Reliability of in-band and broadband spectral index measurement: systematic study of the effect of signal to noise for uGMRT data
Md Rashid, Nirupam Roy, J. D. Pandian +4
Low radio frequency spectral index measurements are a powerful tool to distinguish between different emission mechanisms and, in turn, to understand the nature of the sources. Besi…
Towards -cm intensity mapping at with uGMRT using the tapered gridded estimator -- IV. Wideband analysis
Khandakar Md Asif Elahi, Somnath Bharadwaj, Srijita Pal +8
We present a Wideband Tapered Gridded Estimator (TGE), which incorporates baseline migration and variation of the primary beam pattern for neutral hydrogen (${\rm H\hspace{0.5mm}}{…
Calibration requirement for Epoch of Reionization 21-cm signal observation -- III. Bias and variance in uGMRT ELAIS-N1 field power spectrum
Saikat Gayen, Rashmi Sagar, Sarvesh Mangla +6
Power spectrum of \HI 21-cm radiation is one of the promising probes to study large scale structure of the universe and understand galaxy formation and evolution. The presence of f…
