2MASS Large Galaxy Atlas (LGA) Overview
LGA Overview LGA Primary Data Access LGA Summaries LGA Cutouts LGA Catalog


The 2MASS Large Galaxy Atlas (LGA) is a collection of custom-made mosaics and additional data products for 649 extended objects, mostly galaxies. This image atlas represents the first uniform, all-sky, view of galaxies as seen in the near-infrared (2MASS JHKs) wavelength windows that are most sensitive to the dominant stellar mass component of galaxies. The images allow close inspection of diverse stellar populations, large-scale structures such as spirals, bulges, warps and bars, and star formation regions of galaxies.
