| Abstract |
A brief description is given of the GLIMPSE surveys, including the areas
surveyed, sensitivity limits, and products. The primary motivations for
this review are to describe some of the main scientific results enabled
by the GLIMPSE surveys and to note potential future applications of the
GLIMPSE catalogs and images. In particular, we discuss contributions to
our understanding of star formation and early evolution, the
interstellar medium, galactic structure, and evolved stars. Infrared
dark clouds (IRDCs), young stellar objects (YSOs), and infrared
bubbles/H II regions are discussed in some detail. A probable triggered
star formation associated with expanding infrared bubbles is briefly
mentioned. The distribution and morphologies of dust and polycyclic
aromatic hydrocarbons (PAHs) in the interstellar medium are discussed.
Examples are shown from GLIMPSE images of bow shocks, pillars (elephant
trunks), and instabilities in massive star-formation regions. The
infrared extinction law of diffuse interstellar dust is discussed. The
large-scale structure of the Galaxy has been traced by red-clump giants
using the GLIMPSE point-source catalog to reveal the radius and
orientation of the central bar, the stellar radial scale length, an
obvious increase in star counts toward the tangency to the
Scutum-Centaurus spiral arm, the lack of an obvious tangency from star
counts toward the Sagittarius spiral arm, and a sharp increase in star
counts toward the nuclear bulge. Recent results on evolved stars and
some serendipitous discoveries are mentioned. More than 70 refereed
papers have been published based on GLIMPSE data as of 2008 November. |
