  1. Radio Loud AGN in 2XMMiMulti-wavelength view A. Labiano (ESAC-ESA), M. Guainazzi (ESAC-ESA), S. Bianchi (Rome-3), G. Miniutti (CAB-INTA)

  2. CAIXA • Catalogue of AGN in the XMM-Newton Archive • Veron and XMM 2006/2007 catalogues • Focused on QUIET, un-obscured, targeted AGN observations - 156 sources • 77 QSO, 79 Sy. z = 0.002 – 4.520. Most with z<0.1 • Hard, soft X-ray, Hb, 5GHz, BH mass Bianchi et al. 2009a,b Talk by Ponti

  3. CAIXA - Loud • Goal: Compare properties (and nature) of radio-loud versus radio-quiet AGN • X-corr: 2XMM-DR3, Veron (13th), 2010 catalogues. • Matched ~5000 sources! • Veron gives 1.4, 5 GHz, B and V magnitudes. • X-rays: 0.2-10 kev • Radio data in Veron for ~400 out of the 5000 • Included PKS, TXS, FIRST, NVSS, VLSS, GB6, PMN, WENSS, SUMSS, GB6 – added 100 sources

  4. Radio Loud and Quiet definition • Log R = log f5GHz – log fB • Log RX = log f5GHz – log f2-10KeV • Loud: R > 2.4, Rx> -2.755 Panessa et al. 2007

  5. LOUD QUIET

  6. Optical and radio have same origin (AGN) Host contribution to optical small

  7. Radio loud tend to be x-ray brighter than quiet Optically bright, loud sources are x-ray brighter than optical bright, quiet sources X-rays have higher contribution from??

  8. QUIET LOUD Brightest in radio => brightest in X-ray –> x-ray from jets? Other mechanisms? Why are we missing faint, loud AGN? Obscured? Sample? Sensitivity?

  9. S=0 H=S H=0 HR decreases with optical luminosity -> Obscuring material covers optical and x-rays source Nuclear (BLR, torus) or host-size obscuration?

  10. Two vs. One Powerlaw fits 1 powerlaw 2 powerlaws No evidence of soft excess CAIXA: soft excess in 79% of sources

  11. FeK line example Less than 5% with non-zero flux, with uncertainties ~130% CAIXA: Fe lines in 50% of sources

  12. Spectral Index Quiet -> 1.73 (CAIXA) Type1 -> ~2 (Scott et al. 2011)

  13. Summary • 500 loud AGN with radio, optical and x-rays data. • Where are the faint, loud AGN? Obscured? Sample? Sensitivity? • Small “contamination” from host. • No evidence of soft excess. • Radio loud are brighter in x-rays than radio quiet. • So far, all results point to an extra X-ray component in radio-loud AGN
