چکیده
A mid-infrared atlas of part of the Galactic plane (75 • < l < 148 • , b = ±6 •) has been constructed using HIRES processed infrared data to provide a mid-infrared data set for the Canadian Galactic Plane Survey (CGPS). The addition of this data set to the CGPS will enable the study of the emission from the smallest components of interstellar dust at an angular resolution comparable to that of the radio, millimetre, and far-infrared data in the CGPS. The Mid-Infrared Galaxy Atlas (MIGA) is a mid-infrared (12 µm and 25 µm) counterpart to the far-infrared IRAS Galaxy Atlas (IGA), and consists of resolution enhanced (∼ 0.5 ′ resolution) HIRES images along with ancillary maps. This paper describes the processing and characteristics of the atlas, the cross-beam simulation technique used to obtain high-resolution ratio maps, and future plans to extend both the IGA and MIGA.

A mid-infrared atlas of the Galactic Plane (MIGA) has been constructed to provide a mid-infrared data set for the Canadian Galactic Plane Survey, a Canadian-lead international project to map all of the major components of the interstellar medium of the Milky Way at a common resolution of approximately 1 ′. The atlas is based on HIRES processing of IRAS 12 and 25 µm data. Details of the MIGA pro...

Studies of interstellar dust using the recently completed Mid-Infrared Galaxy Atlas (MIGA) and the soon to be launched Wide-Field Infrared Explorer (WIRE) satellite are summarized. Projects include looking at the distribution of dust around HII regions, the study of dust at the interfaces of HII regions and molecular clouds, and understanding the colour variations seen in cirrus clouds. The Mid...
