Caption: PART OF THE CLUB The influential astronomer Allan Sandage (left), known for his work on galaxy formation and other topics, encouraged Rubin in her work--even breaking Palomar regulations by inviting her to observe there.
It truly was the most memorable astronomical event of my life and, whenever I turn my own puny instrument on that giant, I fondly remember that night and the kindness and humor of Allan Sandage.
Allan Sandage's history of the observatory is the first of five volumes that celebrate the institution's century of scientific sponsorship.
Freedman, while some of the best-known supernova-based [H.sub.0] values have come from a second group led by veteran cosmologist Allan Sandage. The latter group has been advocating a low Hubble constant of 58 [+ or -] 6, and it uses different methods for selecting and measuring the brightness of Cepheid variables than those adopted by the Key Project.
He includes Fred Hoyle, Alan Guth, and Freeman Dyson yet leaves out George Gamow, Allan Sandage, and Wendy Freedman.
A seminal 1956 Astronomical Journal article on galaxy redshifts by Milton Humason, Nicholas Mayall, and Allan Sandage listed eight members of Abell 2065 with redshifts of about 21,500 kilometers per second.
Allan Sandage has described cosmology as "the search for two numbers." He meant the Hubble constant, [H.sub.0] (the cosmic expansion rate), and the deceleration parameter, [q.sub.0] (the slowing down or speeding up of that expansion).
Cosmologists have become so preoccupied by [H.sub.0] and [q.sub.0] that in 1970, Allan Sandage, Hubble's successor at Mount Wilson Observatory, titled a Physics Today article "Cosmology: A Search for Two Numbers." On those numbers a lot rides.
For the really big picture, I turn to The Carnegie Atlas of Galaxies by Allan Sandage and John Bedke.
MORE THAN three decades have passed since Allan Sandage announced in 1960 that he and Thomas Matthews had identified a strange source of radio emission that, in visible light, looked like a faint star.
On one hand was Allan Sandage who, having had Edwin Hubble's mantle placed on his shoulders, spent a great deal of his early scientific career working on the problem.
