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…

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…
