environments

Christina Konstantopoulou, Annalisa De Cia, Jens-Kristian Krogager +5

We present a novel method to characterize dust depletion, namely, the depletion of metals into dust grains. We used observed correlations among relative abundances combining a tota…
