Kinematic Analysis of an Ultrastrong Mg II Absorber at z ≈ 1.13 Linked to Circumgalactic Gas Structures

We present a spectroscopic and imaging analysis of the z _gal  ≈ 1.1334 ultrastrong Mg ii absorption system identified in the Very Large Telescope/UVES spectrum of a background quasar located at ρ  ≈ 18 kpc from a star-forming galaxy. Low-ionization metal lines like Mg i , Fe ii , and Ca ii are also...
