Cosmology with post-EoR 21 cm Intensity Mapping surveys: power spectrum measurements in the last decade
Réza Ansari, Xuelei Chen, Albert Stebbins +1
The technique of 21 cm intensity mapping (IM) is emerging as a possible, cost-effective method to supplement optical surveys to map the large-scale structure, and extend their reds…
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…
Needlet Karhunen-Loève (NKL): A Method For Cleaning Foregrounds From 21cm Intensity Maps
John Podczerwinski, Peter Timbie
This paper introduces a technique called NKL, which cleans both polarized and unpolarized foregrounds from HI intensity maps by applying a Karhunen-Loève transform on the needlet c…
