Aspects of gravitational clustering and structure formation in the Universe
Swati Gavas
The distribution of galaxies, halo abundance, and peculiar velocities are influenced by non-linear gravitational interactions, making the study of non-linear evolution crucial for…
Universality of Halo Shape and its Morphological Evolution across Cosmic Time
Ayan Nanda, Nishikanta Khandai, J. S. Bagla +1
We investigate the evolution of dark matter halo shapes in cosmological N-body simulations both in scale free Einstein-De Sitter (EdS) and CDM cosmologies. We compute the axis…
A dynamical systems perspective on the thermodynamics of late-time cosmology
Dipayan Mukherjee, Harkirat Singh Sahota, Swati Gavas
A thermodynamic description of cosmological spacetimes may provide insights into the fundamentals of the cosmic evolution that remain otherwise obscure, similar to `black hole ther…
On the origin of transient features in cosmological N-Body Simulations
J. S. Bagla, Swati Gavas
We study the effect of gravitational clustering at small scales on larger scales by studying mode coupling between virialised halos. We build on the calculation by Peebles (1974) w…
Dispersion in the Hubble-Lemaître constant measurements from gravitational clustering
Swati Gavas, J S Bagla, Nishikanta Khandai
Measurements of the Hubble-Lemaître constant () require us to estimate the distance and recession velocity of galaxies independently. Gravitational clustering that leads to t…
