MOND-like behavior in the Dirac-Milne universe -- Flat rotation curves and mass/velocity relations in galaxies and clusters

no code implementations17 Feb 2021 Gabriel Chardin, Yohan Dubois, Giovanni Manfredi, Bruce Miller, Clément Stahl

We also show that the Dirac-Milne universe, featuring a polarization between its matter and antimatter components, presents a behavior similar to that of MOND (Modified Newtonian Dynamics), characterized by an additional surface gravity compared to the Newtonian case.

Rivers of Gas I.: Unveiling The Properties of High Redshift Filaments

no code implementations4 Jan 2021 Marius Ramsøy, Adrianne Slyz, Julien Devriendt, Clotilde Laigle, Yohan Dubois

At high redshift, the cosmic web is widely expected to have a significant impact on the morphologies, dynamics and star formation rates of the galaxies embedded within it, underscoring the need for a comprehensive study of the properties of such a filamentary network.
