Apoastron Shift Constraints on Dark Matter Distribution at the Galactic Center
A. F. Zakharov, A. A. Nucita, F. De Paolis +1
The existence of dark matter (DM) at scales of few pc down to pc around the centers of galaxies and in particular in the Galactic Center region has been considered…
Conformal Cosmological Model Test with Distant SNIa Data
A. F. Zakharov, A. A. Zakharova, V. N. Pervushin
Assuming that supernovae type Ia (SNe Ia) are standard candles one could use them to test cosmological theories. The Hubble Space Telescope team analyzed 186 SNe Ia (Riess et al. (…
Solar system constraints on R gravity
A. F. Zakharov, A. A. Nucita, F. De Paolis +1
Recently, gravitational microlensing has been investigated in the framework of the weak field limit of fourth order gravity theory. However, solar system data (i.e. planetary perio…
Hamiltonian General Relativity in Finite Space and Cosmological Potential Perturbations
B. M. Barbashov, V. N. Pervushin, A. F. Zakharov +1
The Hamiltonian formulation of general relativity (GR) is considered in finite space-time and a specific frame of reference given by the diffeo-invariant components of the Fock sim…
Different Types of Fe K_αLines from Radiating Annuli near Black Holes
Alexander F. Zakharov, Serge V. Repin
Recent X-ray observations of microquasars and Seyfert galaxies reveal the broad emission lines in their spectra, which can arise in the innermost parts of accretion disks. A theore…
Microlensing of the Fe K line and the X-ray continuum
L. C. Popovic, P. Jovanovic, E. Mediavilla +4
The observed enhancement of the Fe K line in three gravitationally lensed QSOs (MG J0414+0534, QSO 2237+0305, H1413+117) is interpreted in terms of microlensing, even when equiv…
