Dark halos and Tully-Fisher relation testing modified gravity
A. Amekhyan, S. Sargsyan
We involve the galactic halo observational data to test the weak field General Relativity involving the cosmological constant. Using the data for 15 hydrogen (Hi) VLA super spirals…
Observational scalings testing modified gravity
A. Amekhyan, S. Sargsyan, A. Stepanian
We consider different observational effects to test modified gravity approach involving the cosmological constant in the common description of the dark matter and the dark energy.…
Galactic sparsity and -gravity
A. Amekhyan, S. Sargsyan, A. Stepanian
The sparsity parameter for clusters of galaxies is obtained in the context of -gravity. It is shown that, the theoretical estimated values are within the reported error limits o…
Rotating baryonic dark halos
F. De Paolis, A. V. Gurzadyan, A. A. Nucita +8
Galactic halos are of great importance for our understanding of both the dark matter nature and primordial non-Gaussianity in the perturbation spectrum, a powerful discriminant of…
On the role of dust in the microwave emission of galactic halos
A. Amekhyan, S. Sargsyan, A. Stepanian
The contribution of the thermal dust component in galactic halo rotation is explored based on the microwave data of Planck satellite. The temperature asymmetry of Doppler nature re…
Messier 81's Planck view vs its halo mapping
V. G. Gurzadyan, F. De Paolis, A. A. Nucita +8
This paper is a follow-up of a previous paper about the M82 galaxy and its halo based on Planck observations. As in the case of M82, so also for the M81 galaxy a substantial North-…
