Breakdown of the Newton-Einstein Standard Gravity at Low Acceleration in Internal Dynamics of Wide Binary Stars

Kyu-Hyun Chae

A gravitational anomaly is found at weak gravitational acceleration m s from analyses of the dynamics of wide binary stars selected from the Gaia DR3…

Testing Modified Gravity Theories with Numerical Solutions of the External Field Effect in Rotationally Supported Galaxies

Kyu-Hyun Chae, Federico Lelli, Harry Desmond +2

The strong equivalence principle is violated by gravity theories of Milgromian dynamics (MOND) through the action of the external field effect. We test two different Lagrangian the…

Distinguishing Dark Matter, Modified Gravity, and Modified Inertia with the Inner and Outer Parts of Galactic Rotation Curves

Kyu-Hyun Chae

The missing gravity in galaxies requires dark matter, or alternatively a modification of gravity or inertia. These theoretical possibilities of fundamental importance may be distin…

Numerical Solutions of the External Field Effect on the Radial Acceleration in Disk Galaxies

Kyu-Hyun Chae, Mordehai Milgrom

In MOND (modified Newtonian dynamics)-based theories the strong equivalence principle is generically broken in an idiosyncratic manner, manifested in the action of an "external fie…

Testing the Strong Equivalence Principle. II. Relating the External Field Effect in Galaxy Rotation Curves to the Large-Scale Structure of the Universe

Kyu-Hyun Chae, Harry Desmond, Federico Lelli +2

Theories of modified gravity generically violate the strong equivalence principle, so that the internal dynamics of a self-gravitating system in free fall depends on the strength o…

Continuous dependence of the Cauchy problem for the inhomogeneous nonlinear Schrödinger equation in

JinMyong An, JinMyong Kim, KyuSong Chae

We consider the Cauchy problem for the inhomogeneous nonlinear Schrödinger (INLS) equation \[iu_{t} +Δu=|x|^{-b} f(u),\;u(0)\in H^{s} (\mathbb R^{n} ),\] where , $0…
