Estimating the Parameters of Extended Gravity Theories with the Schwarzschild Precession of S2 Star
D. Borka, V. Borka Jovanović, S. Capozziello +2
After giving a short overview of previous results on constraining of Extended Gravity (EG) by stellar orbits, we discuss the Schwarzschild orbital precession of S2 star assuming th…
Testing the Galactic Centre potential with S-stars
Alexander F. Zakharov
Two groups of astronomers used the large telescopes Keck and VLT for decades to observe trajectories of bright stars near the Galactic Centre. Based on results of their observation…
Constraints on a tidal charge of the supermassive black hole in M87* with the EHT observations in April 2017
Alexander F. Zakharov
More than two years ago the Event Horizon Telescope collaboration presented the first image reconstruction around the shadow for the supermassive black hole in M87*. It gives an op…
Influence of bulk mass distribution on orbital precession of S2 star in Yukawa gravity
P. Jovanović, D. Borka, V. Borka Jovanović +1
In this study we investigate possible applications of observed S2 orbit around Galactic Center for constraining the Yukawa gravity at scales in the range between several tens and s…
