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…

Hydrogen Epoch of Reionization Array (HERA) Phase II Deployment and Commissioning

Lindsay M. Berkhout, Daniel C. Jacobs, Zuhra Abdurashidova +93

This paper presents the design and deployment of the Hydrogen Epoch of Reionization Array (HERA) phase II system. HERA is designed as a staged experiment targeting 21 cm emission m…

matvis: A matrix-based visibility simulator for fast forward modelling of many-element 21 cm arrays

Piyanat Kittiwisit, Steven G. Murray, Hugh Garsden +95

Detection of the faint 21 cm line emission from the Cosmic Dawn and Epoch of Reionisation will require not only exquisite control over instrumental calibration and systematics to a…

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…
