The Tully – Fisher Relation and H ◦
The use of the Tully–Fisher (TF) relation for the determination of H◦ relies on the availability of an adequate template TF relation and of reliable primary distances. Here we use a TF template relation with the best available kinematical zero–point, obtained from a sample of 24 clusters of galaxies extending to cz ∼ 9, 000 km s , and the most recent set of Cepheid distances for galaxies fit fo...
متن کاملCalibration of the Tully-Fisher relation in the field
A new technique for calibrating slope and relative zero-point of Tully-Fisher like relations by using a sample of distant 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 nearby galaxies of t...

Surface Photometric Calibration of the Infrared Tully-Fisher Relation Using Cepheid-based Distances of Galaxies
Infrared J and H surface photometry are carried out for nearby 12 galaxies whose distances have been accurately measured via HST Cepheid observations. Using the total, isophotal, and surface-photometric aperture magnitudes we calibrate the infrared luminosity-line width relation (IRTF). It is found that IRTF changes its slope at log W c 20 ∼ 2.45 in all the examined magnitude systems. The appar...
متن کاملThe Baryonic Tully-Fisher Relation.
We explore the Tully-Fisher relation over five decades in stellar mass in galaxies with circular velocities ranging over 30 less, similarVc less, similar300 km s-1. We find a clear break in the optical Tully-Fisher relation: field galaxies with Vc less, similar90 km s-1 fall below the relation defined by brighter galaxies. These faint galaxies, however, are very rich in gas; adding in the gas m...
