description
SDSS spectra were used with the Hubble law to create a map. This is an AGN Spectral Energy Distribution (SED). We are picking quasars since they outshine their host galaxy. Color. But redshift as well as temperature affects the color of a galaxy?. Resdshift : 1+z= l o/ l e. 8. - PowerPoint PPT Presentation

Where shall we get our AGN?
• “The UV Properties of SDSS-Selected Quasars” by Trammel et al., 2007 (AJ, 133, 1780) provides the UV data
• There are 479 sources between at 0.1 < z < 0.5
• All the sources are in the WISE survey provides the IR data
