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…

First Detection of Molecular Gas in the Giant Low Surface Brightness Galaxy Malin 1
Gaspar Galaz, Jorge González-López, Viviana Guzmán +17
After over three decades of unsuccessful attempts, we report the first detection of molecular gas emission in Malin 1, the largest spiral galaxy observed to date, and one of the mo…

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…
