Abstract:
We discuss the results of the relationships between the K-band and
stellar mass, far-infrared luminosities, star formation rate, dust and
gas masses of nearby galaxies computing the bivariate K-band
Luminosity Function (BLF) and bivariate K-band Mass Function (BMF) of
the Herschel Reference Survey (HRS), a volume-limited sample with full
wavelength coverage. We derive the BLFs and BMFs from the K-band and
stellar mass, far-infrared luminosities, star formation rate, dust and
gas masses cumulative distributions using a copula method which is
outlined in detail. The use of the bivariate computed taking into
account the upper limits allows us to derive on a more solid
statistical ground the relationship between the observed physical
quantities.
The analysis shows that the behaviour of the morphological (optically
selected) subsamples is quite different. A statistically meaningful
result can be obtained over the whole HRS sample only from the
relationship between the K-band and the stellar mass, while for the
remaining physical quantities (dust and gas masses, far-IR luminosity
and star formation rate), the analysis is distinct for late-type (LT)
and early-type galaxies (ETG). However, the number of ETGs is small to
perform a robust statistical analysis, and in most of the case results
are discussed only for the LTG subsample. The Luminosity and Mass
Functions (LFs, MFs) of LTGs are generally dependent on the K-band and
the various dependencies are discussed in detail. We are able to
derive the corresponding LFs and MFs and compare them with those
computed with other samples. Our statistical analysis allows us to
characterise the HRS, that, although non homogeneously selected and
partially biased towards low IR luminosities, may be considered as
representative of the local LT galaxy population.
Description:
The HRS is a volume-limited sample (i.e. 15<D<25Mpc) including
late-type galaxies (LTGs) (Sa and later) with 2MASS Kband magnitude 12
mag and early-type galaxies (ETGs) (S0a and earlier) with ≤8.7mag.
Additional selection criteria are high Galactic latitude (b>+55°)
and low Galactic extinction (AB<0.2mag, (Schlegel et al.,
1998ApJ...500..525S 1998ApJ...500..525S)). The sample includes 322 galaxies (260 LTGs and
62 ETGs), and the total volume over an area of 3649 sq.deg. is
4539Mpc3. The selection criteria are fully described in Boselli et
al. (2010, Cat. J/PASP/122/261).
