We examine the cosmic star formation rate (SFR) and its dependence on galaxy stellar mass over the redshift range 0.8 < z < 2 using data from the Gemini Deep Deep Survey (GDDS). The SFR in the most massive galaxies (M > 10^{10.8} M_sun) was…

We present specific Star Formation Rate (sSFR) radial profiles for a sample of 161 relatively face-on spiral galaxies from the GALEX Atlas of Nearby Galaxies. The sSFR profiles are derived from GALEX & 2MASS (FUV-K) color profiles after a…

Based on the fluxes of 1400 nearby galaxies observed in far ultraviolet (${\rm FUV}$) and in the H$\alpha$ line, we determined the global star formation rate per unit Universe volume, $j_{\rm SFR}=(1.34\pm0.16) 10^{-2}\,M_{\odot}$ yr$^{-1}$…

The Star Formation Rate (SFR) was determined from a sample of 36 late-type galaxies (14 dS and 22 Sm), from the H(alpha) and Far Ultraviolet (FUV) flux. We found that the SFR(FUV) was in most cases higher than the SFR(H(alpha)).We also…

Using a mass-limited sample of 24um-detected, star-forming galaxies at 0.5<z<1.3, we study the mass-star formation rate (SFR) correlation and its tightness. The correlation is well defined (sigma=0.28dex) for disk galaxies (n_sersic<1.5),…

We constrain the mass distribution in nearby, star-forming galaxies with the Star Formation Reference Survey (SFRS), a galaxy sample constructed to be representative of all known combinations of star formation rate (SFR), dust temperature,…

We present the H-alpha flux measurements for 44 nearby dwarf galaxies, derived from the observations at the 6-m BTA telescope. H-alpha fluxes were used to determine the rate of integral star formation of galaxies, SFR. For the observed…
