On the Origin of the Ly Damping Wing in Galaxies at : Explorations using the NINJA Simulations
Sukanya Mallik, Raghunathan Srianand, Nishikanta Khandai
Ly damping wing measurements of galaxies at with the JWST provide a powerful probe of the Epoch of Reionization. We combine the large-scale cosmological hydrodyn…
The Stellar Mass Function of Gas-Rich Galaxies and the Underlying Scaling Relation in the Local Universe
Tanya Tripty, Nishikanta Khandai, Saili Dutta +1
We estimate the Galaxy Stellar Mass Function (GSMF) of HI gas-rich galaxies using the 100\% ALFALFA () catalog, of which have optical counterparts in the Sloan Digi…
NISER-IUCAA New Simulations of JWST GAlaxies and Quasars(NINJA): Properties of galaxies at
Ranit Behera, Raghunathan Srianand, Nishikanta Khandai +1
We present the NINJA suite of cosmological hydrodynamical simulations developed to investigate galaxy formation and evolution at in the era of JWST. Using our fiducia…
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…
Forecasting properties of detectable massive binary black hole mergers in the era of space based gravitational-wave detectors
Sourabh Magare, Abhinav Roy, Shasvath J. Kapadia +2
Gravitational waves (GWs) from massive black hole (MBH) mergers will provide a novel way to probe the high-redshift universe and are key to understanding galactic dynamics and evol…
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…
