Infrared SNRs in the Spitzer Space Telescope
astro-ph/0509786(APJL, Snezana Stanimirovic et al.)
astro-ph/0510518(JKAS, Ho-Gyu Lee)
astro-ph/0510630(AJ, Reach & Rho et al.)
SWAS (1.4-2.8GHz, chemical composition,
Submillimeter Wave Astronomy Satellite )
ISO (2.5-240 um, Infrared Space Observatory )
COSMOS(x-rayradio, Cosmic Evolution Survey)
SDSS( Sloan Digital Sky Survey )
Spitzer(10d<|l|<65d, |b|<1d, Galactic Legacy Infrared
Mid-Plane Survey Extraordinalire [GLIMPSE])
• DA530(G 93.3 +6.9 )
• IRAS(12,25,60,100)um
• 0.5-2arcmin / 27x20 arcmin
1. IRAS: 12+(10)/70 (8), Arendt 1989
14+(4)/75 (8), Saken et al. 1992
2. MSX: 8/200 (5), Kim et al. 2005
3. 2MASS: (Crab, IC 443, Cas A, RCW 103)
4. Spitzer: 8+(5+3)/100, Lee 2005JKAS
13+5+(17)/95 , Reach & Rho 2005AJ
• A. shock-heated dust grains, line emission,
synchrotron emission.
(molecular or ionic shocks or PAH emission)
• B. complete or partial shells, partial filaments
or combination filaments
generally coincide with the radio continuum
1. HII regions of the galactic plane(~8um),
PAH(~8um), star light (~3.6um)IPAC tell
us little information about dust emission
2. Molecular shock =/= OH masers(more
strict)
Sloan Digital Sky Survey
1E0102.2-7219 (SMC 52kpc)
1. The 24 um distribution decreases less sharply
than the X-ray distribution.
2. IR emission peaks around 24um(OIV25.88um,
FeII25.98um [RCW103, CasA]), and sharply
falls off toward shorter and longer
wavelengths.
• Spitzer (24,70,160um)
• 2.4-15 arcsec
