Magnetically arrested advective accretion flows around black holes and their implications to ultraluminous X-ray sources and blazars
Black hole (BH) accretions are very powerful sources of energy in the universe. In accretion phenomena, the surrounding gas spirals down towards the central BH and forms a disc or quasi-spherical structure based on the ... -
Nonlinear and Geometric Properties of Accreting Compact Sources Based on Spectral and Timing Analyses
We study the spectro-temporal properties of the black hole X-ray binaries (BHXBs) GRS 1915+105 and IGR J17091-3624 with data from RXTE, Chandra and XMM-Newton. From the analysis result, we propose models of accretion ... -
Numerical studies of shock oscillations and MRI turbulence in accretion
In this thesis, we study two different aspects of accretion flows- (i) quasi-periodic oscillations (QPOs) seen in the light curves of X-ray binaries as a possible consequence of shock oscillations, (ii) global 3D ideal ... -
Spectro-temporal signatures of accretion flows around Galactic Black Holes
A system of two stars in which one is a black hole (BH) is referred to as a black hole binary (BHB). In a BHB, it is possible to have mass transfer from the secondary star (companion star) to the primary black hole. ...
