ADC_Keywords: Galaxies, nearby ; Photometry, infrared ; Cross identifications Keywords: galaxies: bulges - galaxies: elliptical and lenticular, cD - galaxies: formation - galaxies: luminosity function, mass function - galaxies: spiral - infrared: galaxies Abstract: 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 toward 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. Type averaged bulge/disk ratios are used to subtract the disk component leading to the prediction that the Ks-band LF for bulges is bimodal with ellipticals dominating the high luminosity peak, comprising 60% of the bulge luminosity density in the local universe with the remaining 40% contributed by lenticulars and the bulges of spirals. Overall, bulges contribute 30% of the galaxy luminosity density at Ks in the local universe with spiral disks making up the remainder. If bulge luminosities indicate central black hole (BH) masses, then our results predict that the BH mass function is also bimodal. File Summary:

Notes on table1.dat: Nearby galaxies were identified using HYPERLEDA, that provides access to the Principal Galaxy Catalog (hereafter PGC; Paturel et al. 2003, Cat. VII/237). The 2MASS (XSC; Jarrett et al. 2000, Cat. VII/233) counterparts of the PGC galaxies were identified on the basis of positional coincidence. Every attempt has been made to identify all known galaxies with K≤10mag, Vgsr≤3000km/s, and |b|>10deg.

Note (1): The galaxies are ordered by absolute K magnitude. Note (2): Taken from the 2MASS XSC based on the peak pixel (Jarrett et al. 2000, Cat. VII/233). Note (3): Measured within the 20mag/arcsec2 elliptical isophote, parameter kmk20fe in the 2MASS XSC (Cat. VII/233). The photometric uncertainty in the magnitude is typically 3%. Note (4): Computed using the distance, Dist (h=0.75). Note (5): From Paturel et al. (2003, Cat. VII/237). Note (6): 'Z' if listed in Large Galaxy Atlas (Jarrett et al. 2003AJ....125..525J) based on the parameter cc_flg=Z in 2MASX (Cat. VII/233) Note (7): Provided by Tully (2007, private communication). Note (8): Tully et al. (2008, Cat. J/ApJ/676/184) have recently quantified the peculiar velocities for nearby galaxies utilizing redshift independent distances based on the following methods: the Tully-Fisher relation (Tully & Fisher 1977A&A....54..661T), Cepheids (Freedman et al. 2001ApJ...553...47F), the luminosity of stars at the tip of the red giant branch (Karachentsev et al. 2004, Cat. J/AJ/127/2031 and 2006AJ....131.1361K), and surface brightness fluctuations (Tonry et al. 2001ApJ...546..681T). These methods have yielded quality distances, with distance modulus uncertainties <0.1mag, for 591 nearby (Vgsr≤3000km/s) galaxies of which 302 are included in the K10/3000 sample, and marked by 'q'.
