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?
