We review progress over the past decade in observations of large-scale star formation, with
a focus on the interface between extragalactic and Galactic studies. Methods of measuring …

A precise interstellar dust extinction law is critically important to interpret observations. There
are two indicators of extinction: the color excess ratio (CER) and the relative extinction …

ABSTRACT The c2d Spitzer Legacy project obtained images and photometry with both
IRAC and MIPS instruments for five large, nearby molecular clouds. Three of the clouds …

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 …

We present a survey of the Orion A and B molecular clouds undertaken with the IRAC and
MIPS instruments on board Spitzer. In total, five distinct fields were mapped, covering 9 deg …

We present a uniform mid-infrared imaging and photometric survey of 36 young, nearby, star-
forming clusters and groups using Spitzer IRAC and MIPS. We have confidently identified …

We present a synthesis of the astronomical observations constraining the wavelength-
dependent extinction, emission, and polarization from interstellar dust from UV to microwave …

ABSTRACT The Wide-field Infrared Survey Explorer (WISE) mapped the entire sky at mid-
infrared wavelengths 3.4 μm, 4.6 μm, 12 μm, and 22 μm. The mission was primarily …

Abstract The UKIDSS Galactic Plane Survey (GPS) is one of the five near-infrared Public
Legacy Surveys that are being undertaken by the UKIDSS consortium, using the Wide Field …

Key cosmological applications require the three-dimensional (3D) galaxy distribution on the
entire celestial sphere. These include measuring the gravitational pull on the Local Group …
