A Geometrical Test of the Cosmological Energy Contents Using the Lyman-alpha Forest

Abstract

In this Letter we explore a version of the test of cosmological geometry proposed by Alcock & Paczyński (1979), using observations of the Lyman-α forest in the spectra of close quasar pairs. By comparing the correlations in absorption in one quasar spectrum with correlations between the spectra of neighboring quasars one can determine the relation of the… (More)
