Transitions in Simulated Low-Mass Galaxies</span></b> </div>
<div align="center"><br>
Disc formation in low-mass galaxies is a key topic in
understanding galactic evolution and the small-scale structure
of the Universe. Unlike their more massive counterparts,
low-mass galaxies (M_star < 10^10 M_sun) exhibit significant
morphological diversity, with many displaying dynamics dominated
by velocity dispersion rather than rotation. In this study,
using data from the FIREbox and FIRE zoom-in cosmological
simulations, we investigate the physical conditions that govern
disc formation in such systems, focusing on the interplay
between stellar feedback and internal gas dynamics. We find that
disc formation in low-mass galaxies can occur under specific
conditions, such as sufficiently high halo spin, the presence of
cold gas with high angular momentum capable of forming
rotationally supported young stars, and even interactions with
satellites that induce disc-like structures. Furthermore, we
identify a morphological transition from spheroidal to disky
systems at M_star ~ 10^9 M_sun. These findings offer new
insights into the mechanisms that drive structure formation in
low-mass galaxies, with important implications for galaxy
formation models and our understanding of galactic evolution. <br>
