The Star Formation Relation in Nearby Galaxies
I review observational studies of the large-scale star formation process in nearby galaxies. A wealth of new multi-wavelength data provide an unprecedented view on the interplay of the interstellar medium and (young) stellar populations on a few hundred parsec scale in 100+ galaxies of all types. These observations enable us to relate detailed studies of star formation in the Milky Way to the z...
متن کاملStar Formation Histories of Nearby Dwarf Galaxies
Properties of nearby dwarf galaxies are briefly discussed. Dwarf galaxies vary widely in their star formation histories, the ages of their subpopulations, and in their enrichment history. Furthermore, many dwarf galaxies show evidence for spatial variations in their star formation history; often in the form of very extended old populations and radial gradients in age and metallicity. Determinin...
متن کاملThe evolution of the star formation rate function and cosmic star formation rate density of galaxies at z ̃ 1-4
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...
متن کاملStar Formation in the Milky Way and Nearby Galaxies
We review progress over the past decade in observations of large-scale star formation, with a focus on the interface between extragalactic and Galactic studies. Methods of measuring gas contents and star formation rates are discussed, and updated prescriptions for calculating star formation rates are provided. We review relations between star formation and gas on scales ranging from entire gala...
متن کاملThe Star Formation Rate-Dense Gas Relation in the Nuclei of Nearby Galaxies
We investigate the relationship between the star formation rate (SFR) and dense molecular gas mass in the nuclei of galaxies. To do this, we utilize the observed 850 mm luminosity as a proxy for the infrared luminosity ( ) and SFR, and we correlate this with the observed CO( ) luminosity. We find tentative evidence that L J p 3–2 IR the -CO( ) index is similar to the Kennicutt-Schmidt (KS) inde...
