Quantizing Gravitational Collapse [PDF]
Quantum Theory and Symmetries, 2004 I summarize some results obtained from a canonical quantization of gravitational collapse. The quantization is carried out in Kuchar variables on the LeMaitre-Tolman-Bondi family of spacetimes.

Nature, 1964 With the exception of a few supernova remnants which are in our galaxy, most cosmic radio sources are “radio galaxies”. Although flare stars do emit radio waves occasionally, no ordinary stars with strong, steady radio emission have been found. The typical optical power of stars is from 1030 ergs/sec (white dwarfs) to 1038 ergs/sec (super giants).

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 ...

Gravitinos from Gravitational Collapse [PDF]
Physical Review D, 1997 We reanalyse the limits on the gravitino mass $m_{3/2}$ in superlight gravitino scenarios derived from arguments on energy-loss during gravitational collapse.

Energy Estimates and Gravitational Collapse [PDF]
Communications in Mathematical Physics, 2011 We study the cancelations in the energy estimates for Einstein vacuum equations in order to prove the formation of black holes along evolutions. The novelty of the paper is that, we completely avoid using rotation vector fields to establish the global ...

SPHERICALLY SYMMETRIC GRAVITATIONAL COLLAPSE [PDF]
Modern Physics Letters A, 2009 In this paper, we discuss gravitational collapse of spherically symmetric spacetimes. We derive a general formalism by taking two arbitrary spherically symmetric spacetimes with g00 = 1. Israel's junction conditions are used to develop this formalism. The formulas for extrinsic curvature tensor are obtained.

PLANE SYMMETRIC GRAVITATIONAL COLLAPSE [PDF]
International Journal of Modern Physics A, 2008 In this paper, we derive the general formulation by considering two arbitrary plane symmetric space–times using Israel's method. As an example, we apply this formulation to known plane symmetric space–times. We take the Taub's static metric in the interior region whereas Kasner's nonstatic metric in the exterior region.

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).

GRAVITATIONAL COLLAPSE OF STARS AND THE METHODS OF ITS OBSERVATIONS
Odessa Astronomical Publications, 2016 It is present a review of the models of the later stages of stellar evolution and the mechanisms of the generation of neutrinos, charged particles and electromagnetic radiation during the gravitational collapse of stars.
