Q2237+0305 in X-rays: spectra and variability with XMM-Newton
E. V. Fedorova, V. I. Zhdanov, C. Vignali +1
X-ray observations of gravitationally lensed quasars may allow us to probe the inner structure of the central engine of a quasar. Observations of Q2237+0305 (Einstein Cross) in X-r…
Exact Solutions of the Equations of Relativistic Hydrodynamics Representing Potential Flows
Maxim S. Borshch, Valery I. Zhdanov
We use a connection between relativistic hydrodynamics and scalar field theory to generate exact analytic solutions describing non-stationary inhomogeneous flows of the perfect flu…
Non-metric Generalizations of Relativistic Gravitational Theory and Observational Data Interpretation
A. N. Alexandrov, I. B. Vavilova, V. I. Zhdanov
We discuss theoretical formalisms concerning with experimental verification of General Relativity (GR). Non-metric generalizations of GR are considered and a system of postulates i…
Angular Correlation Function of Quasars from SDSS DR3
G. Yu. Ivashchenko, V. I. Zhdanov
We estimate the two-point angular correlation function (CF) of quasars from SDSS DR3 using a special method of comparison random catalog generation. The best-fit value for the CF p…
Anomalous Fluctuations in Observations of Q0957+561 A,B: Smoking Gun of a Cosmic String?
R. Schild, I Masnyak, B. Hnatyk +1
We report the detection of anomalous brightness fluctuations in the multiple image Q0957+561 A,B gravitational lens system, and consider whether such anomalies have a plausible int…
