HI intensity mapping with MeerKAT: Calibration pipeline for multi-dish autocorrelation observations

Jingying Wang, Mario G. Santos, Philip Bull +10

While most purpose-built 21cm intensity mapping experiments are close-packed interferometer arrays, general-purpose dish arrays should also be capable of measuring the cosmological…

Single-dish HI Intensity Mapping with the SKAO: Precursor Progress with MeerKAT's Large Area Synoptic Survey (MeerKLASS)

Steven Cunnington, Jingying Wang, Mario G. Santos +16

Using the SKAO to map the intensity of neutral hydrogen's 21cm emission line will be a golden opportunity to constrain models of cosmology. To access the largest cosmological scale…

HI intensity mapping with MeerKAT: power spectrum detection in cross-correlation with WiggleZ galaxies

Steven Cunnington, Yichao Li, Mario G. Santos +13

We present a detection of correlated clustering between MeerKAT radio intensity maps and galaxies from the WiggleZ Dark Energy Survey. We find a detection of the cross-corr…

Radio Frequency Interference from Radio Navigation Satellite Systems: simulations and comparison to MeerKAT single-dish data

Brandon Engelbrecht, Mario G. Santos, José Fonseca +11

Radio Frequency Interference (RFI) is emitted from various sources, terrestrial or orbital, and create a nuisance for ground-based 21cm experiments. In particular, single-dish 21cm…

meer21cm: an Analysis Pipeline and Comprehensive Toolkit for HI Intensity Mapping

Zhaoting Chen, Steven Cunnington, Daniel Tassie +23

We present meer21cm, a comprehensive python package for cosmological data analysis of single-dish HI intensity mapping surveys. This package is simple to use, with a modularised co…
