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…
POLAR-II: modeling star formation history of galaxies on the 21-cm signal from Epoch of Reionization
Qing-Bo Ma, Raghunath Ghara, Benedetta Ciardi +6
Galaxies may suffer some starburst and quenched periods in their history due to e.g. galaxy mergers and feedback. However, semi-numerical simulations of the Epoch of Reionization (…
Mitigating incoherent excess variance in high-redshift 21 cm observations with multi-output cross-Gaussian process regression
S. Munshi, L. V. E. Koopmans, F. G. Mertens +8
Systematic effects that limit the achievable sensitivity of current low-frequency radio telescopes to the 21 cm signal are among the foremost challenges in observational 21 cm cosm…
The impact of lunar topography on the 21-cm power spectrum for grid-based arrays : Insights for the Dark-ages EXplorer (DEX)
S. Ghosh, L. V. E. Koopmans, C. Brinkerink +17
The Dark Ages (DA) provides a crucial window into the physics of the infant Universe, with the 21-cm signal offering the only direct probe for mapping out the three-dimensional dis…
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…
Velocity fields and turbulence from cosmic filaments to galaxy clusters
Théo Lebeau, Saleem Zaroubi, Nabila Aghanim +2
Galaxy clusters are currently the endpoint of the hierarchical structure formation; they form via the accretion of dark matter and cosmic gas from their local environment. In parti…
