Abstract:
We present the distribution of a statistical sample of nearby galaxies
in the κ-space
({kappa1}∝logM, κ2∝log(Ie)3*M/L,
κ3∝M/L).
Our study is based on near-IR (H-band: {lamdba}=1.65µm)
observations, for the first time comprising early- and late-type
systems. Our data confirm that the mean effective dynamical
mass-to-light ratio M/L of the E+S0+S0a galaxies increases with
increasing effective dynamical mass M, as expected from the existence
of the Fundamental Plane relation. Conversely, spiral and Im/BCD
galaxies show broad distribution in M/L with no detected trend of M/L
with M, the former galaxies having M/L values about twice larger than
the latter, on average. For all the late-type galaxies, the M/L
increases with decreasing effective surface intensity Ie, consistent
with the existence of the Tully-Fisher relation.

Note (3): Characteristic velocity:
central velocity dispersion σ0 or
maximum rotational velocity Vmax according to morphology
Note (4): The effective surface intensity in H-band solar units is
given by Ie = 10exp[-0.4(µe-24.91)]
Note (5): κ coordinates:
-- For elliptical galaxies:
κ1=[log(σ0)2+logre]/sqrt(2)
κ2=[log(σ0)2+2*logIe-logre]/sqrt(6)
κ3=[log(σ0)2-logIe-logre]/sqrt(3)
where re is in kpc, Ie in solar units and σ0 in km/s
-- For spiral and irregular galaxies:
κ1=[log(Vmax)2+logre]/sqrt(2)-0.21
κ2=[log(Vmax)2+2*logIe-logre]/sqrt(6)-0.12
κ3=[log(Vmax)2-logIe-logre]/sqrt(3)-0.17
where Vmax is expresses in km/s
