Accretion Signatures from Massive Young Stellar Objects
, 2004 High resolution (lambda / Delta-lambda = 50,000) K-band spectra of massive, embedded, young stellar objects are presented. The present sample consists of four massive young stars located in nascent clusters powering Galactic giant H II regions.

An unstable truth: how massive stars get their mass [PDF]
, 2016 The pressure exerted by massive stars' radiation fields is an important mechanism regulating their formation. Detailed simulation of massive star formation therefore requires an accurate treatment of radiation.

Massive star formation: Nurture, not nature
, 2004 We investigate the physical processes which lead to the formation of massive stars. Using a numerical simulation of the formation of a stellar cluster from a turbulent molecular cloud, we evaluate the relevant contributions of fragmentation and ...

On the ongoing multiple blowout in NGC 604 [PDF]
, 2000 Several facts regarding the structure of NGC 604 are examined here. The three main cavities, produced by the mechanical energy from massive stars which in NGC 604 are spread over a volume of 10$^6$ pc$^3$, are shown here to be undergoing blowout into the

A Brief Galactic Winds and the Role Played by Massive Stars [PDF]
, 2017 Galactic winds from star-forming galaxies play at key role in the evolution of galaxies and the inter-galactic medium. They transport metals out of galaxies, chemically-enriching the inter-galactic medium and modifying the chemical evolution of galaxies.

Young, Massive Star Candidates Detected throughout the Nuclear Star Cluster of the Milky Way
, 2012 Aims. Young, massive stars have been found at projected distances R < 0.5 pc from supermassive black hole, Sgr A* at the center of our Galay. In recent years, increasing evidence has been found for the presence of young, massive stars also at R > 0.5 pc.

Signatures of Mass Segregation from Competitive Accretion and Monolithic Collapse
The Astrophysical JournalThe two main competing theories proposed to explain the formation of massive (>10 M _⊙ ) stars—competitive accretion and monolithic core collapse—make different observable predictions for the environment of the massive stars during, and immediately after,
