First multi-redshift limits on post-Epoch of Reionization (post-EoR) 21 cm signal from z = 1.96 - 3.58 using uGMRT
Arnab Chakraborty, Abhirup Datta, Nirupam Roy +8
Measurement of fluctuations in diffuse HI 21 cm background radiation from the post-reionization epoch (z < 6) is a promising avenue to probe the large-scale structure of the Univer…
Intensity mapping of post-reionization 21-cm signal and its cross-correlations as a probe of gravity
Chandrachud B. V. Dash, Tapomoy Guha Sarkar, Anjan Kumar Sarkar
We propose the intensity mapping of the redshifted HI 21-cm signal from the post-reionization epoch as a cosmological probe of gravity. We consider the Hu-Sawicki class of $…
Using Artificial Neural Networks to extract the 21-cm Global Signal from the EDGES data
Madhurima Choudhury, Atrideb Chatterjee, Abhirup Datta +1
The redshifted 21-cm signal of neutral Hydrogen is a promising probe into the period of evolution of our Universe when the first stars were formed (Cosmic Dawn), to the period wher…
A consistent and robust measurement of the thermal state of the IGM at from a large sample of Ly forest spectra: Evidence for late and rapid HeII reionization
Prakash Gaikwad, Raghunathan Srianand, Martin G. Haehnelt +1
We characterise the thermal state of the intergalactic medium (IGM) in ten redshift bins in the redshift range with a sample of 103 high resolution, high S/N Ly$α…
CMB constraints on a physical model of reionization
Tirthankar Roy Choudhury, Suvodip Mukherjee, Sourabh Paul
We study constraints on allowed reionization histories by comparing predictions of a physical semi-numerical model with secondary temperature and polarization anisotropies of the c…
Alignment of Radio Galaxy Axes using FIRST Catalogue
Mohit Panwar, Prabhakar, Pritpal Kaur Sandhu +2
We study the alignment of radio galaxies axes using the FIRST catalogue. we impose several cuts in order to select the candidates which are most likely to be free of systematic bia…
