MOND-like behavior in the Dirac-Milne universe -- Flat rotation curves and mass/velocity relations in galaxies and clusters
Gabriel Chardin, Yohan Dubois, Giovanni Manfredi +2
We show that in the Dirac-Milne universe (a matter-antimatter symmetric universe where the two components repel each other), rotation curves are generically flat beyond the charact…
Structure formation in a Dirac-Milne universe: comparison with the standard cosmological model
Giovanni Manfredi, Jean-Louis Rouet, Bruce N. Miller +1
The presence of complex hierarchical gravitational structures is one of the main features of the observed universe. Here, structure formation is studied both for the standard ($Λ\r…
Cosmological structure formation with negative mass
Giovanni Manfredi, Jean-Louis Rouet, Bruce Miller +1
We construct a family of models with negative gravitational mass in the context of Newtonian gravity. We focus in particular on a model that reproduces the features of the so-calle…
Thermodynamics of a one-dimensional self-gravitating gas with periodic boundary conditions
Pankaj Kumar, Bruce N. Miller, Dan Pirjol
We study the thermodynamical properties of a one-dimensional gas with one-dimensional gravitational interactions, and placed in a uniform mass background. Periodic boundary conditi…
Lyapunov spectra of Coulombic and gravitational periodic systems
Pankaj Kumar, Bruce N. Miller
We compute Lyapunov spectra for Coulombic and gravitational versions of the one-dimensional systems of parallel sheets with periodic boundary conditions. Exact time evolution of ta…
Dynamics of Coulombic and Gravitational Periodic Systems
Pankaj Kumar, Bruce N. Miller
We study the dynamics and the phase-space structures of Coulombic and self-gravitating versions of the classical one-dimensional 3-body system with periodic boundary conditions. We…
