Astronomers and citizen scientists describe 800,000+ galaxies in a new catalog
Astronomers at Lomonosov Moscow State University in cooperation with their French colleagues and with the help of citizen scientists have released “The Reference Catalog of Galaxy Spectral Energy Distributions” (RCSED), which contains value-added information about 800,000 galaxies. The catalog is accessible on the web and its description has been published in the Astrophysical Journal Supplement. ...
RCSED describes properties of 800,000 galaxies derived from the elaborated data analysis. For every galaxy, it presents its stellar composition, brightness at ultraviolet, optical, and near-infrared wavelengths. From RCSED, one can also access galaxy spectra obtained by the Sloan Digital Sky Survey, measurements of spectral lines, and properties determined from them, such as the chemical composition of stars and gas, contained in those galaxies. This makes RCSED the first catalog of its kind, which contains results of detailed homogeneous analysis for such large number of objects. ...
RCSED is really flexible and very easy to use. By simply entering the object name or its coordinates in the search field, the website will provide in a single page all the information referring to that object contained in the catalog. One can also use the catalog through Virtual Observatory applications such as TOPCAT. The RCSED website also provides tutorials ...
