Nearby Galaxies in the 2μm All Sky Survey I. K-band Luminosity Functions
نویسنده
چکیده
Differential Ks-band luminosity functions (LFs) are presented for a complete sample of 1613 nearby bright galaxies segregated by visible morphology. The LF for late-type spirals follows a power law that rises towards low luminosities whereas the LFs for ellipticals, lenticulars and bulge-dominated spirals are peaked and decline toward both higher and lower luminosities. Each morphological type (E, S0, S0/a–Sab, Sb–Sbc, Sc–Scd) contributes approximately equally to the overall Ks-band luminosity density of galaxies in the local universe.

Large-scale Structures behind the Milky Way from Near-ir Surveys
About 25% of the optical extragalactic sky is obscured by the dust and stars of our Milky Way. Dynamically important structures might still lie hidden in this zone. Various approaches are presently being employed to uncover the galaxy distribution in the Zone of Avoidance (ZOA) but all suffer from (different) limitations and selection effects. We investigated the potential of using the DENIS NI...
متن کاملNear - infrared imaging and the K − z relation for radio galaxies in the 7 C Redshift Survey
We present K-band imaging of all 49 radio galaxies in the 7C–I and 7C–II regions of the 7C Redshift Survey (7CRS). The low–frequency (151 MHz) selected 7CRS sample contains all sources with flux-densities S151 > 0.5 Jy in three regions of the sky. We combine the K-band magnitudes of the 7CRS radio galaxies with those from the 3CRR, 6CE and 6C⋆ samples to investigate the nature of the relationsh...
متن کاملThe Group Evolution Multiwavelength Study (GEMS): The near-infrared luminosity function of nearby galaxy groups
We present J and K-band luminosity functions (LF) for the Group Evolution Multiwavelength Study (GEMS) sample of 60 nearby groups of galaxies, with photometry from the 2MASS survey. We find that, as seen in B and R-band photometry of a subsample of these groups in our earlier work, the LFs of the X-ray dim groups (LX < 10 erg s) show a depletion of galaxies of intermediate luminosity around MK ...
متن کاملLuminosity and surface brightness distribution of K-band galaxies from the UKIDSS Large Area Survey
We present luminosity and surface-brightness distributions of 40 111 galaxies with K-band photometry from the United Kingdom Infrared Telescope (UKIRT) Infrared Deep Sky Survey (UKIDSS) Large Area Survey (LAS), Data Release 3 and optical photometry from Data Release 5 of the Sloan Digital Sky Survey (SDSS). Various features and limitations of the new UKIDSS data are examined, such as a problem ...
متن کاملHigh-ionization Fe K Emission from Luminous Infrared Galaxies
The Chandra component of the Great Observatories All-Sky LIRG Survey (GOALS) presently contains 44 luminous and ultraluminous infrared galaxies with log (LIR/L⊙) = 11.73−12.57. Omitting 15 obvious AGNs, the other galaxies are, on average, underluminous in the 2-10keV band by 0.7 dex at a given far-infrared luminosity, compared to nearby star-forming galaxies with lower star formation rates. The...
