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 leads to a variety of stellar clusters, ranging from low stellar density OB associations to dense, gravitationally bound starburst clusters. Aims. We aimed at identifying the massive stellar content and reconstructing the star formation history of the W51 giant molecular cloud. Methods. We performed… 
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
Testing the role of environmental effects on the initial mass function of low-mass stars
In star formation process, the vital role of environmental factors such as feedback from massive stars and stellar density on the form of the Initial Mass Function (IMF) at low-mass end is yet to be
FOREST unbiased Galactic plane imaging survey with the Nobeyama 45 m telescope (FUGIN). VI. Dense gas and mini-starbursts in the W 43 giant molecular cloud complex
We performed new large-scale $^{12}$CO, $^{13}$CO, and C$^{18}$O $J=$1--0 observations of the W43 giant molecular cloud complex in the tangential direction of the Scutum arm ($l\sim {30^\circ}$) as a
Star cluster formation in Orion A
We introduce new analysis methods for studying the star cluster formation processes in Orion A, especially examining the scenario of a cloud-cloud collision. We utilize the CARMA-NRO Orion survey
Unusual Galactic H ii Regions at the Intersection of the Central Molecular Zone and the Far Dust Lane
Sgr E is a massive star formation complex found toward the Galactic center that consists of numerous discrete, compact HII regions. It is located at the intersection between the Central Molecular

The Massive Stellar Population of W49: A Spectroscopic Survey
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
RCW36 : characterizing the outcome of massive star formation
Context. Massive stars play a dominant role in the process of clustered star formation, with their feedback into the molecular cloud through ionizing radiation, stellar winds, and outflows. The
Near-infrared spectroscopy in NGC 7538
Aims. The characterisation of the stellar population in young high-mass star-forming regions allows fundamental cluster properties like distance and age to be constrained. These are essential when
AGE SPREAD IN W3 MAIN: LARGE BINOCULAR TELESCOPE/LUCI NEAR-INFRARED SPECTROSCOPY OF THE MASSIVE STELLAR CONTENT*
We present near-infrared multi-object spectroscopy and JHK(s) imaging of the massive stellar content of the Galactic star-forming region W3 Main, obtained with LUCI at the Large Binocular Telescope.
Near-infrared spectroscopic observations of massive young stellar object candidates in the Central Molecular Zone
We present a spectroscopic follow-up of photometrically-selected young stellar object (YSO) candidates in the Central Molecular Zone of the Galactic center. Our goal is to quantify the contamination
Massive pre-main-sequence stars in M17
The formation process of massive stars is still poorly understood. Massive young stellar objects (mYSOs) are deeply embedded in their parental clouds; these objects are rare, and thus typically

An ~800 arcmin2 mosaic image of the W3 star-forming complex obtained with the Chandra X-Ray Observatory gives a valuable new view of the spatial structure of its young stellar populations. The
THE MASSIVE STAR CONTENT OF NGC 3603
We investigate the massive star content of NGC 3603, the closest known giant H II region. We have obtained spectra of 26 stars in the central cluster using the Baade 6.5 m telescope (Magellan I). Of

We present the results of an extensive observational study of the active star-forming complex W51 that was observed in the J = 2 – 1 transition of the 12CO and 13CO molecules over a 125 × 100 region
The roles of stellar feedback and galactic environment in star-forming molecular clouds
Feedback from massive stars is thought to play an important role in the evolution of molecular clouds. In this work, we analyse the effects of stellar winds and supernovae (SNe) in the evolution of
