  1. I. Correlation among RM, HI, FF, & Synch. Emissions Y. Sofue 2014.8.8 @SKA_mag_meeting

  2. 1. DATA

  3. All-sky RM, HI, FF, Synch (l, b) Tables by: H. Nakanishi H. Ichiki Data from: Taylor, et al. 2009 Kalbella et al. 2008 Gold et al. 2012 WMAP7

  4. RMSky (Taylor 2009) HI sky (Kalbella et al. 2011

  5. Synchrotron & Free-Free emissions (WMAP 7, Gold et al. 2012)

  6. WMAP B vectors: (Jansson et al. 2012)

  7. Map(radio) – Map(HI, etc) • 408 MHz – HI total = not uniform: • Not frozen-in, at least some regions.

  8. 2. B-Frozen-in / Energy Equipartition, or else?

  9. If ISM energy equipartition:ne~nHI~NCR~B2RM~neB//L ~nHI3/2L HI~nHIL FF~ne2 L~nHI2 L Synch~NCRB2 L~B4 L~nHI2 L

  10. If B frozen in ISM (ne , nHI): • B ~ ρ2/3 ~ne/HI2/3 • (B-CR Eq.par.=>B2 ~Ncr) • Synch. ~ B2 Ncr L ~ B4 L~ nHI8/3 L

  11. Log I(radio) - Log N(HI,H2,dust) plot.

  12. 2. Global Correlation

  13. 3. RM vs HI Ordered B / Turbulent B, • Local B reversals

  14. RM vs Gas (HI, H2, HII, COBE) plot

  15. 4. RM, HI, FF, Syn vs Latitude

  16. 5. Window for Cosmology

  17. II.Galactic Variation of RM

  18. Data: Taylor, et al. 2009 Kalbella et al. 2011 Tables H. Nakanishi

  19. 1. RM vs Longitude

  20. 2. RM vs Latitude

  21. 3. Local B G-Plane Reversal
