We present an analysis of wind-blown, parsec-sized, mid-infrared bubbles and associated star formation using the GLIMPSE IRAC, MIPSGAL MIPS, and MAGPIS VLA surveys. Three bubbles from the Churchwell et al. catalog were selected. The relative distribution of the ionized gas (based on 20 cm emission), PAH emission (based on 8 μm, 5.8 μm, and lack of 4.5 μm emission), and hot dust (24 μm emission) is compared. At the center of each bubble there is a region containing ionized gas and hot dust… 
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 bubbles. We identify
Infrared dust bubble CS51 and its interaction with the surrounding interstellar medium
A multiwavelength investigation of the southern infrared dust bubble CS51 is presented in this paper. We probe the associated ionized, cold dust, molecular and stellar components. Radio continuum
Beyond Str\"omgren Spheres and Wind-Blown Bubbles: An Observational Perspective on H II Region Feedback
Massive stars produce copious quantities of ultraviolet radiation beyond the Lyman limit, photoionizing the interstellar medium (ISM) and producing H II regions. As strong sources of recombination-
Mid-infrared shells or bubbles around expanding H ii regions have received much attention due to their ability to initiate a new generation of star formation. We present multi-wavelength observations
An investigation in radio and infrared wavelengths of two high-mass star-forming regions toward the southern Galactic bubble S10 is presented here. The two regions under study are associated with the
Ionized gas properties of the extreme starburst galaxy Haro 11 – temperature and metal abundance discrepancies
Weuse high qualityVLT/MUSEdata to study the kinematics and the ionized gas properties of Haro 11, a well known starburst merger system and the closest confirmed Lyman continuum leaking galaxy. We
Molecular clumps and star formation associated with the infrared dust bubble N131
Aims. The aim is to explore the interstellar medium around the dust bubble N131 and search for signatures of star formation. Methods. We perform a multiwavelength study around the N131 with data
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 young protostars that
Radio emission from the massive stars in the galactic super star cluster Westerlund 1
Aims. Current mass-loss rate estimates imply that main sequence line-driven winds are not suffi cient to strip away the H-rich envelope to yield Wolf-Rayet (WR) stars. The rich transitional
We investigated the physical properties of molecular clouds and star formation (SF) processes around infrared bubbles, which are essentially expanding H ii regions. We performed observations of 13


The Bubbling Galactic Disk
A visual examination of the images from the Galactic Legacy Infrared Mid-Plane Survey Extraordinaire (GLIMPSE) has revealed 322 partial and closed rings that we propose represent partially or fully
Interstellar Weather Vanes: GLIMPSE Mid-Infrared Stellar Wind Bow Shocks in M17 and RCW 49
We report the discovery of six infrared stellar wind bow shocks in the Galactic massive star formation regions M17 and RCW 49 from Spitzer GLIMPSE (Galactic Legacy Infrared Mid-Plane Survey
Outflows from Massive Young Stellar Objects as Seen with the Infrared Array Camera
The bipolar outflow from the massive star-forming cluster in DR 21 is one of the most powerful known, and in IRAC images the outflow stands out by virtue of its brightness at 4.5 μm (band 2). Indeed,
Molecular Outflows and a Mid-Infrared Census of the Massive Star Formation Region Associated with IRAS 18507+0121
We have observed the central region of the infrared-dark cloud filament associated with IRAS 18507+0121 at millimeter wavelengths in CO(J = 1-0), 13CO(J = 1-0), and C18O(J = 1-0) line emission and
Triggered massive-star formation on the borders of Galactic H ii regions ? II. Evidence for the collect and collapse process around RCW 79
We present SEST-SIMBA 1.2-mm continuum maps and ESO-NTT SOFIJHKS images of the Galactic H ii region RCW 79. The millimetre continuum data reveal the presence of massive fragments located in a dust
Chemical self-enrichment of HII regions by the Wolf-Rayet phase of an 85 M☉ star
It is clear from stellar evolution and from observations of WR stars that massive stars are releasing metal-enriched gas through their stellar winds in the Wolf-Rayet phase. Although Hii region
Two-Dimensional Radiative Transfer in Protostellar Envelopes. III. Effects of Stellar Temperature
We model how the mid-IR colors of young stellar objects (YSOs) vary with stellar temperature. The spectral energy distribution (SED) of each object has contributions from the thermal emission of
Triggered massive-star formation on the borders of Galactic H II regions I. A search for "collect and collapse" candidates
Young massive stars or clusters are often observed at the peripheries of H  regions. What triggers star formation at such locations? Among the scenarios that have been proposed, the "collect and

Context. We are engaged in a multi-wavelength study of several Galactic Hii regions that exhibit signposts of triggered star formation on their borders, where the collect and collapse process could
Astrophysics of Dust
Currently ∼36 different absorption bands have been detected in the infrared spectra of cold, dense interstellar and circumstellar environments. These are attributed to the vibrational transitions of
