A Comparative Analysis To Deal With Missing Spectral Information Caused By RFI In Cosmological HI 21CM Observations
Arnab Chakraborty, Abhirup Datta, Aishrila Mazumder
We investigate the effect of radio-frequency interference (RFI) excision in estimating the cosmological \hi\ 21 cm power spectrum. Flagging of RFI-contaminated channels results in…
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…
Characterizing EoR foregrounds: A study of the Lockman Hole Region at 325 MHz
Aishrila Mazumder, Arnab Chakraborty, Abhirup Datta +4
One of the key science goals for the most sensitive telescopes, both current and upcoming, is the detection of the redshifted 21-cm signal from the Cosmic Dawn and Epoch of Reioniz…
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…
Characterization of unresolved and unclassified sources detected in radio continuum surveys of the Galactic plane
Arnab Chakraborty, Nirupam Roy, Y. Wang +7
The continuum emission from 1 to 2 GHz of The HI/OH/Recombination line survey of the inner Milky Way (THOR) at 18" resolution covers square degrees of the Gala…
21cm Global Signal Extraction: Extracting the 21cm Global Signal using Artificial Neural Networks
Madhurima Choudhury, Abhirup Datta, Arnab Chakraborty
The study of the cosmic Dark Ages, Cosmic Dawn, and Epoch of Reionization (EoR) using the all-sky averaged redshifted HI 21cm signal, are some of the key science goals of most of t…
