2013ApJ...771...88L WISE TF: A Mid-infrared, 3.4 micron Extension of the Tully-Fisher Relation Using WISE Photometry Lagattuta, David J.; Mould, Jeremy R.; Staveley-Smith, Lister; Hong, Tao; Springob, Christopher M.; Masters, Karen L.; Koribalski, Barbel S.; Jones, D. Heath Abstract. We present a mid-infrared Tully-Fisher (TF) relation using photometry from the 3.4 micron W1 band of the Wide-field Infrared Survey Explorer (WISE) satellite. The WISE TF relation is formed from 568 galaxies taken from the all-sky 2MASS Tully-Fisher (2MTF) galaxy catalog, spanning a range of environments including field, group, and cluster galaxies. This constitutes the largest mid-infrared TF relation constructed to date. After applying a number of corrections to galaxy magnitudes and line widths, we measure a master TF relation given by M_corr_ = --22.24 -- 10.05[log (W_corr_) -- 2.5], with an average dispersion of sigma_WISE_ = 0.686 mag. There is some tension between WISE TF and a preliminary 3.6 micron relation, which has a shallower slope and almost no intrinsic dispersion. However, our results agree well with a more recent relation constructed from a large sample of cluster galaxies. We additionally compare WISE TF to the near-infrared 2MTF template relations, finding a good agreement between the TF parameters and total dispersions of WISE TF and the 2MTF K-band template. This fact, coupled with typical galaxy colors of (K -- W1) ~ 0, suggests that these two bands are tracing similar stellar populations, including the older, centrally-located stars in the galactic bulge which can (for galaxies with a prominent bulge) dominate the light profile. Key words: distance scale, galaxies: fundamental parameters, galaxies: spiral, infrared: galaxies
