Spatially Resolved Kinematics of Distant Galaxies

Abstract

A Tully-Fisher (TF) relation from Hα rotation curves of 19 luminous, star-forming galaxies reveals there is little evidence for evolution in the mass-to-light ratio (M/L) of these galaxies to z ∼ 0.3. The nearinfrared Tolman surface-brightness test for other luminous galaxies indicates their luminosity also is little changed to z ∼ 0.3. In this redshift… (More)
