    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

    Published 2018
    “…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. …”

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

    Published 2022-11-01
    “…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

    Published 2023-01-01
    “…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). …”

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

    Published 2024-01-01
    “…Here, we demonstrate that binary disruption is ineffective and instead we propose that two additional dynamical processes play dominant roles: (1) tidal disruption of main-sequence stars by neutron stars and (2) gravitational collapse of heavy white dwarf binary merger remnants. …”

    Exploring Primordial Curvature Perturbation on Small Scales with the Lensing Effect of Fast Radio Bursts by Huan Zhou, Zhengxiang Li, Zong-Hong Zhu

    Published 2024-01-01
    “…Since primordial black holes (PBHs) could form in the very early Universe through the gravitational collapse of primordial density perturbations, constraints on the PBH could encode much information on primordial fluctuations. …”

    A new large-scale gravitational complex discovered in the Gulf of Squillace (central Mediterranean): tectonic implications by Giacomo Mangano, Silvia Ceramicola, Tiago M. Alves, Massimo Zecchin, Dario Civile, Anna Del Ben, Salvatore Critelli

    Published 2023-09-01
    “…Movement slowed down in the Calabrian (middle Pleistocene) and continued until the present day at a lower rate of 0.1 mm/year. Gravitational collapse of the Squillace Complex correlates with discrete contractional/transpressional events affecting the Calabrian region, which caused basin shortening and the temporary arrest of Calabrian Arc migration. …”

    Deep seismic structure of the Tonga subduction zone: Implications for mantle hydration, tectonic erosion, and arc magmatism by Contreras-Reyes, E, Grevemeyer, I, Watts, A, Flueh, E, Peirce, C, Moeller, S, Papenberg, C

    Published 2011
    “…Extension in the outer fore-arc is evidenced by (1) trenchward-dipping normal faults and (2) the presence of a giant scarp (∼2 km offset and several hundred kilometers long) indicating gravitational collapse of the outermost fore-arc block. In addition, the contact between the subducting slab and the overriding arc crust is only 20 km wide, and the mantle wedge is characterized by low velocities of ∼7.5 km/s, suggesting upper mantle serpentinization or the presence of melts frozen in the mantle.…”

    Tectonic evolution of the central Annapurna Range, Nepalese Himalayas by Hodges, K, Parrish, R, Searle, M

    Published 1996
    “…Geologic evidence for rapid, two-way transitions between contraction and extension in the Annapurna Range indicates that extensional deformation in convergent settings does not only represent gravitational collapse at the end of an orogenic cycle; it also appears to be an important factor in mountain range development.…”
