Calibration of the Tully-Fisher relation in the field

Stéphane Rauzy

Résumé

A new technique for calibrating Tully-Fisher like relations by using field galaxies is proposed. Based on a null-correlation approach (NCA), the technique is insensitive to the presence of selection effects on apparent magnitude $m$ and on log line-width distance indicator p. This interesting property is used for discarding near by galaxies of the observed sample. It is shown that such a subsampling allows in effect to attenuate biases on calibration parameters created by the presence of radial peculiar velocities.
