MAXI J1820+070: A rapidly spinning black hole with a small disk truncation in the soft state and warm corona layers
Th. V. Papavasileiou, T. S. Kosmas, O. Kosmas +1
Our study seeks to address the debate over the spin of MAXI J1820+070 through broadband spectral modeling of NICER/NuSTAR observations obtained during the soft state. We further co…
A simplified approach for reproducing fully relativistic spectra in X-ray binary systems: Application to Cygnus X-1
Th. V. Papavasileiou, O. Kosmas, T. S. Kosmas
General relativistic effects are strong near the black hole of an X-ray binary and significantly impact the total energy released at the innermost accretion disk's region. Our goal…
Modeling Simulated Emissions from Galactic Binary Stars
Theodora V. Papavasileiou, Odysseas T. Kosmas, Ioannis Sinatkas
Relativistic plasma flows from the jets of black hole binary systems consist the environment of multiple particle production and radiation emission including neutrinos and gamma-ra…
Relativistic Magnetized Astrophysical Plasma Outflows in Black-Hole Microquasars
Theodora Papavasileiou, Odysseas Kosmas, Ioannis Sinatkas
Recently, microquasar jets have aroused the interest of many researchers focusing on the astrophysical plasma outflows and various jet ejections. In this work, we concentrate on th…

High energy neutrino and gamma-ray emission in the jets of the microquasar M33 X-7
D. A. Papadopoulos, Th. V. Papavasileiou, T. S. Kosmas
In this work, after testing the reliability of our algorithms through numerical simulations on the well-studied SS 433 Galactic microquasar, we focus on neutrino and -ray emissi…
Astrophysical magnetohydrodynamical outflows in the extragalactic binary system LMC X-1
Th. V. Papavasileiou, D. A. Papadopoulos, T. S. Kosmas
In this work, at first we present a model of studying astrophysical flows of binary systems and microquasars based on the laws of relativistic magnetohydrodynamics. Then, by solvin…
