| Abstract | |
We present results on the Tully-Fisher relation of galaxies in dense environments as compared to galaxies in the field. Our main result is that galaxies in Hickson compact groups (HCG) lie on the K-band Tully-Fisher relation defined by galaxies in less dense environments (GHASP survey) although with more scatter. However, some of the lowest mass systems (e.g. 49b) have a mass that is too low for their stellar luminosities. These galaxies could have their dark halos truncated due to interactions. (AU) | |
