LOW-RESOLUTION SPECTRAL TEMPLATES FOR ACTIVE GALACTIC NUCLEI AND GALAXIES FROM 0.03 TO 30 μm

摘要: We present a set of low-resolution empirical spectral energy distribution (SED) templates for active galactic nuclei (AGNs) and galaxies in the wavelength range from 0.03 ?m to 30 based on multi-wavelength photometric observations NOAO Deep-Wide Field Survey Bo?tes field spectroscopic AGN Galaxy Evolution Survey. Our training sample is comprised 14,448 redshift 0 z 1 5347 likely AGNs 5.58. The galaxy correspond SED presented 2008 by Assef et al. extended into UV mid-IR addition FUV NUV GALEX MIPS 24 data field. use our determine redshifts AGNs. While they are relatively accurate (? /(1 + z) = 0.04, with 5% outlier rejection), their accuracies strong function luminosity ratio between components. Somewhat surprisingly, relative luminosities its host well determined even when significantly error. also study selection criteria developed Stern 2005 Lacy 2004. find that criterion suffers significant incompleteness there component at 4.5, broad H? emission line redshifted [3.6] band, but it little contaminated low- intermediate-redshift galaxies. not affected 4.5 somewhat less components, heavily low-redshift star-forming Finally, we predict color-color sources upcoming Wide-Field Infrared Explorer (WISE) mission define color select analogous those IRAC photometry. estimate 640,000 1,700,000 will be identified these criteria, without additional information, WISE-selected quasars have serious completeness problems 3.4.
