Abstract

Abstract: The SKA and its pathfinders will enable studies of Hi emission at higher redshifts than ever before. In moving beyond the local Universe, this will require the use of cosmologically appropriate formulae that have traditionally been simplified to their low-redshift approximations. In this paper, we summarise some of the most important relations for tracing Hi emission in the SKA era, and present an online calculator to assist in the planning and analysis of observations (http://hifi.icrar.org ).
