The Star Formation Rate Intensity Distribution Function—implications for the Cosmic Star Formation Rate History of the Universe
We address the effects of cosmological surface brightness dimming on observations of faint galaxies by examining the distribution of “unobscured” star formation rate intensities versus redshift. We use the star formation rate intensity distribution function to assess the ultraviolet luminosity density versus redshift, based on our photometry and photometric redshift measurements of faint galaxi...
متن کاملThe Star Formation Rate Intensity Distribution Function — Comparison of Observations with Hierarchical Galaxy Formation
Recently, Lanzetta et al. (2002) have measured the distribution of star formation rate intensity in galaxies at various redshifts. This data set has a number of advantages relative to galaxy luminosity functions; the effect of surface-brightness dimming on the selection function is simpler to understand, and this data set also probes the size distribution of galactic disks. We predict this func...
متن کاملMatching the Observed Star Formation Intensity Distribution with Empirical Laws
This letter matches the shape of the star formation intensity distribution function to empirical laws such as the Schmidt law. The shape of the distribution at a redshift of one is reproduced from the empirical Schmidt law with a critical density, a Schechter distribution of galaxy masses and the assumption that star formation occurs mainly in exponential disks. The shape of the distribution de...
متن کاملThe evolution of the star formation rate function and cosmic star formation rate density of galaxies at z ̃
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 a compilation of ultraviolet (UV), infrared (IR) and Hα observations. These tracers represent different populations of galaxies with the IR light being a probe of objects with hi...
