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.

--------------------------------------------------------------------------------
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 (6): 'Z' if listed in Large Galaxy Atlas (Jarrett et al.
2003AJ....125..525J 2003AJ....125..525J) based on the parameter cc_flg=Z in 2MASX

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 1977A&A....54..661T), Cepheids
(Freedman et al. 2001ApJ...553...47F 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 2006AJ....131.1361K), and surface brightness
fluctuations (Tonry et al. 2001ApJ...546..681T 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'.
