Mass distribution of modified Newtonian dynamics within highly flattened galaxies
نویسنده
چکیده
Dynamics of spiral galaxies derived from a given surface mass density has been derived by Toomre in a classic paper. We try to transform the singular elliptic function in the integral into a regular elliptic function. The result makes corresponding numerical evaluations and analytic analysis easier. It is applied to the study of the dynamics of Newtonian system and MOND as well. One shows clearly that careful treatment is needed in dealing with the cut-off of the input data. Explicit examples with simple models are also shown in this paper.

Clusters of galaxies with modified Newtonian dynamics (MOND)
X-ray emitting clusters of galaxies are considered in the context of modified Newtonian dynamics (MOND). I show that self-gravitating isothermal gas spheres are not good representations of rich clusters with respect to the radial gas density distribution as indicated by the X-ray surface brightness. Pure gas spheres with a density distribution described by a β model, as observed, also fail beca...
متن کاملModified Newtonian Dynamics and its Implications
Milgrom has proposed that the appearance of discrepancies between the Newtonian dynamical mass and the directly observable mass in astronomical systems could be due to a breakdown of Newtonian dynamics in the limit of low accelerations rather than the presence of unseen matter. Milgrom’s hypothesis, modified Newtonian dynamics or MOND , has been remarkably successful in explaining systematic pr...
متن کاملGlobal deep-MOND parameter as a theory discriminant.
Different formulations of modified Newtonian dynamics predict somewhat different rotation curves for the same mass distribution. Here I consider a global attribute of the rotation curve that might provide a convenient discriminant between theories when applied to isolated, pure-disk galaxies that are everywhere deep in the modified Newtonian dynamics regime. This parameter is Q ≡ V(2)/V(∞)(2), ...
متن کاملResolving the virial discrepancy in clusters of galaxies with modified Newtonian dynamics
A sample of 197 X-ray emitting clusters of galaxies is considered in the context of Milgrom’s modified Newtonian dynamics (MOND). It is shown that the gas mass, extrapolated via an assumed β model to a fixed radius of 3 Mpc, is correlated with the gas temperature as predicted by MOND (Mg ∝ T ). The observed temperatures are generally consistent with the inferred mass of hot gas; no substantial ...
متن کاملEvaluation of New MOND Interpolating Function with Rotation Curves of Galaxies
The rotation curves of a sample of 46 low- and high-surface brightness galaxies are considered in the context of Milgrom's modi_ed dynamics (MOND) to test a new interpolating function proposed by Zhao et al. (2010) [1] and compare with the results of simple interpolating function. The predicted rotation curves are calculated from the total baryonic matter based on the B-band surface photometry,...
