The conversion of gas into stars is a fundamental process in astrophysics and cosmology.
Stars are known to form from the gravitational collapse of dense clumps in interstellar …

Context. The spiral structure of the Milky Way is not yet well determined. The keys to
understanding this structure are to increase the number of reliable spiral tracers and to …

Context. The APEX Telescope Large Area Survey of the GALaxy (ATLASGAL) is the first
systematic survey of the inner Galactic plane in the sub-millimetre. The observations were …

Abstract Astrometric Very Long Baseline Interferometry (VLBI) observations of maser
sources in the Milky Way are used to map the spiral structure of our galaxy and to determine …

Recently, a comparison between the locations of 6.7-GHz methanol masers and dust
continuum emission has renewed speculation that these masers can be associated with …

We present the fourth portion of a Galactic plane survey of methanol masers at 6668 MHz,
spanning the longitude range 186°–330°. We report 207 maser detections, 89 new to the …

Class II methanol (CH 3 OH) masers are amongst the clearest signposts of recent high-mass
star formation (HMSF). A complete catalogue outlines the distribution of star formation in the …

We present results from the third portion of the Methanol Multibeam Galactic plane survey of
masers at 6668 MHz. It covers the longitude range 330°–345°, yielding 198 masers, of …

Using the 870 μm APEX Telescope large area survey of the Galaxy, we have identified 577
submillimetre continuum sources with masers from the methanol multibeam survey in the …

We present the fifth portion of an unbiased survey of the Galactic plane,| b|≤ 2°, for 6668-
MHz methanol masers. This section of the survey completes the Galactic longitude range …
