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

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, H , 5GHz, BH mass Bianchi et al. 2009a,b Talk by Ponti

CAIXA - Loud Goal: Compare properties (and nature) of radio- loud versus radio-quiet AGN X-corr: 2XMM-DR3, Veron (13 th ), 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

CAIXA - Loud Goal: Compare properties 8and nature) of quiet/loud AGN Similar study, for radio-LOUD AGN 2XMM-DR3, Veron (13 th ), 2010 catalogues. ~5000 matched sources. Veron gives 1.4, 5 GHz, B and V magnitudes. X-rays: 0.2-10 kev Radio data for ~400 Included PKS, TXS, FIRST, NVSS, VLSS, GB6, PMN, WENSS, SUMSS, GB6 – 100 sources. IR catalogue? IRAS -> 10 sources

Radio Loud and Quiet definition Log R = log f 5GHz – log f B Log RX = log f 5GHz – log f 2-10KeV Loud: R > 2.4, Rx> -2.755 Panessa et al. 2007
6
Loud / Quiet Log R = log f 5GHz – log f B Log RX = log f 5GHz – log f 2-10KeV Loud: R > 2.4, Rx> -2.755 R -> 300 Quiet, 103 Loud. Rx -> 176 Quiet, 227 Loud. Panessa et al. 2007

LOUD QUIET
8
Optical and radio have same origin (AGN) Host contribution to optical small
10
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??
12
Brightest in radio => brightest in X-ray –> x-ray from jets? Other mechanisms? Why are we missing faint, loud AGN? Obscured? Sample? Sensitivity? LOUD QUIET
13
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?
16
Two vs. One Powerlaw fits 2 powerlaws 1 powerlaw No evidence of soft excess CAIXA: soft excess in 79% of sources
17
Less than 5% with non-zero flux, with uncertainties ~130% FeK line example CAIXA: Fe lines in 50% of sources
18
Spectral Index Quiet -> 1.73 (CAIXA) Type1 -> ~2 (Scott et al. 2011)
19
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
