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.

Causal structure of singularity in non-spherical gravitational collapse [PDF]
European Physical Journal C: Particles and Fields, 2022 We investigate here the final state of gravitational collapse of a non-spherical and non-marginally bound dust cloud as modeled by the Szekeres spacetime.

Gravitational collapse of Mount Etna's southeastern flank. [PDF]
Sci Adv, 2018 Gravitational collapse of Mount Etna’s SE flank: New seafloor geodetic data capture active displacement of underwater volcanic flank. The southeastern flank of Etna volcano slides into the Ionian Sea at rates of centimeters per year.

Gravitational collapse in Rastall gravity [PDF]
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 ...

Gravitational collapse in SYK models and Choptuik-like phenomenon [PDF]
Journal of High Energy Physics, 2019 SYK model is a quantum mechanical model of fermions which is solvable at strong coupling and plays an important role as perhaps the simplest holographic model of quantum gravity and black holes.

On the quantum corrected gravitational collapse [PDF]
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.

Matter and gravitons in the gravitational collapse [PDF]
Physics Letters B, 2016 We consider the effects of gravitons in the collapse of baryonic matter that forms a black hole. We first note that the effective number of (soft off-shell) gravitons that account for the (negative) Newtonian potential energy generated by the baryons is ...

Gravitational Collapse in Gravity's Rainbow [PDF]
, 2015 In this paper, we will analyze the gravitational collapse in the framework of gravity's rainbow. We will demonstrate that the position of the horizon for a particle inside the black hole depends on the energy of that particle.

Regular Black Holes: Towards a New Paradigm of Gravitational Collapse [PDF]
Springer Series in Astrophysics and Cosmology, 2022 The collapse of astrophysically significant bodies generates, under suitable conditions, black holes. Since one expects the generator of the black hole to be a rotating body, the black hole will also rotate.
