Hα star formation rates for a sample of star-forming galaxies from SDSS (DR1)
A study of current star formation rates (SFRs) derived from Hα emission of ionized hydrogen for 1305 star-forming galaxies from the Sloan Digital Sky Survey (Data Release 1) is carried out. Current SFRs are derived from the Hα flux corrected for interstellar extinction and aperture. For a subsample...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Zusammenfassung: | A study of current star formation rates (SFRs) derived from Hα emission of ionized hydrogen for 1305 star-forming galaxies from the Sloan Digital Sky Survey (Data Release 1) is carried out. Current SFRs are derived from the Hα flux corrected for interstellar extinction and aperture. For a subsample of 45 galaxies the current SFRs are derived using simultaneously three parameters: the galaxy luminosity in the far infrared range (IRAS data), the monochromatic radio continuum luminosity at 1.4 GHz (NVSS data), and the Hα emission of ionized hydrogen (SDSS DR1 data). The results obtained are discussed and compared with the similar ones for the Markarian galaxies. |
