Halo models in modified gravity theories with self-accelerated expansion
, 2012 We investigate the structure of halos in the sDGP (self-accelerating branch of the Dvali-Gavadadze-Porrati braneworld gravity) model and the galileon modified gravity model on the basis of the static and spherically symmetric solutions of the ...

A Fast Forward and Inversion Strategy for Three-Dimensional Gravity Field
Mathematics, 2023 Obtaining a three-dimensional (3D) density distribution within a reasonable time is one of the most critical problems in gravity exploration. In this paper, we present an efficient 3D forward modeling and inversion method for gravity data.

Kinematic-gravity model of geodynamo
Геофизический журнал, 2013 Based on the results of solving the inverse problem of magnetometry and analysis of some known models of the Earth magnetic field generation a model is proposed in which the current producing magnetic field is the vortex motion of positively charged ...

Observational Constraints on Kinetic Gravity Braiding from the Integrated Sachs-Wolfe Effect
, 2012 The cross-correlation between the integrated Sachs-Wolfe (ISW) effect and the large scale structure (LSS) is a powerful tool to constrain dark energy and alternative theories of gravity.

A 200 km suspected impact crater Kotuykanskaya near Popigai, Siberia, in the light of new gravity aspects from EIGEN 6C4, and other data [PDF]
, 2020 We provide arguments in favour of impact origin of a 200 km suspected impact crater Kotuykanskaya near Popigai, Siberia, Russia. We use the gravity aspects (gravity disturbances, the Marussi tensor of the second derivatives of the disturbing geopotential,

International Journal of Modern Physics D, 2023 In this paper, the modified [Formula: see text] gravity theory with the function [Formula: see text] is studied. The action at small coupling [Formula: see text] becomes Einstein–Hilbert action. The bound on the parameter [Formula: see text] from local tests is [Formula: see text] cm2. We find the constant curvature solutions and it was shown that the

2D GRAVITY AND MATRIX MODELS I: 2D GRAVITY [PDF]
International Journal of Modern Physics A, 1994 Some approaches to 2D gravity which have been developed in the last few years are reviewed. They are physical (Liouville) gravity, topological theories and matrix models. Special attention is paid to matrix models and their interrelations with different approaches. Almost all technical details are omitted, but examples are presented.

Remote Sensing, 2020 Currently, seafloor topography inversion based on satellite altimetry gravity data provides the principal means to predict the global seafloor topography. Researchers often use sea surface geoid height or gravity anomaly to predict sea depth in the space

Analogue model for quantum gravity phenomenology
, 2005 So called "analogue models" use condensed matter systems (typically hydrodynamic) to set up an "effective metric" and to model curved-space quantum field theory in a physical system where all the microscopic degrees of freedom are well understood.
