We continue to explore the relationship between the total number of globular clusters (GCs),
N GC, and the central black hole mass, M•, in spiral galaxies. We present here results for the …

The current standard cosmological model is based on the normalized Friedmann equation
1= Ω M+ Ω Λ+ Ω K, where Ω M is the mass density of dark and baryonic matter, Ω Λ the …

An accurate computational method is presented for determining the mass distribution in a
mature spiral galaxy from a given rotation curve by applying Newtonian dynamics for an …

From observational data and our theoretical analysis, we demonstrate that a scaling law can
be written for all organized matter utilizing the Schwarzschild condition, describing …

In the ΛCDM cosmological model, based on observations of supernovae Ia, the cosmic dark
energy density is assumed to be Ω Λ∼ 0.70 and the gravitational mass density is assumed …

We present an efficient, robust computational method for modeling the Newtonian dynamics
for rotation curve analysis of thin-disk galaxies. With appropriate mathematical treatments …

According to the Standard cosmological model, our universe needs a significant amount of
dark matter (DM), about six times that of the usual baryonic matter, besides an even larger …

This book provides a mathematical and numerical analysis of many problems which lead to
paradoxes in contemporary cosmology, in particular, the existence of dark matter and dark …

Spiral galaxies are studied using a simple global disc model as a means for approximate
determination of mass profiles. Based on rotation curves and the amount of gas (H i+ He) …

Recent astrophysical data indicates that dark matter shows a controversial behaviour in
galaxy cluster collisions. In case of the notorious Bullet cluster, dark matter component of the …
