Constraints on gravity from precession of orbits of S2-like stars: a case of a bulk distribution of mass
Alexander F. Zakharov, Dusko Borka, Vesna Borka Jovanović +1
Here we investigate possible applications of observed stellar orbits around Galactic Center for constraining the R gravity at Galactic scales. For that purpose, we simulated or…
Influence of Microlensing on Spectral Anomaly of Lensed Objects
Sasa Z. Simic, Luka C. Popovic, Predrag Jovanovic
Here we consider the influence of the microlensing on the spectrum of a lensed object taking into account that composite emission is coming from different regions arranged subseque…
Microlensing of the X-ray, UV and optical emission regions of quasars: Simulations of the time-scales and amplitude variations of microlensing events
P. Jovanović, A. F. Zakharov, L. Č. Popović +1
We consider the influence of microlensing on different spectral bands of lensed QSOs. We assumed that the emitting X-ray, UV and optical regions are different in size, but that the…
