The importance of nebular emission for SED modeling of distant star-forming galaxies

Schaerer, Daniel, de Barros, Stephane

Understand

We highlight and discuss the importance of accounting for nebular emission in the SEDs of high redshift galaxies, as lines and continuum emission can contribute significantly or subtly to broad-band photometry.

  • Physical parameters such as the galaxy age, mass, star-formation rate, dust attenuation and others inferred from SED fits can be affected to different extent by the treatment of nebular emission.
  • We analyse a large sample of Lyman break galaxies from z~3-6, and show some main results illustrating e.g.
  • the importance of nebular emission for determinations of the mass-SFR relation, attenuation and age.
