Galaxy photometry and cosmology

Lecture Notes in Physics, 1985
A brief review is presented of the current understanding of galaxy photometry as related to cosmology. Attention is paid to the conclusions about spectral evolution of galaxies that can be derived from the deepest faint galaxy samples currently available. Some typical results are discussed.

Photometry of southern galaxies

Publications of the Astronomical Society of the Pacific, 1982
Multiaperture photoelectric V and (B-V) measurements of 74 southern galaxies are presented. The diaphragms of the indicated diameters, the number of nights on which observations were obtained, and the estimated internal accuracy of the data are also indicated. Thirty-five of the galaxies have no prior published photoelectric data, and several should be

Handling of ‘Galaxy’ Photometry

1975
The properties of photographic images present certain well-known difficulties if accurate photometry is to be carried out. In order to derive light, curves of variable stars to the limit of long-exposure photographs, means have been specially developed to convert ‘Galaxy’ measures of 607 stars, including 150 photoelectric standards, on a total of 93 ...
