On the Star Formation-AGN Connection at $z \lesssim 0.3$

Understand

Using the spectra of a sample of $\sim$28,000 nearby obscured active galaxies from Data Release 7 of the Sloan Digital Sky Survey (SDSS), we probe the connection between AGN activity and star formation over a range of radial scales in the host galaxy.

• We use the extinction-corrected luminosity of the [OIII] 5007 \AA\ line as a proxy of intrinsic AGN power and supermassive black hole (SMBH) accretion rate.
• The star formation rates (SFRs) are taken from the MPA-JHU value-added catalog and are measured through the 3$^{\prime\prime}$ SDSS aperture.
• We construct matched samples of galaxies covering a range in redshifts.
