2. Spitzer Analysis of H II Region Complexes in the Magellanic Clouds: Determining
... The close proximity of the Magellanic Clouds allows us to probe the nature of these star forming regions at small spatial scales. ... We present the spatial analysis, via aperture/annulus photometry, of 16 Large Magellanic Cloud (LMC) and 16 Small Magellanic Cloud (SMC) H II region complexes using the Spitzer Space Telescope's IRAC (3.6, 4.5, 8 ЮМm) and MIPS (24, 70, 160 ЮМm) bands. ... The IRAC, MIPS, UV, and HЮБ spatial analysis are compared with the spatial analysis of the TIR. ...
