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…
Comparison of MOND and Verlinde's emergent gravity in dwarf spheroidals
Youngsub Yoon, Sanghyeon Han, Ho Seong Hwang
We apply Modified Newtonian Dynamics (MOND) and Verlinde's emergent gravity separately to calculate the radial accelerations in 23 dwarf spheroidals. Then, we compare them with the…
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 $…
Understanding the Radial Acceleration Relation of Dwarf Galaxies with Emergent Gravity
Sanghyeon Han, Ho Seong Hwang, Youngsub Yoon
We examine whether the radial acceleration relation (RAR) of dwarf galaxies can be explained by Verlinde's emergent gravity. This is the extension of arXiv:2206.11685v3, which exam…
