We present a model for the origin of the extended law of star formation in which the surface density of star formation (Sigma(SFR)) depends not only on the local surface density of the gas (Sigma(g)) but also on the stellar ...

We study the functional form of the star-formation law using the Vaschy–Buckingham Pi theorem. We find that it should have the form Sµ S  ˙ G L gas 3 2, where L is a characteristic length that is related to an integration ...

Aims. We study galaxy pair samples selected from the Sloan Digital Sky Survey (SDSS-DR7) and we perform an analysis of minor and major mergers with the aim of investigating the dependence of galaxy properties on interactions. ...

We investigate the evolution of the galaxy star formation rate function (SFRF) and cosmic star formation rate density (CSFRD) of z ∼ 1–4 galaxies, using cosmological smoothed particle hydrodynamic (SPH) simulations and ...
