The K-band luminosity function of nearby field galaxies
We present a measurement of the K-band luminosity function (LF) of field galaxies obtained from near-infrared imaging of a sample of 345 galaxies selected from the Stromlo-APM Redshift Survey. The LF is reasonably well fitted over the 10-mag range 226 < MK < 216 by a Schechter function with parameters a 21:16 ^ 0:19; M* 223:58 ^ 0:42 and f* 0:012 ^ 0:008 Mpc, assuming a Hubble constant of...
متن کاملA wide - field K – band survey . The luminosity function of galaxies
We present the first determination of the near-infrared K−band luminosity function of field galaxies from a wide field K−selected redshift survey. The best fit Schechter function parameters are M∗ = −23.12 + 5log(h), α = −0.91, and φ∗ = 1.66 × 10h Mpc. We estimate that systematics are no more than 0.1mag in M∗ and 0.1 in α, which is comparable to the statistical errors on this measurement. Subj...
متن کاملNearby Galaxies in the 2μm All Sky Survey I. K-band Luminosity Functions
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 ...
متن کاملThe UV luminosity function of nearby clusters of galaxies
We present the UV composite luminosity function for galaxies in the Virgo, Coma and Abell 1367 clusters. The luminosity function (LF) is well fitted by a Schechter function with M * UV − 5 log h 75 = −20.75 ± 0.40 and α = −1.50 ± 0.10 and does not differ significantly from the local UV luminosity function of the field. This result is in agreement with recent studies carried out in the Hα and B-...
متن کاملThe K-band Galaxy Luminosity Function
We measured the K-band luminosity function using a complete sample of 4192 morphologically-typed 2MASS galaxies with µ Ks = 20 mag/arcsec 2 isophotal magnitudes 7 < K 20 < 11.25 mag spread over 2.12 str. Early-type (T ≤ −0.5) and late-type (T > −0.5) galaxies have similarly shaped luminosity functions,
