The Epoch of Reionization (EoR) marks the period in the universe's history where the neutral hydrogen (HI) in the intergalactic medium became ionized by the …
As the first galaxies and stars formed in the universe, their ultraviolet radiation ionized neutral hydrogen around them, creating bubbles of ionized gas. This time …
This thesis is concerned with understanding features of holography in de-Sitter (dS) and Minkowski space. We give bulk-boundary mapping in dS at large N using …
Galaxy clusters are the largest gravitationally bound structures in the universe. Their enormous scale makes them the perfect environment to host cosmological phenomena that are …
Dark matter is by nature extremely difficult to detect. The only force we are certain it interacts with is gravity, making gravitational studies a key …
Accurately measuring the masses of galaxy clusters is necessary if we are to use galaxy clusters as dark matter and dark energy probes. Gravitational lensing …
