2000PASP..112.1008J Near-Infrared Galaxy Morphology Atlas T. H. JARRETT Infrared Processing and Analysis Center, MS 100-22, California Institute of Technology, Jet Propulsion Laboratory, Pasadena, CA 91125; jarrett@ipac.caltech.edu Received 2000 March 9; accepted 2000 April 18 ABSTRACT. We present a representative sample of near-infrared (1-2 micron) images spanning the Hubble galaxy morphology classification sequence. The images come from the Two Micron All-Sky Survey, with a range in brightness of 7 mag < K_s_ < 13.5 mag, and the morphological classifications from the NASA/IPAC Extragalactic Database. We differentiate between elliptical, normal, and barred spirals, compact, dwarf, peculiar, and active galactic nucleus/Seyfert-type galaxies. This image atlas serves as a qualitative guide to the appearance of galaxies at wavelengths that penetrate the obscuring veil of dust, as well as provides a window to the older population of stars that dominate the observed light at 2 microns, including large-scale bar features. We show that central surface brightness and integrated flux may be used to discriminate spheroid and early-type spirals from late-type spirals. The optical and near-infrared properties are compared.
