G189.1+3.0     IC443, 3C157 (Green’s catalogue)

Right Ascension: 06 17 00 Declination: +22 34 Size (/arcmin): 45 Type: C Flux density at 1 GHz (/Jy): 160 Spectral Index: 0.36 Radio: Limb-brightened to NE, with faint

extension to the E. Optical: Brightest to the NE, with faint

filaments outside the NE boundary. X-ray: Shell, brightest to the NE, plus

compact source with nebula. Point sources: X-ray source and nebula

in S. Distance: Mean optical velocity suggests

0.7–1.5 kpc, association with S249 gives 1.5–2 kpc.

1.1.Physical analysis with IC443, such as MCs mass, shock velocity….

2.2.Detailed 12CO 3-2/2-1, 2-1/1-0 ratio

3.3.Use LVG(large velocity gradient) Model to find the temperature, column density of each clump

4.4.Other interesting things:find out why there is double-peak In clump I, 1665/1667 MHz OH maser at clump B….

The shell ^_^: shape:match along with radio, x-ray,

partly match along with 24um IR ^_^:show some broaden in the 12co line,

but with no confident evidence. The East

^_^:shape: 13co1-0 along with radio >_<:Large MC, too conplicated to anlayse

line broaden >_<:No 12co peak in the maser point at

^_^. 12CO along with radio, partly along with X-ray

^_^.High 12co to 13co ratio >_<.no enough evidence to prove

the MC is shocked.

1. Discovered X-ray from ROSAT and XMM

2. Near the MASER velocity, find a shell in the east, which match along with radio,IR and X-ray, and the line show some broadening.

3. We need 12CO 2-1,3-2 observations to find the shocked MCs.
