We used the Green Bank Telescope to detect molecular lines observed toward Mid-Infrared (MIR) bubbles N62, N65, N90, and N117. The bubbles were selected from Watson et al. (2016) who detected non-Gaussian CS (1-0) emission lines toward the bubbles. T

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 not

A systematic and automated search of the extensive GLIMPSE mid-infrared survey data of the inner Galaxy was carried out to uncover new star clusters. This search has yielded 59 new clusters. Using our automated search algorithm, these clusters were i

We report VLA observations toward IRAS 18566+0408 conducted to determine the nature of the H2CO 6 cm emission line recently detected by Araya and coworkers. Our observations clearly show that the H2CO source is due to maser emission, making IRAS 1856

A survey for H2CO 6 cm emission toward young massive stellar objects has been conducted using the 305 m Arecibo Telescope. We report detection of emission toward IRAS 18566+0408, only the fifth source in the Galaxy known to show H2CO 6 cm emission. A

Examination of early, in-orbit checkout (IOC) images of a portion of the Galactic plane obtained by the Infrared Array Camera (IRAC) aboard the Spitzer Space Telescope revealed the presence of an extended emission nebula with internal structure. The

Ambient interstellar material may become entrained in outflows from massive stars as a result of shear flow instabilities. We study the linear theory of the Kelvin - Helmholtz instability, the simplest example of shear flow instability, in a partiall

Fifty-four ultracompact (UC) H ii regions in the GLIMPSE survey region (jbj < 1 � and 30 � < l < 70 � ) were observed in H2CO and H110� using the 305 m Arecibo telescope. By analyzing H2CO absorption against the UC H ii region continuum emiss

We present 350 μm continuum images of 24 massive star formation regions obtained with the Caltech Submillimeter Observatory equipped with the SHARC focal-plane array. At this wavelength the spatial resolution is 11''. The 350 μm emission is compare
