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…
Astrophysical constraints from future measurements of the kinetic Sunyaev-Zel'dovich power spectrum
Lisa McBride, Adélie Gorce, Marian Douspis +8
High-precision measurements of the Cosmic Microwave Background (CMB) will soon allow for the unprecedented detection of small-scale secondary anisotropies, such as the kinetic Suny…
Generative Models of 21cm EoR Lightcones with 3D Scattering Transforms
Ian Hothi, Erwan Allys, Benoit Semelin +1
The 21cm signal from the Epoch of Reionization (EoR) is observed as a three-dimensional data set known as a lightcone, consisting of a redshift (frequency) axis and two spatial sky…
Combining summary statistics with simulation-based inference for the 21 cm signal from the Epoch of Reionization
Benoit Semelin, Romain Mériot, Ashutosh Mishra +1
The 21 cm signal from the Epoch of Reionization will be observed with the up-coming Square Kilometer Array (SKA). SKA should yield a full tomography of the signal which opens the p…
