Description

Angular momentum is a fundamental property that shapes the evolution of disc galaxies, strongly influencing the internal mechanisms that regulate star formation. In an ideally closed system, angular momentum would be conserved; however, because galaxies continuously interact with their environments, their angular momentum content is expected to change over time. Despite extensive work, a clear correlation between the angular momentum content of disc galaxies and their environment remains uncertain.

In this talk, we examine how angular momentum varies across both observed and simulated galaxies, using samples drawn from the AMIGA catalogue and the TNG simulations. By probing a range of environments, our analysis offers new insight into the intrinsic impact of environmental processes on the angular momentum content of disc galaxies and discusses the implications of these findings for models of galaxy evolution.
