Quantifying Ionospheric Effects on Global 21-cm Observations
Emma Shen, Dominic Anstey, Eloy de Lera Acedo +2
We modelled the two major layer of Earth's ionosphere, the F-layer and the D-layer, by a simplified spatial model with temporal variance to study the chromatic ionospheric effects…
Mapping discrete galaxies at cosmic dawn with 21-centimeter observations
Itamar Reis, Rennan Barkana, Anastasia Fialkov
At cosmic dawn, the 21-centimeter signal from intergalactic hydrogen was driven by Lyman- photons from some of the earliest stars, producing a spatial pattern that reflected the…
High-redshift radio galaxies: a potential new source of 21-cm fluctuations
Itamar Reis, Anastasia Fialkov, Rennan Barkana
Radio sources are expected to have formed at high redshifts, producing an excess radiation background above the cosmic microwave background (CMB) at low frequencies. Their effect o…
Photoevaporation of Minihalos during Cosmic Reionization: Primordial and Metal-Enriched Halos
Riouhei Nakatani, Anastasia Fialkov, Naoki Yoshida
The density distribution of the inter-galactic medium is an uncertain but highly important issue in the study of cosmic reionization. It is expected that there are abundant gas clo…
Tight Constraints on the Excess Radio Background at from LOFAR
R. Mondal, A. Fialkov, C. Fling +13
The ARCADE2 and LWA1 experiments have claimed an excess over the Cosmic Microwave Background (CMB) at low radio frequencies. If the cosmological high-redshift contribution to this…
Quantiles as Robust Probes of Non-Gaussianity in 21-cm Images
Alon Banet, Rennan Barkana, Anastasia Fialkov +1
The early epoch in which the first stars and galaxies formed is among the most exciting unexplored eras of the Universe. A major research effort focuses on probing this era with th…
