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
galaxies.
If you are looking for the original IRSA
2MASS LGA Service, it can be found
here. 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"
using IRSA's
Cutouts Service, 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
2MASS XSC
all-sky 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.
