Magnetically arrested advective accretion flows around black holes and their implications to ultraluminous X-ray sources and blazars

Mondal, Tushar

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 ...
Morphology and topology of cosmological fields during the Epoch of Reionization

Kapahtia, Akanksha

In this thesis we have introduced a real space morphological tool, Contour Minkowski tensor (CMT) to analyse the 21cm brightness temperature field from EoR. We showed that the size and shape information of structures ...
Understanding Multi-Wavelength Signatures of Galactic Outflows Through 3-D Simulations

Vijayan, Aditi

Evolution of galaxies is a phenomenon that affects the formation and composition of galaxies, and the intergalactic medium. It is mediated by processes that establish a symbiotic relationship between a galaxy and the ...
