2007ApJ...659.1172D Generalizations of the Tully-Fisher Relation for Early- and Late-Type Galaxies Sven De Rijcke, Werner W. Zeilinger, George K. T. Hau, P. Prugniel, and Herwig Dejonghe Abstract. We study the locus of dwarf and giant early- and late-type galaxies on the Tully-Fisher relation (TFR), the stellar mass Tully-Fisher relation (sTFR), and the so-called baryonic or H I gas+stellar mass Tully-Fisher relation (gsTFR). We show that early-type and late-type galaxies, from dwarfs to giants, trace different yet approximately parallel TFRs. Surprisingly, early-type and late-type galaxies trace a single yet curved sTFR over a range of 3.5 orders of magnitude in stellar mass. Moreover, all galaxies trace a single, linear gsTFR, over 3.5 orders of magnitude in H I gas+stellar mass. Dwarf ellipticals, however, lie slightly below the gsTFR. This may indicate that early-type dwarfs, contrary to the late types, have lost their gas, e.g., by galactic winds or ram pressure stripping. Overall, environment only plays a secondary role in shaping these relations, making them a rather "clean" cosmological tool. {LAMBDA}CDM simulations predict roughly the correct slopes for these relations.
