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…

First Results from HERA Phase II

The HERA Collaboration, Zuhra Abdurashidova, Tyrone Adams +83

We report the first upper limits on the power spectrum of 21-cm fluctuations during the Epoch of Reionization and Cosmic Dawn from Phase II of the Hydrogen Epoch of Reionization Ar…

A demonstration of the effect of fringe-rate filtering in the Hydrogen Epoch of Reionization Array delay power spectrum pipeline

Hugh Garsden, Philip Bull, Mike Wilensky +94

Radio interferometers targeting the 21cm brightness temperature fluctuations at high redshift are subject to systematic effects that operate over a range of different timescales. T…

Structure evolution with cosmic backgrounds from radio to far infrared

Carlo Burigana, Tiziana Trombetti, Matteo Bonato +2

Cosmic background radiation, both diffuse and discrete in nature, produced at different cosmic epochs before and after recombination, provides key information on the evolution of c…

matvis: A matrix-based visibility simulator for fast forward modelling of many-element 21 cm arrays

Piyanat Kittiwisit, Steven G. Murray, Hugh Garsden +95

Detection of the faint 21 cm line emission from the Cosmic Dawn and Epoch of Reionisation will require not only exquisite control over instrumental calibration and systematics to a…
