This review examines the state-of-the-art knowledge of high-mass star and massive cluster
formation, gained from ambitious observational surveys, which acknowledges the multiscale …

Although fundamental for astrophysics, the processes that produce massive stars are not
well understood. Large distances, high extinction, and short timescales of critical …

Context. This study deals with infrared bubbles, the H ii regions they enclose, and triggered
massive-star formation on their borders. Aims. We attempt to determine the nature of the …

Methanol masers are often detected in regions of intense star formation. Several studies in
the last decade indicate that they may even be the earliest signpost of a high-mass star …

We compare the kinematics of M31's satellite galaxies to the mass profiles of the subhaloes
they are expected to inhabit in the Λ cold dark matter (ΛCDM) cosmology. We consider the …

The GLIMPSE and MSX surveys have been used to examine the mid-infrared properties of a
statistically complete sample of 6.7 GHz methanol masers. The GLIMPSE point sources …

Aims. Magnetic fields play a primordial role in the star formation process. The Zeeman effect
on the CN radical lines is one of the few methods of measuring magnetic fields in the dense …

Abstract A new seven-beam 6–7 GHz receiver has been built to survey the Galaxy and the
Magellanic Clouds for newly forming high-mass stars that are pinpointed by strong methanol …

We report trigonometric parallax measurements of masers in the massive star-forming
complex W43 from Very Long Baseline Array observations as part of the Bar and Spiral …

We report the results of a 1.2-mm continuum emission survey toward 131 star-forming
complexes suspected of undergoing massive star formation. These regions have previously …
