Towards -cm intensity mapping at with uGMRT using the tapered gridded estimator III: Foreground removal
Khandakar Md Asif Elahi, Somnath Bharadwaj, Srijita Pal +8
Neutral hydrogen (HI) -cm intensity mapping (IM) is a promising probe of the large-scale structures in the Universe. However, a few orders of magnitude brighter foregrounds obs…
Quantifying and mitigating the effect of snapshot interval in light-cone Epoch of Reionization 21-cm simulations
Suman Pramanick, Rajesh Mondal, Somnath Bharadwaj
The Epoch of Reionization (EoR) neutral Hydrogen (HI) 21-cm signal evolves significantly along the line-of-sight (LoS) due to the light-cone (LC) effect. It is important to accurat…
Towards -cm intensity mapping at with uGMRT using the tapered gridded estimator II: Cross-polarization power spectrum
Kh. Md. Asif Elahi, Somnath Bharadwaj, Abhik Ghosh +8
Neutral hydrogen () -cm intensity mapping (IM) offers an efficient technique for mapping the large-scale structures in the universe. We introduce the 'Cross' Tapered G…
The Tracking Tapered Gridded Estimator (TTGE) for the power spectrum from drift scan observations
Suman Chatterjee, Somnath Bharadwaj, Samir Choudhuri +2
Intensity mapping with the redshifted 21-cm line is an emerging tool in cosmology. Drift scan observations, where the antennas are fixed to the ground and the telescope's pointing…
Modelling the energy distribution in CHIME/FRB Catalog-1
Siddhartha Bhattacharyya, Somnath Bharadwaj, Himanshu Tiwari +1
We characterize the intrinsic properties of any FRB using its redshift , spectral index and energy in units of emitted across $2128 - 2848\; {\…
Quantifying the redshift space distortion of the bispectrum III : Detection prospects of the multipole moments
Arindam Mazumdar, Debanjan Sarkar, Somnath Bharadwaj
The redshift space anisotropy of the bispectrum is generally quantified using multipole moments. The possibility of measuring these multipoles in any survey depends on the level of…
