A Molecular Line Investigation of the Interaction between Mid-infrared Bubbles and the Interstellar Medium
Kathryn Devine, Johanna Mori, Christer Watson +2
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) w…
CS emission near MIR-bubbles
C. Watson, Kathryn Devine, N. Quintanar +1
We survey 44 young stellar objects located near the edges of mid-IR-identified bubbles in CS (1-0) using the Green Bank Telescope. We detect emission in 18 sources, indicating youn…
Triggered Star Formation and Dust around Mid-Infrared-Identified Bubbles
C. Watson, U. Hanspal, A. Mengistu
We use Two Micron All Sky Survey, GLIMPSE, and MIPSGAL survey data to analyze the young stellar object (YSO) and warm dust distribution around several mid-infrared-identified bubbl…
Lifting the Dusty Veil II: A Large-Scale Study of the Galactic Infrared Extinction Law
G. Zasowski, S. R. Majewski, R. Indebetouw +8
We combine near-infrared (2MASS) and mid-infrared (Spitzer-IRAC) photometry to characterize the IR extinction law (1.2-8 microns) over nearly 150 degrees of contiguous Milky Way mi…
IR Dust Bubbles II: Probing the Detailed Structure and Young Massive Stellar Populations of Galactic HII Regions
C. Watson, T. Corn, E. B. Churchwell +4
We present an analysis of late-O/early-B-powered, parsec-sized bubbles and associated star-formation using 2MASS, GLIMPSE, MIPSGAL and MAGPIS surveys. Three bubbles were selected f…
