  1. Determination of Intrinsic Relativistic Velocity Field in M87 Jet ChunCheng Wang (Univ. of Science & Technology of China) Jan. 29-Feb.2, TIARA Winter School

  2. Powerful Large-scale Jet in M87--VLA, HST and Chandra Images

  3. Decades of Puzzle– intrinsic velocity field • Projected proper motion => intrinsic velocity? • Possible origin of supermassive black hole-accretion disk system • Constrain global dynamics even jet formation in vicinity of violent world of central black hole

  4. Synchrotron model fitting to radio-X-ray spectra of M87 Jet (KP & CI)

  5. Determination of intrinsic velocity field • True case– episodic particle acceleration between CI and KP model=>constrain Doppler beaming factor δ • Apparent motion βapp data available in entire jet • Filtering δand βapp in (Γ,θ) parameter space => intrinsic velocity and viewing angle along the jet

  6. Intrinsic velocity field in M87 jet

  7. Further Work • Study possible mechanism of jet deceleration => gas entrainment? • Sample research of large-scale jet’s velocity field • Possible process of episodic particle acceleration=> shock in jet?
