A direct detection of neutral hydrogen intensity mapping on Mpc scales at and
Sourabh Paul, Zhaoting Chen, Mario G. Santos +1
We report the detection of the cosmological power spectrum using the intensity mapping signal from 21-cm emission of neutral hydrogen (HI), derived from interferometric observation…
A framework to mitigate patchy reionization contamination on the primordial gravitational wave signal
Divesh Jain, Tirthankar Roy Choudhury, Suvodip Mukherjee +1
One of the major goals of future cosmic microwave background (CMB) -mode polarization experiments is the detection of primordial gravitational waves through an unbiased measurem…
Characterization of the John A. Galt telescope for radio holography with CHIME
Alex Reda, Tristan Pinsonneault-Marotte, Meiling Deng +21
The Canadian Hydrogen Intensity Mapping Experiment (CHIME) will measure the 21 cm emission of astrophysical neutral hydrogen to probe large scale structure at redshifts z=0.8-2.5.…
The Hydrogen Intensity and Real-time Analysis eXperiment: 256-Element Array Status and Overview
Devin Crichton, Moumita Aich, Adam Amara +97
The Hydrogen Intensity and Real-time Analysis eXperiment (HIRAX) is a radio interferometer array currently in development, with an initial 256-element array to be deployed at the S…
HI intensity mapping with the MIGHTEE survey: power spectrum estimates
Sourabh Paul, Mario G. Santos, Junaid Townsend +5
Intensity mapping (IM) with neutral hydrogen is a promising avenue to probe the large scale structure of the Universe. In this paper, we demonstrate that using the 64-dish MeerKAT…
CMB constraints on a physical model of reionization
Tirthankar Roy Choudhury, Suvodip Mukherjee, Sourabh Paul
We study constraints on allowed reionization histories by comparing predictions of a physical semi-numerical model with secondary temperature and polarization anisotropies of the c…
