Massive stars form on different scales ranging from large, dispersed OB associations to compact, dense starburst clusters. The complex structure of regions of massive star formation, and the involved short timescales provide a challenge for our understanding of their birth and early evolution. As one of the most massive and luminous star-forming region in our Galaxy, W49 is the ideal place to study the formation of the most massive stars. By classifying the massive young stars deeply embedded…

Near-infrared spectroscopy of the massive stellar population of W51: evidence for multi-seeded star formation
Context. The interplay between the formation of stars, stellar feedback and cloud properties strongly influences the star formation history of giant molecular clouds. The formation of massive stars
The young stellar content of the giant H II regions M 8, G333.6−0.2, and NGC 6357 with VLT/KMOS
Context. The identification and characterisation of populations of young massive stars in (giant) H II regions provides important constraints on (i) the formation process of massive stars and their
A relation between the radial velocity dispersion of young clusters and their age
The majority of massive stars (> 8 M ) in OB associations are found in close binary systems. Nonetheless, the formation mechanism of these close massive binaries is not understood yet. Using
A Multiwavelength Look at Galactic Massive Star-forming Regions
We present a multiwavelength study of 28 Galactic massive star-forming H II regions. For 17 of these regions, we present new distance measurements based on Gaia DR2 parallaxes. By fitting a
Feedback in W49A diagnosed with radio recombination lines and models
We present images of radio recombination lines (RRLs) at wavelengths around 17 cm from the star-forming region W49A to determine the kinematics of ionized gas in the THOR survey (The H
Cloud Structure of Galactic OB Cluster Forming Regions from Combining Ground and Space Based Bolometric Observations
We have developed an iterative procedure to systematically combine the millimeter and submillimeter images of OB cluster-forming molecular clouds, which were taken by ground based (CSO, JCMT, APEX,
CO spectral line energy distributions in galactic sources: empirical interpretation of extragalactic observations
The relative populations in rotational transitions of CO can be useful for inferring gas conditions and excitation mechanisms at work in the interstellar medium. We present CO emission lines from
Age spreads and the temperature dependence of age estimates in Upper Sco
Past estimates for the age of the Upper Sco Association are typically 11-13 Myr for intermediate-mass stars and 4-5 Myr for low-mass stars. In this study, we simulate populations of young stars to
Galactic Supernova Remnant Candidates Discovered by THOR
Context. There is a considerable deficiency in the number of known supernova remnants (SNRs) in the Galaxy compared to that expected. This deficiency is thought to be caused by a lack of sensitive
Massive young stellar objects in the N 66/NGC 346 region of the SMC
We present HK spectra of three sources located in the N 66 region of the Small Magellanic Cloud. The sources display prominent stellar Brγ and extended H2 emission, and exhibit infrared excesses at λ


Massive star formation in the W49 giant molecular cloud: Implications for the formation of massive star clusters
We present results from JHKs imaging of the densest region of the W49 molecular cloud. In a recent paper (Alves & Homeier 2003, ApJ, 589, L45), we reported the detection of (previously unknown)
The Discovery of a Very Massive Star in W49
Very massive stars (M>100 M$_{\odot}$) are very rare objects, but have a strong influence on their environment. The formation of this kind of objects is of prime importance in star formation, but
In this study, a combination of IRAC, MIPS, Two Micron All Sky Survey, and UKIRT Deep Infrared Sky Survey data was used to identify and classify the young stellar objects (YSOs) and concluded that W49 has the richest population, with seven subclusters of YSOs.
Uncovering the Beast: Discovery of Embedded Massive Stellar Clusters in W49A*
We present subarcsecond J, H, and Ks images (FWHM ~ 05) of an unbiased 5' × 5' (16 × 16 pc) survey of the densest region of the W49 giant molecular cloud. The observations reveal four massive stellar
Near-IR imaging of Galactic massive clusters : Westerlund 2
Context. Most stars in the Galaxy were formed in massive clusters. To understand nature's favorite mode of star formation and the initial stages of the life of most stars one needs to characterize

Star Formation in W49A: Gravitational Collapse of the Molecular Cloud Core Toward a Ring of Massive Stars
High-resolution molecular line and continuum radio images suggest that the core of the W49A star-forming region is undergoing gravitational collapse and a simple model of inside-out gravitational collapse of a once magnetically supported cloud is fit.
