Abstract:
We combine data from the Spitzer Survey for Stellar Structure in
Galaxies, a recently calibrated empirical stellar mass estimator from
Eskew et al., and an extensive database of HI spectral line profiles
to examine the baryonic Tully-Fisher (BTF) relation. We find (1) that
the BTF has lower scatter than the classic Tully-Fisher (TF) relation
and is better described as a linear relationship, confirming similar
previous results, (2) that the inclusion of a radial scale in the BTF
decreases the scatter but only modestly, as seen previously for the TF
relation, and (3) that the slope of the BTF, which we find to be
3.5±0.2(ΔlogMbaryon/Δlogvc), implies that on average
a nearly constant fraction (∼0.4) of all baryons expected to be in a
halo are "condensed" onto the central region of rotationally supported
galaxies. The condensed baryon fraction, Mbaryon/Mtotal, is, to
our measurement precision, nearly independent of galaxy circular
velocity (our sample spans circular velocities, v c, between 60 and
250km/s, but is extended to vc∼10km/s using data from the
literature). The observed galaxy-to-galaxy scatter in this fraction is
generally ≤ a factor of 2 despite fairly liberal selection
criteria. These results imply that cooling and heating processes, such
as cold versus hot accretion, mass loss due to stellar winds, and
active galactic nucleus driven feedback, to the degree that they
affect the global galactic properties involved in the BTF, are
independent of halo mass for galaxies with 10<vc<250km/s and
typically introduce no more than a factor of two range in the
resulting Mbaryon/Mtotal. Recent simulations by Aumer et al. of a
small sample of disk galaxies are in excellent agreement with our
data, suggesting that current simulations are capable of reproducing
the global properties of individual disk galaxies. More detailed
comparison to models using the BTF holds great promise, but awaits
improved determinations of the stellar masses.
Description:
The photometric data, from which we obtain the measurements of the
infrared luminosity, half light radii, and inclinations come from the
S4G data set (Sheth et al., 2010, cat. J/PASP/122/1397) and
subsequent analysis described by J.-C. Munoz-Mateos et al. (2013, in
preparation) and H. Salo et al. (2014, in preparation). The basic data
consist of images obtained with the Spitzer Space Telescope with the
IRAC instrument during its warm mission, so limited to the 3.6µm
and 4.5µm channels, of 2352 galaxies in the local universe.
We currently have coherent HI measurements for 16121 galaxies. Of
those, 12189 are of sufficient quality for distance measurements with
Tully-Fisher. This catalog is available for public use at the
Extragalactic Distance Database Web site (http://edd.ifa.hawaii.edu/ )
and we call it the "All Digital HI catalog."

Note (1): Corrected for inclination.
Note (2): HI mass corrected for He and metals.
Note (3): Estimated as described in Section 3.2.
Note (4): We consider that the standard Tully-Fisher relation does not describe
early-type galaxies, which can have stellar components with almost no
rotation that are quite luminous. To eliminate these galaxies, we consider
only galaxies of T-type>1.5 (Sab's and later).
