The present paper contains the investigations with respect to the optical appearance,
redshift distribution, and observed energy flux of the thin accretion disk described by the …

In this work, we investigate the MOdified Gravity (MOG) theory for dynamics of the Universe
and compare the results with the Lambda cold dark matter (ΛCDM) cosmology. We study the …

In the past few decades, various versions of modified gravity theories were proposed to
mimic the effect of dark matter. Compared with the conventional Newtonian or relativistic …

The effects of cosmological expansion on quantum bosonic states are investigated, using
quantum information theory. In particular, a generic Bogoliubov transformation of bosonic …

We analyze the existing rotation-curve data of the Milky Way and M31 galaxies that extend
to very large distances and low accelerations. We find a systematic downward trend in the …

We use S-stars observations to constrain a phenomenological Yukawa-like gravitational
potential whose deviations from General Relativity are parametrized by two couplings, the …

ABSTRACT NGC1277 is a compact but massive lenticular galaxy that shows no signs of the
presence of dark matter. We find that this galaxy's behaviour is consistent not only with …

We investigate the contributions of the Friedmann–Lemaître–Robertson–Walker metric of
the standard cosmology as an asymptotic boundary condition on the first-order …

A covariant modified gravity (MOG) is formulated by adding to general relativity two new
degrees of freedom, a scalar field gravitational coupling strength G= 1/χ and a gravitational …

The effects of cosmological expansion on quantum bosonic states are investigated, using
