A Detection of Cosmological 21 cm Emission from CHIME in Cross-correlation with eBOSS Measurements of the Lyman- Forest
CHIME Collaboration, Mandana Amiri, Kevin Bandura +28
We report the detection of 21 cm emission at an average redshift in the cross-correlation of data from the Canadian Hydrogen Intensity Mapping Experiment (CHIME) wi…
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…
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…
Using the Sun to Measure the Primary Beam Response of the Canadian Hydrogen Intensity Mapping Experiment
CHIME Collaboration, Mandana Amiri, Kevin Bandura +27
We present a beam pattern measurement of the Canadian Hydrogen Intensity Mapping Experiment (CHIME) made using the Sun as a calibration source. As CHIME is a pure drift scan instru…
Discovery of a 21 cm absorption system at z=2.327 with CHIME
CHIME Collaboration, Mandana Amiri, Arnab Chakraborty +19
We report the detection of a new 21 cm absorption system associated with the radio source NVSS J164725+375218 at a redshift of z=2.327, identified through a pilot survey conducted…
Detection of Cosmological 21 cm Emission with the Canadian Hydrogen Intensity Mapping Experiment
CHIME Collaboration, Mandana Amiri, Kevin Bandura +30
We present a detection of 21-cm emission from large-scale structure (LSS) between redshift 0.78 and 1.43 made with the Canadian Hydrogen Intensity Mapping Experiment (CHIME). Radio…
