Mapping the gamma-ray distributions of the Magellanic Clouds
… of the Milky Way satellites, the Large and Small Magellanic Clouds. Spatial maps used to compare to the Fermi signals are constructed based on three cosmic-ray particle interactions expected to generate gamma rays of energies detectable by Fermi: neutral pion production, bremsstrahlung radiation, …

Multi-wavelength study of neutron stars in the Magellanic Clouds
… study of candidate X-ray binaries in the Large Magellanic Cloud (LMC), resulting in a 50% increase in the confirmed population of accreting neutron stars in the LMC. Following this study, I carry out a targeted radio pulsar search in the Small Magellanic Cloud (SMC), leading to the discovery of …

The relation between atomic and molecular gas: the Magellanic Clouds and beyond
… and molecular gas relation in the Large/Small Magellanic Clouds and 43 nearby galaxies. These galaxies demonstrate various galactic environments compared with the Milky Way and provide an ideal sample for testing the cloud-scale and galactic-scale models of the atomic-to-molecular transition …

A spectroscopic and photometric study of stellar populations in a sample of clusters in the Magellanic Clouds
… of a representative sample of Large and Small Magellanic Cloud (LMC and SMC respectively) clusters. The globular clusters system of these two Irregular galaxies provides a rich resource for investigating stellar and chemical evolution and to obtain a detailed view of the star formation history …

Rare Stellar Populations in the Magellanic Clouds: Identification of Super-Asymptotic Giant Branch Star and Yellow Supergiant Binary Candidates
… methods to identify hundreds of YSGs in the Magellanic Clouds that show signs of a blue/UV photometric excess. This demonstrates that optical/UV photometry can be a robust way to obtain better constraints on YSG binarity using large photometric surveys. Spectroscopic follow-up will still be …

Galactic Structure with Giant Stars
… my Ph.D, focusing on both the Milky Way and the Magellanic Clouds. I deploy long period variables, especially Miras, as chronometers to study the evolution of Galactic structure over stellar age. I study red giants in the Magellanic Clouds, assign them photometric metallicities and map large …

Testing stellar models with observations from AGB and post-AGB stars
… out using three intermediate-age clusters in the Magellanic Clouds. Accurate initial masses and mass loss rates were estimated using the pulsation properties of cluster-AGB stars. Subsequently, updated stellar evolution models constrained with observations of these cluster-AGB stars were …

Massive stars in low metallicity environments
… models. Recent surveys of the galaxy and Magellanic clouds in addition to continuous development of stellar evolution codes are, however, replenishing the domain of massive stars so that we may probe the characteristics of their evolution to better understand the early stages of their …
