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.)
6
SWAS (1.4-2.8GHz, chemical composition, Submillimeter Wave Astronomy Satellite ) ISO (2.5-240 um, Infrared Space Observatory ) COSMOS(x-ray radio, Cosmic Evolution Survey) SDSS( Sloan Digital Sky Survey ) Spitzer(10d<|l|<65d, |b|<1d, Galactic Legacy Infrared Mid-Plane Survey Extraordinalire [GLIMPSE])
7
DA530(G 93.3 +6.9 ) IRAS(12,25,60,100)um 0.5-2arcmin / 27x20 arcmin
17
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
20
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
22
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)
25
Sloan Digital Sky Survey 1E0102.2-7219 (SMC 52kpc)
26
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.
27
Spitzer (24,70,160um) 2.4-15 arcsec
