Presentation Transcript

  1. Local interstellar emission • 100 MeV – 1 GeV, 6 days, 0.2°x0.2° • 5° ≤ |b| ≤ 30°

  2. CO maps

  3. HI maps

  4. GLAST 0.1-1 GeV

  5. interstellar fit with all sources • qHI = (2.59 ± 0.03) 10-26 at-1 sr-1(high)asuming 7300 cm² • qH2 = (4.6 ± 0.3) 10-6 sr-1cm-2 K-1 km-1 • Ibkg = (1.94 ± 0.03) 10-5 cm-2 s-1 sr-1 • X = (0.9 ± 0.1) 1020mol. cm-2 K-1 km-1 s

  6. interstellar fit removing sources • qHI = (2.52 ± 0.03) 10-26 at-1 sr-1asuming 7300 cm² • qH2 = (4.6 ± 0.3) 10-6 sr-1cm-2 K-1 km-1 • Ibkg = (1.91 ± 0.03) 10-5 cm-2 s-1 sr-1 • X = (0.9 ± 0.1) 1020mol. cm-2 K-1 km-1 s • source bias << • not true at |b|<5° ! • IC or exotic halo?

  7. source profiles • gaussian fits to longitude and latitude profiles

  8. source profiles
