The K - Band Galaxy Luminosity Function 12
We measured the K-band luminosity function using a complete sample of 4192 morphologically-typed 2MASS galaxies with 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, for H 0 = 100h km s ?1 Mpc ?1 , such that the late-type galaxies slightly dominate the K-band lum...
متن کاملThe K band galaxy luminosity functions of three massive high redshift clusters of galaxies
The K band galaxy luminosity functions of three massive high redshift clusters of galaxies. ABSTRACT K band observations of the galaxy populations of three high redshift (z = 0.8–1.0), X-ray selected, massive clusters are presented. The observations reach a depth of K ≃ 21.5, corresponding to K * + 3.5 mag. The evolution of the galaxy properties are discussed in terms of their K band luminosity...
متن کاملSe p 20 02 The Hawaii - AAO K - band Galaxy Redshift Survey — Paper I : The Local K - band Luminosity Function
We present the K-band local luminosity function derived froma sample of 1056 bright (K < 15) K-selected galaxies from the Hawaii-AAO K-band redshift survey. The Hawaii-AAO K-band redshift survey covers 4 equatorial fields with a total area of 8.22 deg 2. We derive both the non-parametric and Schechter luminosity function from our data, and determine M * (K) = −23.70 ± 0.08 + 5 log 10 (h), α = −...

We present K–band luminosity functions for galaxies in a heterogeneous sample of 38 clusters at 0.1 < z < 1. Using infrared–selected galaxy samples which generally reach 2 magnitudes fainter than the characteristic galaxy luminosity L, we fit Schechter functions to background–corrected cluster galaxy counts to determine K as a function of redshift. Because of the magnitude limit of our data, th...
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...
