CHANDRA HANDRA (and XMM-Newton) XMM XMM-Newton) ewton) View iew of AGNs AGN AGNs • Black Hole finding machines: x-rays pass through gas and dust - Brandt & Hasinger, Barger et al, Silverman et al, & others • AGN sky density ~ 7000 per sq deg for CDFs • Faint x-ray sources diverse - BLAGN, NELG, ALG • No longer simply Type 1 = broad lines, blue colors, & unobscured Type 2 = narrow lines, red colors, & obscured - Some BLAGN show x-ray absorption - Some NELG and red BLAGN (2MASS) not absorbed - Optically dull galaxies (Elvis 1981) reincarnated as XBONGs, with no hint from opt lines & colors. L x as high as 10 44 - More absorbed objects (10 23 -10 24 ) detectable above 5 keV? CHANDRA
CHANDRA HANDRA (and XMM-Newton) XMM XMM-Newton) ewton) View iew of AGNs AGN AGNs • SMBH grow in "anti-hierarchical" way Most massive (10 7 .5 - 10 9 M o ) form early and feed often - More frequent mergers and more gas available at high z - High luminosity, BLAGN, & numbers peak at z ~2.5 More moderate (10 6 -10 7 .5 M o ) form later and grow more slowly - Less luminous (~100x) & numbers peak at z ~1 • Relevant factors History of host galaxy, growth of SMBH, & gas supply (In)efficiency of radiation processes – impact on M BH from L x Roles of jets as well as accretion disk Presence of obscuring torus and viewing geometry CHANDRA
