Mond and Cosmology

I review various ideas on MOND cosmology and structure formation beginning with non-relativistic models in analogy with Newtonian cosmology. I discuss relativistic MOND cosmology in the context of Bekenstein’s theory and propose an alternative biscalar effective theory of MOND in which the acceleration parameter, a0 is identified with the cosmic time derivative of a matter coupling scalar field...

The MOND Fundamental Plane

Modified Newtonian dynamics (MOND) has been shown to be able to fit spiral galaxy rotation curves as well as giving a theoretical foundation for empirically determined scaling relations, such as the Tully-Fisher law, without the need for a dark matter halo. As a complementary analysis, one should investigate whether MOND can also reproduce the dynamics of early-type galaxies (ETGs) without dark...

Magellanic Stream in MOND

The dynamics of Magellanic Stream (MS) as a series of clouds extended from the Magellanic Clouds (MCs) to the south Galactic pole is affected by the distribution and the amount of matter in the Milky Way (MW). We calculate the gravitational effect of the Galactic disk on MS in the MOdified Newtonian Dynamics (MOND) frame work and compare with the observations of the radial velocity. Here we con...

Rereading Ludwig Boltzmann

Ludwig Boltzmann is one of the first physicists who brought probability and statistical considerations into physics. Particularly famous is his statistical explanation of the second law of thermodynamics. However, Boltzmann’s ideas on the relationship between the thermodynamical properties of macroscopic bodies and their microscopic mechanical constitution, and the role of probability in this r...
