1 X-Ray Observations of SN1006 Koyama, K. Kyoto University Palmieri et al (1972) Ballon : The first X-ray detection Winkler and Laird : OSO7 The spectrum Photon index =2.3 or kT = 4 keV Becker et al (1980) SSS, OSO8 : Crab Like spectrum : Photon index = 2.2 (no line) Vartanian et al.1985 (GSPC: Balloon) Detection of OVII line = Thermal Plasma (0,1-0.2 keV) Koyama et al. 1987 (GSPC: Tenma) : Steeper Power law Photon index- 3.3 NEI Plasma kT 1.9 keV Morphology Chandra: Very Thin Filaments Spectroscopy Suzaku Thermal vs Non-Thermal

2 Chandra: Thin Filaments (Bamba et al.) In this region, electron returns back (small: quick, large: slow) The thin filaments = diffusion to the shock normal is small The Efficiency of Particle Acceleration NR: High ER: Low A ping-pong ball gets speed (energy) by a rally in a moving wall shock

3 B (perpendicular) down stream becomes very turbulent, hence be strongly scattered. B=100 – 400  G (Berezhko et al. 2004) B (pararell) Strong B makes the gyro radius small → diffusion becomes small Efficient particle accelerations  Thermal plasma shock E= 50-80 TeV. B=10 – 20  G up down

4 E0102-72 Suzaku: Launch:2005/7/10 XIS Suzaku XIS-FI Suzaku XIS-BI O VII O VIII Ne IX Ne X BI: Good Response at low energy FI: Low and Stable BG at high energy Galactic Center

5 Black : XIS-BI Red : average of 3 XIS-FIs He-O H-O Non-thermal emission 3 - 5 keV band 3-5 keVOVII band See also Poster E1.4-0025-06

6 North rim East rim Inner We divide the NE rim region into 64 segments. Made each spectra Fit with a Power-law + thin plasma model Then.

7 Assuming CIE Plasma kT = constant He-O line is prportinal to the thin thermal flux. North rim East rim Inner region Large Thermal Flux Steep Non Thermal North rim East rim Inner

8 Results of the CIE Case (1) Stronger OVII Flux (Thermal flux) Region has a steeper gamma (Non Thermal) (2) 3 regions (NR, ER, Inner) are separated by the Hard X-ray Flux vs OVII flux map Chandra Image North Rim East Rim This is CIE case However the plasma in a young SNR Is likely NIE. We then try NIE plasma

9 Hard to distinguish CIE vs NEI Two Local Minima at large nt and small nt

10 Gamma-map kT-map nt-map NEI Results Support Smaller Larger Lower Larger Higher Smaller

11 Conclusion North Rim Low density High temp and Highly NEI better injector to the accelerator. Flat Γ, Sharp W u  Acceleration efficiency is high  Total thermal energy of plasma becomes small East Rim High density Low temp and Moderate NEI Steep Γ, Slow W u  Acceleration efficiency is low  Total thermal energy of plasma remains large Chandra Image North Rim East Rim

12 Japanese historical record of SN1006 “Meigetsuki” (This page was written in 8 th September, in 1230.) 「客星古現例」 the ancient samples of “guest stars”. Guest stars = comets, novae, or supernovae SN1006

13 ToJi Temple Teika Suzaku-Mon Gate Palace SaiJi Temple Suzaku Av. Rajyo-Mon Gate

14 Southern Sky from Kyoto in AD1006/05/01 Mars Antares SN1006 Sai-Ji To- Ji

15 ToJi Temple Tomb of Teika Koyama House of Teika

16 朱雀 Suzaku The wall painting of “Suzaku” i n the ancient tomb “Kitora” built in the Asuka Era Since the dead line of paper submission is approaching, please visit here http://www-cr.scphys.kyoto-u.ac.jp/ conference/suzaku2006/conference/suzaku2006/registration/registration.cgi and go into proper action
