Dynamics of ionized and neutral gas in M8
We present a spectroscopic study of the dynamics of the ionized and neutral gas throughout the Lagoon nebula (M8), using VLT/FLAMES data from the Gaia-ESO Survey. We explore the... -
ALMA view of G351.77-0.54
The fragmentation of high-mass gas clumps and the formation of the accompanying accretion disks lie at the heart of high-mass star formation research. We resolve the small-scale... -
Radio spectra of globulettes in Carina nebula
The Carina nebula hosts a large number of globulettes. An optical study of these tiny molecular clouds shows that the majority are of planetary mass, but there are also those... -
Millimeter RRL in ATLASGAL-selected massive clumps
Observations of millimeter wavelength radio recombination lines (mm-RRLs) are used to search for HII regions in an unbiased way that is complementary to many of the more... -
Hi-GAL cluster candidates physical properties
The aims are to investigate the clustering of the far-infrared sources from the Herschel infrared Galactic Plane Survey (Hi-GAL) in the Galactic longitude range of -71 to... -
Combined ArTeMiS+SPIRE 350um image of NGC6334
Herschel observations of nearby molecular clouds suggest that interstellar filaments and prestellar cores represent two fundamental steps in the star formation process. The... -
W51 Main NH_3_ and CH_3_OH data cubes
This paper is the third in a series of NH_3_ multilevel imaging studies in well-known, high-mass star-forming regions. The main goal is to characterize kinematics and physical... -
SN II in host HII regions
Spectral modelling of typeII supernova atmospheres indicates a clear dependence of metal line strengths on progenitor metallicity. This dependence motivates further work to... -
Halpha images of NGC 6334 and NGC 6357
We analyze the Halpha emission of the star-forming region NGC 6334 and NGC 6357 with the aim to precise/determine the nature of the HII regions. Cone search capability for table... -
Gum 31 870um continuum image
We are presenting here a study of the cold dust in the close environs of the ring nebula Gum 31. We aim at deriving the physical properties of the molecular gas and dust... -
3D observations of S 140
The objective of this work is to study in detail the temperatures of dust and gas in the photon-dominated region S140, especially around the deeply embedded infrared sources... -
M17-SW datacubes in C and CO lines
We probe the column densities and masses traced by the ionized [CII] and neutral [CI] atomic carbon with spectrally resolved maps, and compare them to the diffuse and dense... -
Molecular gas associated with IRAS 10361-5830
We analyze the distribution of the molecular gas and dust in the molecular clump linked to IRAS 10361-5830, located in the environs of the bubble-shaped HII region Gum 31 in the... -
G53.541-0.011 ^12^CO and ^13^CO data cubes
To investigate how a large-scale infrared bubble centered at l=53.9{deg} and b=0.2{deg} forms, and to study if star formation is taking place at the periphery of the bubble, we... -
W3(OH) high angular resolution 7mm images
Recent high angular resolution radio observations of the ultracompact Hii region W3(OH) confirm the presence of an extremely compact (0.05"), time-variable source near its... -
Globulettes in the Carina nebula
Small molecular cloudlets are abundant in many HII regions surrounding newborn stellar clusters. In optical images these so-called globulettes appear as dark silhouettes against... -
Anomalous microwave emission in Galactic clouds
Anomalous microwave emission (AME) is believed to be due to electric dipole radiation from small spinning dust grains. The aim of this paper is a statistical study of the basic... -
SMC blob N26 multiband photometry
High-excitation compact HII regions of the Magellanic Clouds are sites of recent massive star formation in low metallicity environments. Detailed study of these regions and... -
Chandra X-ray observation of Gum 31
Gum 31 is a prominent, but still rather poorly studied HII region around the stellar cluster NGC 3324 at the northwestern periphery of the Carina nebula complex. Our aim was to... -
Cometary HII regions of DR21
We present deep Very Large Array H66{alpha} radio recombination line (RRL) observations of the two cometary HII regions in DR 21. With these sensitive data, we test the "hybrid"...
