Abstract:
Distance measures on a coherent scale around the sky are required to
address the outstanding cosmological problems of the Hubble constant
and of departures from the mean cosmic flow. The correlation between
galaxy luminosities and rotation rates can be used to determine the
distances to many thousands of galaxies in a wide range of
environments potentially out to 200Mpc. Mid-infrared (3.6µm)
photometry with the Spitzer Space Telescope is particularly valuable
as a source of luminosities because it provides products of uniform
quality across the sky. From a perch above the atmosphere, essentially
the total magnitude of targets can be registered in exposures of a few
minutes. Extinction is minimal and the flux is dominated by the light
from old stars, which is expected to correlate with the mass of the
targets. In spite of the superior photometry, the correlation between
mid-infrared luminosities and rotation rates extracted from neutral
hydrogen profiles is slightly degraded from the correlation found with
I-band luminosities. A color correction recovers a correlation that
provides comparable accuracy to that available at the I band (∼20%
1σ in an individual distance) while retaining the advantages
identified above. Without color correction, the relation between
linewidth and [3.6] magnitudes is
Mb,i,k,a[3.6]=-20.34-9.74(logWimx-2.5). This description is
found with a sample of 213 galaxies in 13 clusters that define the
slope and 26 galaxies with Cepheid or tip of the red giant branch
distances that define the zero point. A color-corrected parameter
Mc[3.6] is constructed that has reduced scatter:
Mc[3.6]=-20.34-9.13(logWmxi-2.5). Consideration of the seven
calibration clusters beyond 50Mpc, outside the domain of obvious
peculiar velocities, provides a preliminary Hubble constant estimate
of H0=74±4km/s.M/pc.
Description:
The slope and zero-point calibrator samples are described in detail in
Tully & Courtois, 2012ApJ...749...78T 2012ApJ...749...78T. The correlation slope is
established from a template built from galaxies in 13 clusters.
The photometric data have all been obtained with Spitzer/IRAC ch.1,
passband center 3.55um. The Carnegie Hubble Program (CHP; Freedman et
al. 2011AJ....142..192F 2011AJ....142..192F) provides 60% of the data. In addition, S4G,
the Spitzer Survey of Stellar Structure in Galaxies (Sheth et al.
2010, Cat. J/PASP/122/1397), gives 17%, and SINGS, the Spitzer
Infrared Nearby Galaxies Survey (Dale et al. 2005ApJ...633..857D 2005ApJ...633..857D,
2007ApJ...655..863D 2007ApJ...655..863D), gives 9%. The new Cosmic Flows with Spitzer
(CFS) program has only contributed 3% of the current data. Smaller
programs during the cryogenic mission supply us with information on
the remaining galaxies.
