Singular and non-singular endstates in massless scalar field collapse (1107.4112v1)
Published 20 Jul 2011 in gr-qc and astro-ph.HE
Abstract: We study the collapse of a massless scalar field coupled to gravity. A class of blackhole solutions are identified. We also report on a class of solutions where collapse starts from a regular spacelike surface but then the collapsing scalar field freezes. As a result, in these solutions, a black hole does not form, neither is there any singularity in the future.
