GLAST WorkshopAneta Siemiginowska Blazar Sequence: FSRQ ? Opt-UV LBL HBL SYN Compton FSQR HBLLBL Donato et al 2000

GLAST WorkshopAneta Siemiginowska X-rays vs. Gamma-ray Emission Unified picture:  What process dominates X-ray emission? Jet vs. Corona  FSRQ - optical/UV lines => Can determine the BH mass  UV emission - an accretion state?

GLAST WorkshopAneta Siemiginowska Multi-wavelength DATA: PKS z=1.187 X-rays: Beppo SAX Chandra /2005 XMM Swift (140ksec) EGRET(?) /1995

GLAST WorkshopAneta Siemiginowska MODELS: SSC model fit to the radio and BeppoSAX data SSC Giommi et al 2002

GLAST WorkshopAneta Siemiginowska Model Components: SYN - synchrotron SSC - Compton scattering of SYN ERC(IR) - IC/IR field due to dust ERC(UV) - IC/UV field from AD ERC(BEL) - IC/BEL Clouds Inverse Compton on an External Photon Field - Sikora Model Blazejowski et al 2004 LAT energy Band: - Critical for this Model - Jet vs. Corona-Disk contribution to the X-ray band
