Stability of black hole accretion disks
Agnieszka Janiuk, Ranjeev Misra, Bozena Czerny +1
We discuss the issues of stability of accretion disks that may undergo the limit-cycle oscillations due to the two main types of thermal-viscous instabilities. These are induced ei…
Black Hole spin dependence of general relativistic multi-transonic accretion close to the horizon
Tapas K. Das, Sankhasubhra Nag, Swathi Hegde +7
We introduce a novel formalism to investigate the role of the spin angular momentum of astrophysical black holes in influencing the behaviour of low angular momentum general relati…
Quasi-star jets as unidentified gamma-ray sources
Bozena Czerny, Agnieszka Janiuk, Marek Sikora +1
Gamma-ray catalogs contain a considerable amount of unidentified sources. Many of these are located out of the Galactic plane and therefore may have extragalactic origin. Here we a…
