Abstract: 

The connection between halo gas acquisition through the circumgalactic medium (CGM) and galaxy star formation has long been studied. In a series of two papers, using the IllustrisTNG-100 simulation we put this interplay within the context of the galaxy environment on large scales (several hundreds of kpc), which, to a certain degree, maps out various paths for galaxy interactions. In this talk I will show how the large-scale environment modulates the circumgalactic gas angular momentum, resulting in either enhanced or suppressed star formation inside a galaxy.
