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…

Interpretation of 21 cm Auto Power Spectrum Measurement at by the Canadian Hydrogen Intensity Mapping Experiment

CHIME Collaboration, Mandana Amiri, Kevin Bandura +21

Observations with the Canadian Hydrogen Intensity Mapping Experiment (CHIME) have been used to measure the 21 cm intensity mapping auto power spectrum, at , over a frequen…

The Squeezed Bispectrum from CHIME HI Emission and Planck CMB Lensing: Current Sensitivity and Forecasts

CHIME Collaboration, Arnab Chakraborty, Matt Dobbs +18

Line intensity mapping using atomic hydrogen (HI) has the potential to efficiently map large volumes of the universe if the signal can be successfully separated from overwhelmingly…

Detection of the Cosmological 21 cm Signal in Auto-correlation at z ~ 1 with the Canadian Hydrogen Intensity Mapping Experiment

CHIME Collaboration, Mandana Amiri, Kevin Bandura +36

We present the first detection of the cosmological 21 cm intensity mapping signal in auto-correlation at z ~ 1 with the Canadian Hydrogen Intensity Mapping Experiment (CHIME). Usin…

Measurement of the Dispersion$\unicode{x2013}$Galaxy Cross-Power Spectrum with the Second CHIME/FRB Catalog

Haochen Wang, Kiyoshi Masui, Shion Andrew +18

The dispersion of extragalactic fast radio bursts (FRBs) can serve as a powerful probe of the diffuse plasma between and surrounding galaxies, which contains most of the Universe's…

Demonstration of hybrid foreground removal on CHIME data

Haochen Wang, Kiyoshi Masui, Kevin Bandura +15

The main challenge of 21 cm cosmology experiments is astrophysical foregrounds which are difficult to separate from the signal due to telescope systematics. An earlier study has sh…

The Contribution of Radio Galaxy Contamination to Measurements of the Sunyaev-Zel'dovich Decrement in Massive Galaxy Clusters at 140 GHz with Bolocam

Jack Sayers, Tony Mroczkowski, Nicole G. Czakon +13

We describe in detail our characterization of the compact radio source population in 140 GHz Bolocam observations of a set of 45 massive galaxy clusters. We use a combination of 1.…
