Probing the large-scale structure with 21cm-galaxy cross-bispectrum: Estimates from simulations and forecasts for upcoming cosmological surveys

Leon Noble, Suman Majumdar, Matteo Viel +7

The paper investigates the 21 cm–galaxy cross‑bispectrum using simulated galaxy evolution models and forecasts its detectability with upcoming Euclid‑like galaxy surveys and SKA‑Mi…

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…

Asking Fast Radio Bursts for More than Reionization History

Abinash Kumar Shaw, Raghunath Ghara, Paz Beniamini +2

We propose different estimators to probe the intergalactic medium (IGM) during epoch of reionization (EoR) using the dispersion measure () of the fast radio bursts. We co…

The Effect of Large Optical Depths on the Non-Gaussian 21-cm signal from Cosmic Dawn

Iffat Nasreen, Kanan K. Datta, Abinash K. Shaw +6

During the Cosmic Dawn (CD), the HI 21-cm optical depth ( ) in the intergalactic medium can become significantly large. Consequently, the second and higher-order terms of
