The Galactic Starburst Region NGC 3603 : exciting new insights on the formation of high mass stars
… research is addressed by the question "How do high mass stars form?". While most details related to the formation and early evolution of low mass stars are quite well understood today, the basic processes leading to the formation of high mass stars still remain a mystery. There is no doubt that …

The formation of high-mass stars and stellar clusters in the extreme environment of the Central Molecular Zone
The process of converting gas into stars underpins much of astrophysics, yet many fundamental questions surrounding this process remain unanswered. For example -- how sensitive is star formation to the local environmental conditions? How do massive and dense stellar clusters form, and how does this …

Understanding the Earliest Stages of High-mass Star Formation
High-mass star formation, contrary to its low-mass counterpart, remains poorly understood. This project aims to constrain the mechanisms driving the formation of OB stars and their precursors with the analysis of two main fields: Aquila, observed by the Balloon-borne Large-Aperture Submillimeter …

Molecular clouds and star formation in the Inner Galaxy
… formation is crucial for modern astrophysics. Stars form from the gravitational collapse of molecular gas clouds; it is the process by which cold molecular gas is transformed into the stars and planets that make up the many billions of galaxies in the observable Universe. However, there are a …

Celestial Paleontology: The Legacy of Dying Stars
<p>In their death throes, stars dole out their atmospheric material to the interstellar medium in dramatic stellar winds and spectacular explosions. The details of this profound metamorphosis, from star to remnant, play a key role in the next generation of star formation as well as the energetic …

Investigating the presence and properties of circumstellar material in Type I Supernovae
… of the explosive deaths experienced by some stars in supernovae explosions has increased significantly over the last several decades, though many outstanding questions remain. The work presented here is comprised of two projects that seek to answer the role that circumstellar material plays …

X and UV radiation from accreting non-magnetic degenerate dwarfs
"X radiation from degenerate stars is produced by the impact of accreting matter with the stellar surface. The resulting X-ray and UV spectrum gives vital clues about the nature of the underlying star and the extreme conditions of temperature and magnetic field strength that may exist in the …

A COMPARISON OF STAR FORMATION WITHIN THE GALACTIC CENTRE AND GALACTIC DISC
Stars are of fundamental importance to the entire field of astronomy. The conversion of elements and the distribution of energy throughout the lifetime of stars drives the evolution of the Universe. Despite this, we do not have a unified understanding of the formation process for all stars. This …
