The redshift evolution of escape fraction of hydrogen ionizing photons from galaxies
Vikram Khaire, Raghunathan Srianand, Tirthankar Roy Choudhury +1
Using our cosmological radiative transfer code, we study the implications of the updated QSO emissivity and star formation history for the escape fraction (f_esc) of hydrogen ioniz…
Cosmic reionization after Planck
Sourav Mitra, T. Roy Choudhury, Andrea Ferrara
Cosmic reionization holds the key to understand structure formation in the Universe, and can inform us about the properties of the first sources, as their star formation efficiency…
Measuring the equation of state of the high-z intergalactic medium using curvature statistics
Hamsa Padmanabhan, R. Srianand, T. Roy Choudhury
Using hydrodynamical simulations, we explore the use of the mean and percentiles of the curvature distribution function to recover the equation of state of the high- ($2 < z < 4…
Reionization and Galaxy Formation in Warm Dark Matter Cosmologies
Pratika Dayal, Tirthankar Roy Choudhury, Volker Bromm +1
We compare model results from a semi-analytic (merger-tree based) framework for high-redshift (z ~ 5-20) galaxy formation against reionization indicators, including the Planck elec…
