Paul Wild and His Investigation of the H-Line

Conference paper
Part of the Astrophysics and Space Science Proceedings book series (ASSSP)

Abstract

Paul Wild is best remembered for the major contributions he made to solar radio astronomy. Less well known is his contribution to the Australian work on the 1,420 MHz hydrogen emission line. This short communication draws attention to this work, in the context of the early research on the H-line carried out by staff from the C.S.I.R.O.’s Division of Radiophysics.

I am grateful to Associate Professor Wayne Orchiston and Professor Bruce Slee for commenting on the manuscript. I would also like to acknowledge the assistance of Kathryn Brennan from the National Archives of Australia for her help in accessing archival material, and the CSIRO Astronomy and Space Science Division for providing the image which was used to generate Figure 1.
