A physically motivated galaxy size definition across different state-of-the-art hydrodynamical simulations
Elena Arjona-Galvez, Salvador Cardona-Barrero, Robert J. J. Grand +6
Galaxy sizes are a key parameter to distinguishing between different galaxy types and morphologies, reflecting their formation and assembly histories. Several methods define galaxy…
