21-cm hydrogen-line absorption in the spectra of discrete sources
Published online by Cambridge University Press: 14 August 2015
Extract
This paper is a short survey of the results obtained with the Dwingeloo 25-meter radio telescope (beamwidth 0°.56) and the 21-cm receiver on hydrogen-line absorption effects in the spectra of a number of strong point sources. Earlier work on this subject has been done by Hagen, Lilley, and McClain [1], and by Davies and Williams [2]. Some preliminary results of the first part of the present investigation were already published [3].
