A search for hypercompact HII regions in the Galactic Plane
(2019-01-11)
We have carried out the largest and most unbiased search for hypercompact (HC) H II regions. Our method combines four interferometric radio continuum surveys (THOR, CORNISH, MAGPIS, and White2005) with far-infrared and ...
The HP2 Survey - IV. The Pipe nebula : Effective dust temperatures in dense cores
(2018-12-01)
Multi-wavelength observations in the sub-millimeter regime provide information on the distribution of both the dust column density and the effective dust temperature in molecular clouds. In this study, we created high-resolution ...
The excitation mechanisms and evolutionary stages of UWISH2 planetary nebula candidates
(2018-10-01)
We present medium-resolution K-band long-slit spectroscopy of 29 true, likely, possible, and candidate Galactic Plane planetary nebulae (PNe) from the UWISH 2 survey, many of which have only been recently discovered. These ...
Herschel and SCUBA-2 observations of dust emission in a sample of Planck cold clumps
(2018-04-27)
Context. Analysis of all-sky Planck submillimetre observations and the IRAS 100 μm data has led to the detection of a population of Galactic cold clumps. The clumps can be used to study star formation and dust properties ...
