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
The authors re‑evaluate data quality control and the treatment of hidden multiple‑star companions in wide‑binary analyses and find that, even with careful modeling, the low‑acceler…
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…
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…
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 $…
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…
