Applications of the Tully-Fisher Relation at High Redshift
We discuss the possibilities of using the velocity width integrated luminosity relation for spiral galaxies at cosmologically interesting redshifts. Our estimates and discussion show that questions of cosmological nature can be usefully addressed by use of optical lines such as Hα, when observed as integrated profiles on a 16-m ground-based telescope such as ESO’s VLT.
