Description
Galaxies obey scaling relations between global physical properties like stellar mass-size, mass-star formation rate, and mass-gas metallicity. Exploiting kinematics as proxy for total mass relations between the baryonic components and the dark matter can be explored like the Tully-Fisher or Fundamental Plane relations. Such scaling relations allow to measure galaxy evolution across cosmic epochs in a quantitative way. In addition, they serve as benchmarks to verify predictions from simulations.
