Large astronomical surveys based on the obtention of images in three or more photometric bands have become widespread in the last decade and have revolutionized the studies of large scale structure and galaxy evolution, among others. Since the development of the Sloan Digital Sky Survey the amount of objects involved in different astronomical analysis have increased from hundreds or thousands to hundreds of thousands or even millions. Such hugh data volumes imposse the constraint of obtaining parameters or performing classification of objects in an automatic manner.

ALAS develops its activities at Instituto de Astrofísica de La Plata (Argentina) and Facultad de Ciencias Astronómicas y Geofísicas of Universidad Nacional de La Plata (Argentina). Our goal is to perform studies of different astronomical (both galactic and extragalactic) objects using the available data of several photometric surveys, applying techniques of analysis of big data and comparing the results with those of numerical simulations. The data that we are using at the moment comes from:

S-PLUS

J-PLUS

J-PAS

DESI Legacy Imaging Surveys

Eagle

Illustris-TNG
