recommendations! Published in 2024 at "Communications in Mathematical Physics"

DOI: 10.1007/s00220-025-05463-7

Abstract: In 1939, Oppenheimer and Snyder showed that the continued gravitational collapse of a self-gravitating matter distribution can result in the formation of a black hole, cf. Oppenheimer and Snyder (Phys Rev 56:455–459, 1939). In this… read more here.

DOI: 10.1088/1475-7516/2020/03/041

Abstract: This article proposes a generalization of the Oppenheimer-Snyder model which describes a bouncing compact object. The corrections responsible for the bounce are parameterized in a general way so as to remain agnostic about the specific… read more here.

DOI: 10.1103/physrevlett.130.101501

Abstract: By considering the quantum Oppenheimer-Snyder model in loop quantum cosmology, a new quantum black hole model whose metric tensor is a suitably deformed Schwarzschild one is derived. The quantum effects imply a lower bound on… read more here.

DOI: 10.3390/universe11080257

Abstract: This work presents a semi-classical, quantum-corrected model of gravitational collapse for a charged, spherically symmetric dust cloud, extending the classical Oppenheimer–Snyder (OS) framework through loop quantum gravity effects. Our goal is to study phenomenological quantum… read more here.
