Revisiting Data Quality Control and Multiple-star Modeling in Wide Binary Gravity Tests: Confirmation of MOND-type Gravitational Anomaly at Low Acceleration
Kyu-Hyun Chae, Youngsub Yoon
Wide binary stars provide natural laboratories for directly probing gravity in the low-acceleration regime, as dark matter inferred from any viable gravity has negligible effects o…
The Baryonic Faber-Jackson Relation and Fundamental Plane of Galaxy Groups, Elliptical Galaxies, and Dwarf Galaxies
Yong Tian, Federico Lelli, Marcel S. Pawlowski +7
The baryonic Faber-Jackson relation (BFJR) links the baryonic mass of pressure-supported systems to their mean velocity dispersion. For elliptical galaxies, the BFJR is thought to…
Probing the nature of gravity in the low-acceleration limit: wide binaries of extreme separations with perspective effects
Youngsub Yoon, Yong Tian, Kyu-Hyun Chae
Recent statistical analyses of wide binaries have revealed a boost in gravitational acceleration with respect to the prediction by Newtonian gravity at low internal accelerations $…
Bayesian Inference of Gravity through Realistic 3D Modeling of Wide Binary Orbits: General Algorithm and a Pilot Study with HARPS Radial Velocities
Kyu-Hyun Chae
When 3D relative displacement and velocity between the pair in a gravitationally-bound system are precisely measured, the six measured quantities at one p…
Low-Acceleration Gravitational Anomaly from Bayesian 3D Modeling of Wide Binary Orbits: Methodology and Results with Gaia Data Release 3
Kyu-Hyun Chae
Isolated wide binary stars provide natural laboratories to directly probe gravity for Newtonian acceleration m s. Recent statistical analyses of…
Measurements of the Low-Acceleration Gravitational Anomaly from the Normalized Velocity Profile of Gaia Wide Binary Stars and Statistical Testing of Newtonian and Milgromian Theories
Kyu-Hyun Chae
Low-acceleration gravitational anomaly is investigated with a new method of exploiting the normalized velocity profile of wide binary stars as a function…
A critical review of recent GAIA wide binary gravity tests
X. Hernandez, Kyu-Hyun Chae, A. Aguayo-Ortiz
Over the last couple of years, the appearance of the third data release from the {\it Gaia} satellite has triggered various wide binary low acceleration gravity tests. Wide binarie…
Robust Evidence for the Breakdown of Standard Gravity at Low Acceleration from Statistically Pure Binaries Free of Hidden Companions
Kyu-Hyun Chae
It is found that Gaia DR3 binary stars selected with stringent requirements on astrometric measurements and radial velocities naturally satisfy Newtonian dynamics without hidden cl…
