The Tully-Fisher (TF) relation is an empirically establish correlation between the luminosity of spiral galaxy and its rotational velocity (Tully-Fisher, 1977). We used the Tully-Fisher relation in order to probe the dark matter (DM) distribution in the optical regions of spiral galaxies. We investigated a sample of rotation curves that includes 957 galaxies. The new technique applied takes advantages on the full knowledge of the galaxy rotation curves.

Abstract
The Tully-Fisher (TF) relation is an empirically establish correlation between the luminosity of spiral galaxy and its rotational velocity (Tully-Fisher, 1977). We used the Tully-Fisher relation in order to probe the dark matter (DM) distribution in the optical regions of spiral galaxies. We investigated a sample of rotation curves that includes 957 galaxies. The new technique applied takes advantages on the full knowledge of the galaxy rotation curves.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
