Methodological Frontiers in 21-cm Intensity Mapping: the Treatment of Systematics and Foreground Contamination
Marta Spinelli, Matilde Barberi-Squarotti, José Luis Bernal +29
The distribution of neutral hydrogen (HI) in the post-reionization universe traces the cosmic large-scale structure and therefore serves as a powerful cosmological probe. An effici…
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}}{…
A demonstration of the effect of fringe-rate filtering in the Hydrogen Epoch of Reionization Array delay power spectrum pipeline
Hugh Garsden, Philip Bull, Mike Wilensky +94
Radio interferometers targeting the 21cm brightness temperature fluctuations at high redshift are subject to systematic effects that operate over a range of different timescales. T…
The angular power spectrum measurement of the Galactic synchrotron emission in two fields of the TGSS survey
Samir Choudhuri, Somnath Bharadwaj, Sk. Saiyad Ali +3
Characterizing the diffuse Galactic synchrotron emission at arcminute angular scales is needed to reliably remove foregrounds in cosmological 21-cm measurements. The study of this…
