Gravitational Waves from Gravitational Collapse [PDF]
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 ...

Gravitational collapse of Mount Etna's southeastern flank. [PDF]
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.

Critical Phenomena in Gravitational Collapse [PDF]
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]
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 in Rastall gravity [PDF]
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]
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.

Shearfree cylindrical gravitational collapse [PDF]
We consider diagonal cylindrically symmetric metrics, with an interior representing a general non-rotating fluid with anisotropic pressures. An exterior vacuum Einstein-Rosen spacetime is matched to this using Darmois matching conditions. We show that the matching conditions can be explicitly solved for the boundary values of metric components and ...

On the quantum corrected gravitational collapse [PDF]
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]
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 ...
