Title: Evolution of Razor-Thin Stellar Discs: Insights from N-body Simulations
Title: Evolution of Razor-Thin Stellar Discs: Insights from N-body Simulations
Abstract: Ultra-thin galaxies (UTGs), characterized by extreme axial ratios (a/b > 20), are among the most striking and poorly understood morphologies in the local universe. These low surface brightness, bulgeless, isolated systems offer a unique window into disc assembly, vertical structure, and the role of dark matter in shaping galaxy evolution. In this talk, using observationally constrained N-body simulations of FGC 2366, the thinnest known galaxy, we systematically try to understand how the shape of the dark matter halo and the stellar mass fraction govern the long-term evolution of razor-thin stellar discs.
