Overview: Cosmology with the SKAO
Marta Spinelli, Ian Harrison, Richard A. Battye +5
The SKA telescopes will revolutionise our ability to do cosmology at radio wavelengths, via both their own data and in synergy with other wavelengths. SKAO will be the first instru…
Beyond ÎCDM with the SKA Observatory -- II: Unveiling the Secrets of the Early Universe
José Fonseca, Benedict Bahr-Kalus, Mario Ballardini +12
The origins of the universe remain one of the biggest mysteries in modern cosmology. While the Planck satellite has provided a wealth of information about the early universe, there…
Cosmology with HI Intensity Mapping
Laura Wolz, Gabriele Autieri, José Luis Bernal +18
The redshifted spectral emission from neutral hydrogen (HI) at rest wavelength 21 cm can be used as a tracer of large-scale structure and its evolution. Within the HI intensity map…
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…
Overview of 21cm Experiments at high redshift with SKAO
CD Science Working Group, Gianni Bernardi, Daniela Breitman +81
We provide an overview of the eight SKAO Science Book chapters that motivate the Epoch of Reionisation and Cosmic Dawn experiments with SKA-Low. We describe the individual SKA-Low…
Methodological Frontiers in 21-cm Intensity Mapping: the Treatment of Systematics and Foreground Contamination
Marta Spinelli, Matilde Barberi-Squarotti, José Luis Bernal +29
The distribution of neutral hydrogen (HI) in the post-reionization universe traces the cosmic large-scale structure and therefore serves as a powerful cosmological probe. An effici…
