Estimating the parameters of Hybrid Palatini gravity model with the Schwarzschild precession of S2, S38 and S55 stars: case of bulk mass distribution
D. Borka, V. Borka Jovanović, V. N. Nikolić +2
We estimate the parameters of Hybrid Palatini gravity model with the Schwarzschild precession of S-stars, specifically of S2, S38 and S55 stars. We also take into account case of b…
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…
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…
Possible effects of Hybrid Gravity on stellar kinematics in elliptical galaxies
V. Borka Jovanović, D. Borka, P. Jovanović +1
We use the Fundamental Plane of Elliptical Galaxies to constrain the so-called Hybrid Gravity, a modified theory of gravity where General Relativity is improved by further degrees…
Fundamental plane of elliptical galaxies in gravity: the role of luminosity
Vesna Borka Jovanović, Predrag Jovanović, Duško Borka +1
The global properties of elliptical galaxies are connected through the so-called fundamental plane of ellipticals, which is an empirical relation between their parameters: effectiv…
The First Spectroscopically Resolved Sub-parsec Orbit of a Supermassive Binary Black Hole
E. Bon, P. Jovanović, P. Marziani +6
One of the most intriguing scenarios proposed to explain how active galactic nuclei are triggered involves the existence of a supermassive binary black hole system in their cores.…
