The SAMI Galaxy Survey: The low-redshift stellar mass Tully-Fisher relation
We investigate the Tully-Fisher relation (TFR) for a morphologically and kinematically diverse sample of galaxies from the Sydney-AAO Multi-object Integral field spectrograph (SAMI) Galaxy Survey using two-dimensional spatially resolved Ha velocity maps and find a well-defined relation across the st...

We investigate the Tully-Fisher relation (TFR) for a morphologically and kinematically diverse sample of galaxies from the Sydney-AAO Multi-object Integral field spectrograph (SAMI) Galaxy Survey using two-dimensional spatially resolved Ha velocity maps and find a well-defined relation across the stellar mass range of 8.0 < log (M*/M-circle dot) < 11.5. We use an adaptation of kinemetry to parametrize the kinematic Ha asymmetry of all galaxies in the sample, and find a correlation between scatter (i.e. residuals off the TFR) and asymmetry. This effect is pronounced at low stellar mass, corresponding to the inverse relationship between stellar mass and kinematic asymmetry found in previous work. For galaxies with log (M*/M-circle dot) < 9.5, 25 +/- 3 per cent are scattered below the root mean square (RMS) of the TFR, whereas for galaxies with log (M*/M-circle dot) > 9.5 the fraction is 10 +/- 1 per cent.
