Abstract:
In order to explore local large-scale structures and velocity fields,
accurate galaxy distance measures are needed. We now extend the
well-tested recipe for calibrating the correlation between galaxy
rotation rates and luminosities-capable of providing such distance
measures-to the all-sky, space-based imaging data from the Wide-field
Infrared Survey Explorer (WISE) W1 (3.4 µm) and W2 (4.6 µm)
filters. We find a correlation of line width to absolute magnitude
(known as the Tully-Fisher relation, TFR) of
MW1b,i,k,a=-20.35-9.56(logWmxi-2.5) (0.54 mag rms) and
MW2b,i,k,a=-19.76-9.74(logWmxi-2.5) (0.56 mag rms) from 310
galaxies in 13 clusters. We update the I-band TFR using a sample 9%
larger than in Tully & Courtois (2012ApJ...749...78T 2012ApJ...749...78T). We derive
Mlb,i,k=-21.34-8.95(logWmxi-2.5) (0.46 mag rms). The WISE TFRs
show evidence of curvature. Quadratic fits give
MW1b,i,k,a=-20.48-8.36(logWmxi-2.5)+3.60(loglogWmxi-2.5)2
(0.52 mag rms) and MW2b,i,k,a=-19.91-8.40(logWmxi-2.5)+
4.32(loglogWmxi -2.5)2 (0.55 mag rms). We apply an I-band -WISE
color correction to lower the scatter and derive
MCw1=-20.22-9.12(logWmxi-2.5) and MCw2=-19.63-9.11(logWmxi-2.5)
(both 0.46 mag rms). Using our three independent TFRs (W1 curved,
W2 curved, and I band), we calibrate the UNION2 Type Ia supernova
sample distance scale and derive H0=74.4±1.4(stat)±2.4(sys) km/s/Mpc
with 4% total error.
Description:
We have instigated a separate project to provide high-quality surface
photometry of all WISE galaxies larger than 0.8' on the sky. The
WISE Nearby Galaxy Atlas (WNGA; M. Seibert et al., in preparation)
will provide photometry that is quality controlled for over 20000
galaxies. This photometry, optimized for extended sources,
significantly reduces the resulting scatter in the Tully-Fisher
relation (here after TFR) calibration and thus improves the resulting
distances. Having an accurate calibration of the TFR for these two
WISE passbands will allow the use of this large sample to explore the
structure and dynamics of local galaxy bulk flows. With the current
tally, there are 310 cluster calibrators with WISE W1 and W2
photometry, compared with 213 available to Sorce et al.
(2013, J/ApJ/765/94) for the Spitzer calibration, and 291 of the 310
WISE calibrators have I-band photometry, compared with the 267
available to Tully & Courtois (2012ApJ...749...78T 2012ApJ...749...78T) for the previous I-band
calibration.
