Probing early universe through redshifted 21-cm signal: Modelling and observational challenges
Abinash Kumar Shaw, Arnab Chakraborty, Mohd Kamran +8
The redshifted 21-cm radiation from the atomic hydrogen (HI) provides an excellent direct probe to study the evolution of HI in IGM and thus reveal the nature of the first luminous…
Towards 21-cm Intensity Mapping at with uGMRT using the Tapered Gridded Estimator I: Foreground Avoidance
Srijita Pal, Kh. Md. Asif Elahi, Somnath Bharadwaj +8
The post-reionization neutral hydrogen (HI) 21-cm intensity mapping signal holds the potential to probe the large scale structures, study the expansion history and cons…
The first power spectrum limit on the 21-cm signal of neutral hydrogen during the Cosmic Dawn at z=20-25 from LOFAR
B. K. Gehlot, F. G. Mertens, L. V. E. Koopmans +19
Observations of the redshifted 21-cm hyperfine line of neutral hydrogen from early phases of the Universe such as Cosmic Dawn and the Epoch of Reionization promise to open a new wi…
Upper limits on the 21-cm Epoch of Reionization power spectrum from one night with LOFAR
A. H. Patil, S. Yatawatta, L. V. E. Koopmans +25
We present the first limits on the Epoch of Reionization (EoR) 21-cm HI power spectra, in the redshift range , using the Low-Frequency Array (LOFAR) High-Band Antenna (…
