Gravitational Waves from Gravitational Collapse [PDF]
Living Reviews in Relativity, 2011 Gravitational-wave emission from stellar collapse has been studied for nearly four decades. Current state-of-the-art numerical investigations of collapse include those that use progenitors with more realistic angular momentum profiles, properly treat ...

Critical Phenomena in Gravitational Collapse [PDF]
Living Reviews in Relativity, 2007 As first discovered by Choptuik, the black hole threshold in the space of initial data for general relativity shows both surprising structure and surprising simplicity.

On the quantum corrected gravitational collapse
Physics Letters B, 2015 Based on a previously found general class of quantum improved exact solutions composed of non-interacting (dust) particles, we model the gravitational collapse of stars.

Gravitational Waves from Gravitational Collapse
Living Reviews in Relativity, 2003 Gravitational wave emission from the gravitational collapse of massive stars has been studied for more than three decades. Current state-of-the-art numerical investigations of collapse include those that use progenitors with more realistic angular ...

Gravitational quantum collapse in dilute systems
Comptes Rendus. Physique, 2022 Penrose has suggested that large fluctuations of the gravitational energy of quantum systems, resulting from fluctuations of its density in space, may induce a quantum collapse mechanism [1], but he did not propose a precise dynamics for this process. We

Gravitational collapse in Rastall gravity
Physics Letters B, 2019 We study spherically symmetric gravitational collapse of a homogeneous perfect fluid in Rastall gravity. Considering a linear equation of state (EoS) for the fluid profiles, we examine the conditions under which the collapse scenario could end in a ...

The nature of the naked singularity in generalized Vaidya spacetime and white hole geodesics
Physics of Complex Systems, 2021 This paper gives conditions to the energy-momentum tensor when the gravitational collapse of generalized Vaidya spacetime results in a naked singularity.

Gravitational Wave Speed: Undefined. Experiments Proposed [PDF]
Research Ideas and Outcomes, 2018 Since changes in all 4 dimensions of spacetime are components of displacement for gravitational waves, a theoretical result is presented that their speed is undefined, and that the Theory of Relativity is not reliable to predict their speed ...

Gravitational collapse of quantum fields and Choptuik scaling
Journal of High Energy Physics, 2022 Gravitational collapse into a black hole has been extensively studied with classical sources. We develop a new formalism to simulate quantum fields forming a black hole.

On the Induced Gravitational Collapse
EPJ Web of Conferences, 2018 The induced gravitational collapse (IGC) paradigm has been applied to explain the long gamma ray burst (GRB) associated with type Ic supernova, and recently the Xray flashes (XRFs).
