Abstract
ABSTRACTWe present a representative sample of near‐infrared (1–2 μm) 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<Ks<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 μm, 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.
