Constraints on a fifth force from the stellar orbits around the central supermassive black hole of the Milky Way
Predrag Jovanović, Duško Borka, Vesna Borka Jovanović
Here we investigate a possible presence of a fifth force at the Galactic Center (GC), and its potential influence on the stellar orbits around the central supermassive black hole o…
The comparison of an optical and X-ray counterpart of subparsec supermassive binary black holes
P. Jovanović, S. Simić, V. Borka Jovanović +2
In this paper, we study and compare the optical and X-ray counterparts of subparsec supermassive black hole binaries (SMBHBs). With that aim, we simulated the profiles of optical s…
Improvement of graviton mass constraints using GRAVITY's detection of Schwarzschild precession in the orbit of S2 star around the Galactic Center
Predrag Jovanović, Vesna Borka Jovanović, Duško Borka +1
Here we study possible improvements of the existing constraints on the upper bound of graviton mass by the analysis of the stellar orbits around the SMBH at the GC in the framework…
Spectral index distribution over radio lobes of 4C 14.11 using astrophysical data in FITS format
V. Borka Jovanović, D. Borka, A. Arsenić +1
The goal of this paper is to investigate the flux and spectral index distribution of FR II radio galaxy 4C 14.11. We focused on the distribution of flux and spectral indices over t…
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…
