Observational Frontiers in the post-EoR 21-cm Intensity Mapping: Lessons from the SKA Pathfinders
Khandakar Md Asif Elahi, Somnath Bharadwaj, Philip Bull +21
The 21-cm line from neutral hydrogen has long been recognised as a promising tracer of the large-scale structure of the Universe. The line is weak however, making individual galaxy…
The Tianlai-WIYN North Celestial Cap Redshift Survey
Reza Ansari, Gabriela A. Marques, John P. Marriner +13
We present the results of a small, low redshift spectroscopic survey of galaxies within 3 degrees of the North Celestial Pole (NCP) selected using V-band photometry obtained from t…
Tackling Challenges in 21cm Global Spectrum Experiment: the Impact of Ionosphere and Beam Distortion
Yue Wang, Xin Wang, Shijie Sun +3
The HI 21cm global signal from the Cosmic Dawn and the Epoch of Reionization (EoR) offers critical insights into the evolution of our Universe. Yet, its detection presents signific…
On Measuring the 21 cm Global Spectrum of the Cosmic Dawn with an Interferometer Array
Xin Zhang, Bin Yue, Yuan Shi +2
We theoretically investigate the recovery of global spectrum (monopole) from visibilities (cross-correlation only) measured by the interferometer array and the feasibility of extra…
