In order to understand the evolution of galaxies, detailed analysis of images plays a key role. During the last years telescopes working at different wavelengths have been imaging the whole sky. One example of this is the Sloan Digital Sky Survey. The generated images provides a wealth of information, publicly available, and hence allowing them to be used by any interested group in the study of their own samples of objects or generation of new samples.

Thumb
This workflow uses astrotaverna artifacts. It creates files by using a template whose keys are replaced by data from a votable. A configuration file is created for every row in the votable. The keys must appear also in the vocabulary file and match column names in the votable. A column in the votable must contain the name of the result configuration file.

Workflow Discovery of Brown Dwarfs mining the 2MASS... (1)

Thumb
Brown dwarfs are objects occupying the gap between the least massive stars and the most massive planets. They are intrinsically faint objects so their detection is not straighforward and, in fact, was almost impossible until the advent of global surveys at deep optical and near-infrared bands like SDSS, 2MASS or DENIS among others. Here we propose to mine the SDSS and 2MASS databases to identify T-type brown dwarfs through an appropriate combination of colours in the optical and the infra-red...
