Caldera collapse thresholds correlate with magma chamber dimensions by Nobuo Geshi, Isoji Miyagi, Genji Saito, Chris E. Conway

“…Abstract Explosive caldera-forming eruptions eject voluminous magma during the gravitational collapse of the roof of the magma chamber. Caldera collapse is known to occur by rapid decompression of a magma chamber at shallow depth, however, the thresholds for magma chamber decompression that promotes caldera collapse have not been tested using examples from actual caldera-forming eruptions. …”

Tectonic inversion of compressional structures in the Southern portion of the Paramirim Corridor, Bahia, Brazil by Simone Cerqueira Pereira Cruz, Fernando Flecha Alkmim, Johildo Salomão Figueiredo Barbosa, Ivo Dussin, Luiz César Corrêa Gomes

“…Together, data obtained for the structures associated with the late extensional regimen described in the present study suggest that its nucleation is associated with distal and brittle-ductile sectors of the gravitational collapse zone of Araçuaí-West Congo Orogen.…”

Stirred and shaken: Dynamical behavior of boson stars and dark matter cores by Lorenzo Annulli, Vitor Cardoso, Rodrigo Vicente

“…We also show that the gravitational collapse to a supermassive black hole at the center of a NBS is accompanied by only a small change in the surrounding core. …”

Entanglement Tsunami: Universal Scaling in Holographic Thermalization by Liu, Hong, Suh, Sunok Josephine

“…We consider the time evolution of entanglement entropy after a global quench in a strongly coupled holographic system, whose subsequent equilibration is described in the gravity dual by the gravitational collapse of a thin shell of matter resulting in a black hole. …”

An ALMA view of star formation efficiency suppression in early-type galaxies after gas-rich minor mergers by Van De Voort, F, Davis, T, Matsushita, S, Rowlands, K, Shabala, S, Allison, J, Ting, Y, Sansom, A, Van Der Werf, P

“…These asymmetries support the interpretation that the suppression of the SFE is caused by dynamical effects stabilizing the gas against gravitational collapse. Through kinematic modelling we derive high velocity dispersions and Toomre Q stability parameters for the gas, but caution that such measurements in edge-on galaxies suffer from degeneracies. …”

Ergosphere and shadow of a rotating regular black hole by Sushant G. Ghosh, Muhammed Amir, Sunil D. Maharaj

“…The spacetime singularities in classical general relativity predicted by the celebrated singularity theorems are formed at the end of gravitational collapse. Quantum gravity is the expected theory to resolve the singularity problem but we are now far from it. …”

Physical and morphological characterization of the 19 May 2021 ash cloud deposit at Stromboli (Italy) by Giuseppe Re, Massimo Pompilio, Paola Del Carlo, Alessio Di Roberto

“…Abstract We report on the ash cloud related to the gravitational collapse of a portion of the Stromboli volcano crater rim that occurred on 19 May 2021. …”

The effective theory of gravity and dynamical vacuum energy by Emil Mottola

“…By allowing Λeff to vary rapidly near the 2-surface of a black hole horizon, the proposed EFT of dynamical vacuum energy provides an effective Lagrangian framework for gravitational condensate stars, as the final state of complete gravitational collapse consistent with quantum theory. The possible consequences of dynamical vacuum dark energy for cosmology, the cosmic coincidence problem, and the role of conformal invariance for other fine tuning issues in the Standard Model are discussed.…”

Planetesimal Formation by the Gravitational Instability of Dust Ring Structures by Sanemichi Z. Takahashi, Eiichiro Kokubo, Shu-ichiro Inutsuka

“…We investigate the gravitational instability (GI) of dust ring structures and the formation of planetesimals by their gravitational collapse. The normalized dispersion relation of a self-gravitating ring structure includes two parameters that are related to its width and line mass (the mass per unit length). …”

General classification of charged test particle circular orbits in Reissner–Nordström spacetime by D. Pugliese, H. Quevedo, R. Ruffini

“…These limits play an important role in the study of the coupled electromagnetic and gravitational interactions, and the investigation of the role of the charge in the gravitational collapse of compact objects.…”

Flattened Galaxy Rotation Curves in the Exochronous Metric by Robin Booth

“…Using this new form of the Poisson equation, we derive an analytic expression for gravitational potential as a function of radial distance for a uniform gas cloud undergoing gravitational collapse. We show that this results in a radial velocity profile that provides an excellent fit with commonly observed galaxy rotation curves, and hence fully accounts for the effects previously ascribed to dark matter. …”

The Earth in space: An essay on the origin of the Solar system by S. BURMAN

“…<br />The present day accepted theories are, hence, the monistic ones, and<br />the one particularly favored is the Dust — cloud hypothesis — that the sun<br />condensed into a star due to the gravitational collapse of a massive interstellar<br />gas-cloud, and subsequently gave birth to planets as further evolution<br />of the cloud progressed. …”

Streaming Instabilities in Accreting Protoplanetary Disks: A Parameter Study by Shiang-Chih Wang, Min-Kai Lin

“…For ϵ ≳ 1, maximum dust-to-gas ratios of order 100 are attained, which can be expected to undergo gravitational collapse. Furthermore, even in systems dominated by the classical SI, an accretion flow drives filament formation, without which the disk remains in a state of small-scale turbulence. …”

Single Millisecond Pulsars from Dynamical Interaction Processes in Dense Star Clusters by Claire S. Ye, Kyle Kremer, Scott M. Ransom, Frederic A. Rasio

On the Origin of Quenched but Gas-rich Regions at Kiloparsec Scales in Nearby Galaxies by Tao Jing, Cheng Li

The different feature importance for quenching, as found previously by A. …”
