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…
Using strong gravitational lensing to probe the post reionization \HI power spectrum
Urvashi Arora, Prasun Dutta
Probing statistical distribution of the neutral hydrogen (\HI) using the redshifted 21-cm hyperfine-transition spectral line holds the key to understand the formation and evolution…
Evidence of large scale energy cascade in the spiral galaxy NGC 5236
Meera Nandakumar, Prasun Dutta
Turbulence plays an important role in the structure and dynamics of the galaxy and influences various processes therein including star formation. In this work, we investigate the l…
Calibration Requirements for Epoch of Reionization 21-cm signal observations -- I. Effect of time-correlated gains
Jais Kumar, Prasun Dutta, Nirupam Roy
The residual gain errors add to the systematics of the radio interferometric observations. In case of the high dynamic range observations, these systematic effects dominates over t…
The study of the angular and spatial distribution of radio selected AGNs and star-forming galaxies in the ELAIS N1 field
Arnab Chakraborty, Prasun Dutta, Abhirup Datta +1
The cosmic evolution of bias of different source populations with underlying dark matter density field in post reionization era can shed light on large scale structures. Studying t…
