AGN Feedback in Galaxy Clisters - Controlling Cooling Flows in Galaxy Clusters by Momentum-driven AGN Jets
Synopsis According to the hierarchical structure formation model, massive structures like galaxy clusters are formed due to the gravitational collapse of initial density perturbations and their subsequent mergers. ... -
Cooling, heating and gas evolution in the circumgalactic medium
The Universe at large scales consists of gravitationally bound dark matter halos. Ordinary gas inside the halos emits and also absorbs the radiation from background sources leaving distinct signatures for multi-wavelength ... -
Fermi Bubbles and Galactic Outflows in Circumgalactic Medium
Galactic outflows play an important role in the formation and evolution of galaxies by regulating the star formation rate (SFR) within them and by throwing out metals into the intergalactic medium (IGM). They are key to ... -
Galactic cosmic rays from star clusters and nearby supernovae remnants
Cosmic rays (CRs) are high-energy particles, predominantly originating from outside the Earth’s atmosphere. These particles, ranging from protons to heavier nuclei, propagate through space at nearly the speed of light, ... -
Geometrical and Topological Properties of CMB Polarization Fields
Cosmic Microwave Background (CMB) is a relic from the early Universe. It was generated due to the physical processes in the early Universe during an epoch known as the recombination or decoupling epoch. The CMB has highly ... -
Simulations and modeling of multiphase gas in the circumgalactic medium
The circumgalactic medium (CGM) plays a critical role in galactic evolution, serving as a complex gaseous environment that hosts most of a galaxy's baryonic matter and mediates intricate gas flows. This thesis presents ... -
A Study of Superbubbles in the ISM : Break-Out, Escape of LYC Photons and Molecule Formation
(2018-02-16)Multiple coherent supernova explosions (SNe) in an OB association can produce a strong shock that moves through the interstellar medium (ISM). These shocks fronts carve out hot and tenuous regions in the ISM known as ...
