Constraining Non-local Gravity by S2 star orbits
K. F. Dialektopoulos, D. Borka, S. Capozziello +2
Non-local theories of gravity have recently gained a lot of interest because they can suitably represent the behavior of gravitational interaction in the ultraviolet regime. Furthe…
Recovering the fundamental plane of galaxies by gravity
V. Borka Jovanović, S. Capozziello, P. Jovanović +1
The fundamental plane (FP) of galaxies can be recovered in the framework of gravity avoiding the issues related to dark matter to fit the observations. In particular, the po…
SNR radio spectral index distribution and its correlation with polarization: a case study of Lupus Loop
V. Borka Jovanović, P. Jovanović, D. Borka
We use radio-continuum all-sky surveys at 1420 and 408 MHz with the aim to investigate properties of the Galactic radio source Lupus Loop. The survey data at 1435 MHz, with the lin…
Constraining Extended Gravity Models by S2 star orbits around the Galactic Centre
S. Capozziello, D. Borka, P. Jovanović +1
We investigate the possibility to explain theoretically the observed deviations of S2 star orbit around the Galactic Centre using gravitational potentials derived from modified gra…
Spectra of HB 21 supernova remnant: Evidence of spectra flattening at the low frequencies
D. Borka, V. Borka Jovanović, D. Urošević
We use observations of the continuum radio emission at 1420, 820, 408, 34.5 and 22 MHz to estimate the mean brightness temperatures of the HB 21 supernova remnant (SNR) at five fre…
The brightness temperatures of the main Galactic radio-loops at 22 MHz
D. Urošević, V. Borka Jovanović
The average brightness temperatures and surface brightnesses at 22 MHz are derived for the four main Galactic radio-continuum loops (Loops I, II, III and IV, hereafter radio-loops)…
Temperature, brightness and spectral index of the Cygnus radio loop
V. Borka Jovanović, D. Urošević
The estimated brightness of the Cygnus loop supernova remnant (SNR) at 2720, 1420, 820, 408 and 34.5 MHz are presented. The observations of the continuum radio emission are used to…
The Monoceros radio loop: temperature, brightness, spectral index and distance
V. Borka Jovanović, D. Urošević
In this paper we estimated the temperatures and brightnesses of the Monoceros radio loop at 1420, 820 and 408 MHz. Linear spectrum is estimated for mean temperatures versus frequen…
