We use a simplified model where the inhomogeneity is a nested region with a slightly higher density of dust, with a positively curved spatial section. We use this setup to illustrate the concepts of apparent horizon and event horizon of the black hole that forms5 p.application/pdfengcc-by-nc-nd (c) Rodríguez, 2022http://creativecommons.org/licenses/by-nc-nd/3.0/es/Col·lapse gravitacionalForats negres (Astronomia)Treballs de fi de grauGravitational collapseBlack holes (Astronomy)Bachelor's thesesinfo:eu-repo/semantics/bachelorThesisinfo:eu-repo/semantics/openAccess
