Tsallis-Cirto Hubble parameter: Explaining DESI data and High redshift Supermassive Black Hole
James C. C. Wong
Phantom dark energy from DESI DR2 BAO [1]-[3] and observations of very high redshift Supermassive Black Holes (SMBH) present two new major challenges in cosmology and astrophysics.…
A Baseline model for Modified Newtonian Mechanics I: The Early Universe
James C. C. Wong, Ray J. Rivers
In modelling galaxy structure formation, neither Cold Dark Matter (CDM) nor canonical Modified Newtonian Dynamics (MOND) (Milgrom [1]) can easily accommodate the appearance of mass…
Variable Modified Newtonian Mechanics VIII: Ultra faint dwarfs in Milky Way
James Chi Chung Wong
Velocity dispersions of Ultra faint dwarf (UFD) galaxies are observed to deviate significantly from the Baryon Tully Fisher Relation of the massive galaxies (BTFR). We propose a so…
Variable Modified Newtonian Mechanics III: Milky Way Rotational Curve
James C. C. Wong
For a point mass residing in an expanding universe, within General Relativity (GR), a new metric [1} is found to lead to a cosmological background dependent MOND-like acceleration…
Variable Modified Newtonian Mechanics IV: Non Rotating Galaxies
James C. C. Wong
At it stands, the model does not anticipate the early emergence of massive galaxies. Canonical Modified Newtonian Dynamics (MOND) seems to fail at late time solar system sc…
