Abstract:
We present the final distance measurements for the 2MASS
Tully-Fisher (2MTF) survey. The final 2MTF catalogue contains 2062
nearby spiral galaxies in the CMB frame velocity range of
600<cz<10000km/s with a mean velocity of 4805km/s. The main update in
this release is the replacement of some archival HI data with newer
ALFALFA data. Using the 2MTF template relation, we calculate the
distances and peculiar velocities of all 2MTF galaxies. The mean
uncertainties of the linear distance measurements are around 22 per
cent in all three infrared bands. 2MTF measurements agree well with
the distances from the Cosmicflows-3 compilation, which contains 1117
common galaxies, including 28 with SNIa distance measurements. Using
distances estimated from the '3-bands combined' 2MTF sample and a
χ2 minimization method, we find best-fitting bulk flow
amplitudes of 308±26km/s, 318±29km/s, and 286±25km/s at depths
of RI=20, 30 and 40h-1Mpc, respectively, which is consistent
with the {LAMNDA}CDM model and with previous 2MTF results with
different estimation techniques and a preliminary catalogue.
Description:
2MTF survey provides Tully-Fisher distances and peculiar velocities to
2062 nearby spiral galaxies.
Table 1 present the photometric data from 2MRS catalogue and corrected
HI widths for the 2062 2MTF galaxies. Table 2 contains the logarithmic
distance quantity measured by 2MTF, together with linear peculiar
velocities, the peculiar velocities generated from the estimator
introduced by Watkins & Feldman (2015MNRAS.450.1868W 2015MNRAS.450.1868W) are included in
Table 2.
