Machine Learning and the SKA for Cosmic Dawn and the Epoch of Reionization

Anshuman Acharya, Michele Bianco, Daniela Breitman +18

When operational, the SKA will generate unprecedented amounts of data and provide exquisite sensitivity for 21 cm tomography of Cosmic Dawn (CD) and the Epoch of Reionization (EoR)…

Foreground Characterization and Mitigation in the Observations of the CD/EoR with the SKA

Philip Bull, Jacob Burba, Emilio Ceccotti +20

The Square Kilometre Array (SKA), with its unprecedented sensitivity, frequency coverage, and large collecting area, is poised to revolutionize our understanding of the Cosmic Dawn…

Studying Ionosphere Using SKA-Low and SKA-Mid

Abhirup Datta, Samit Kumar Pal, Sarvesh Mangla +4

The Earth's ionosphere introduces systematic effects that limit the performance of radio interferometers operating at low frequencies (\,GHz). These ionospheric effects…

Cosmology with Multi-Wavelength Line Intensity Mapping Synergies in the SKAO Era

Debanjan Sarkar, Suman Majumdar, Chandra Shekhar Murmu +21

Line intensity mapping (LIM) has emerged as a powerful tool for surveying the large-scale structure of the Universe across cosmic time by measuring spatial fluctuations in the cumu…

Cosmology with Intensity Mapping via Statistics Beyond the Power Spectrum in the SKAO Era

Suman Majumdar, Debanjan Sarkar, Leon Noble +38

The cosmological distribution of neutral hydrogen (HI) during the post-reionization era is highly non-Gaussian due to the underlying non-linear structure formation, complex galaxy…

Inferring Cosmology and Astrophysics from the High-redshift 21cm Signal with SKA-Low

Anshuman Acharya, Satadru Bag, Sabrina Berger +29

The Square Kilometre Array's low frequency telescope (SKA-Low) will enable inference of astrophysical and cosmological parameters from the redshifted 21 cm signal, probing the Cosm…

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…

Mitigating residual foregrounds and systematic errors in SKA1-Low AA* EoR observations via Bayesian Gaussian Process Regression

Samit Kumar Pal, Abhirup Datta, Aishrila Mazumder +1

The redshifted 21\,cm line is an emerging tool in observational cosmology that can serve as a direct probe of the intergalactic medium throughout the cosmic timeline. However, the…
