  1. Evidence for shocked Molecular Gas in the Galactic SNR CTB 109 Astro-ph/ 0604164 Manami Sasaki, Roland Kothes et al.

  2. CTB 109 (G109.1-1.0) 1. Incomplete Shell + Long Period X-ray Pulsar; 2. R ~ 14 arcmin; 3. D (HII) ~ 3 kpc; 4. Flux (1 GHz) ~ 20 Jy; Index ~ 0.5; 5. The Molecular cloud S152 in the west;

  3. The anti-correlation of the CO emission with the X-ray emission; • 12CO (optically thick) / 13CO (optically thin); • X-ray fitting  N(H)  foreground CO fitting  N(H2)

  4. CO arm  a systematic velocity of –51 km/s

  5. Seoul Radio Astronomy Observatory (SRAO) https://srao.snu.ac.kr Antenna Diameter: 6m Frequency: 85 – 115 GHz (0-120 Km/s) Pointing Error: < 10” Tracking Accuracy: < 0.4” Maximum Bandwidth: 100MHz & 50 MHz

  6. Observe: 1. Standard Source (position switch); 2. Reference Position (frequency swith); 3. Mapping; Analysis: 1.Gildas (class)  baseline subtracted; 2. Sum  rpfits files; 3. Miriad  multi-wavelength;

  7. RMS=T(system)/Sqrt(f*t); T(system) ~ 500-700 K f = 50 MHz/1024; v=120 km/s Half Beamsize = 1’ Galactic Ring Survey (GRS): Rms<0.4 K; Beamsize ~ 48”

  8. Kes 75 (G29.7-0.3): D (HI) ~ (9, 21kpc); R ~ 1.5 arcmin; Central Plusar + Thermal shell + Non-thermal center; Flux (1 GHz) ~ 10 Jy, Index ~ 0.7

  9. Position: ~ 52-53 km/s; Area: ~ 4-5 Width: ~ 5-7 km/s; Intensity: ~ 0.7-0.8 K

  10. 3C396 (G39.2-0.3) D (HI) > 7.7 kpc; Size ~ 8 * 6 arcmin; Shell + Bright to W; Flux (1 GHz) ~ 18 Jy, Index ~ 0.6
