Starburst and AGN activity in ultraluminous infrared galaxies
Starburst and AGN activity in ultraluminous infrared galaxies
We examine the power source of 41 local ultraluminous infrared galaxies (ULIRGs) using archival infrared (IR) and optical photometry. We fit the observed spectral energy distributions with starburst and active galactic nucleus (AGN) components, each component being drawn from a family of templates. We find that all of the sample …
