| Citation | Visiting Professor of Astronomy, University of Sussex. Professor Pagel is distinguished for his penetrating analyses of the abundances of the elements as displayed in astronomical spectra of stars and gaseous nebula, and the relationship of those abundances to theories of the origin of the elements and of their redistribution through a galaxy. The Anglo-Australian and La Palma telescopes have enabled him to extend this work to gaseous nebulae in other galaxies. He has analysed his own and other people's measurements of Helium in the most metal-deficient galaxies known. He showed that the primordial Helium abundance is as low as 23+/-1% by mass. By comparing this result with the predictions of Big Bang nucleosynthesis he deduced that there could not be more than 3 neutrino types and that the new lower lifetime of the neutron was probably correct. These predictions have since been confirmed by experiments. |
