Presentation Transcript

  1. Radio Loud Quasars and GLAST Aneta Siemiginowska Harvard-Smithsonian Center for Astrophysics

  2. Opt-UV LBL HBL LBL FSQR HBL Compton SYN Blazar Sequence: FSRQ ? Donato et al 2000 Aneta Siemiginowska

  3. 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? Aneta Siemiginowska

  4. Multi-wavelength DATA: PKS1127-145 z=1.187 X-rays: Beppo SAX - 1999 Chandra - 2000/2005 XMM - 2002 Swift - 2007 (140ksec) EGRET(?) - 1993/1995 Aneta Siemiginowska

  5. MODELS: SSC model fit to the radio and BeppoSAX data Giommi et al 2002 SSC Aneta Siemiginowska

  6. Inverse Compton on an External Photon Field - Sikora Model 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 • LAT energy Band: • Critical for this Model • Jet vs. Corona-Disk contribution to the X-ray band Blazejowski et al 2004 Aneta Siemiginowska
