Astronomical Working Papers
- Description
This section contains almost complete documentation for Hubble's three papers on cepheids (Messier 31, Messier 33, and N.G.C. 6822) published from 1925 to 1929, for his 1930 paper, "The Distribution of Luminosity in Elliptical Nebulae," and for his 1934 paper on the distribution of galaxies in space. Much of the data Hubble compiled in checking Adriaan van Maanen's conclusions concerning the angular rotations of spiral nebulae is also here. There are a few finding charts for clusters of galaxies which were utilized in Hubble's calculation of the velocity-distance relation among extragalactic nebulae. In addition, several star charts and other telescopic photographs have been preserved. The astronomical working papers were organized with the assistance of Dr. Allan Sandage, a former colleague of Hubble's and astronomer at the Carnegie Observatories. The papers have been arranged chronologically according to the particular scientific paper produced from them. The data for each paper is randomly ordered, but the verso of each piece has been numbered in pencil.
