Topological Signatures of AGN Feedback in the Simba Simulations
Ryusei R. Kano, Romeel Davé, Tsutomu T. Takeuchi +1
Active galactic nuclei (AGN) feedback can alter the abundance and spatial distribution of galaxies within large-scale structure. We apply topological data analysis (TDA) to Simba h…
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)…
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…
Exploring the Cosmic Dawn through the 21 cm Forest and High-redshift Radio Sources with the SKA
Junsong Cang, Benedetta Ciardi, Barun Maity +12
The 21~cm forest, seen as absorption features in the spectra of distant radio sources, is produced by intervening neutral hydrogen and offers a direct probe of the neutral intergal…
Application of Machine Learning to 21 cm Cosmology
Hayato Shimabukuro
This chapter reviews applications of machine learning (ML) to redshifted 21 cm cosmology, focusing on cosmic dawn, the Epoch of Reionization, and SKA-Low science. The redshifted 21…
Reconstruction of Reionization Histories from 21 cm Power-Spectrum Evolution with Artificial Neural Networks
Yu-Le Wang, Hayato Shimabukuro
We investigate whether the redshift evolution of the fixed- dimensionless 21 cm power spectrum, , contains sufficient information to reconstruct reionization his…
Inferring population III star properties from the 21-cm global signal
Sho Ukai, Hayato Shimabukuro, Kenji Hasegawa +1
Investigating the properties of the first stars in the universe, known as Population III (Pop~III) stars, is essential, yet it remains an open question. One way to explore these st…
