LGA Data Atlas
The high sensitivity and angular resolution of
the 2MASS Large Galaxy Atlas (LGA)
images allows closer inspection of diverse
stellar populations, large-scale structures
such as spirals, bulges, warps and bars, star
formation regions and evolution of galaxies.
This image atlas represents the first uniform,
all-sky, view of galaxies as seen in the
near-infrared wavelength window that is most
sensitive to the dominant mass component of
If you are looking for the original IRSA
2MASS LGA Service, it can be found
. JPEG images, photometric information
and NED connectivity are available there. This
LGA Data Atlas serves multiple FITS image files
covering a wide area of the sky.
Also available are LGA image "cutouts
, which is a general tool to create single or multiple small FITS
(and JPEGs) image cutouts of datasets archived at IRSA.
LGA images are represented as overlays in red on the
ISSA all-sky composite image above. Either type in a coordinate or click on any
red region to get a close-up of the area; the size of the search is adjustable.
