Characterising radio sources in the Small Magellanic Cloud using citizen science and optical spectroscopy
For several years, the Small Magellanic Cloud (SMC) has been extensively studied in multiple wavelengths, revealing rich populations of radio sources within and beyond the nearby dwarf galaxy. With radio interfer-ometers' ever-increasing sensitivity and resolution, greater source populations will …

Optical and X-ray studies of Be/X-ray binaries in the Small Magellanic Cloud
… sources in the sky. The growing opulation of Small Magellanic Cloud (SMC) Be/X-ray binaries is monitored weekly with two 15ks RXTE observations. My thesis focuses on presenting the analysis of the X-ray data and the optical follow-up that enhances it. I present detailed studies of the H …

An astrophysical investigation of four classical cepheid variable stars
… and the brightnesses of cepheid variables in the Small Magellanic Cloud, these stars have been an extremely important source of distance information in astronomy . Numerous attempts were made following this discovery to calibrate the period-luminosity law and apply it to problems of galactic …

The effective temperatures and physical properties of red supergiants : the effects of metallicity.
… supergiants (RSGs) in our galaxy, 39 RSGs in the Small Magellanic Cloud (SMC), and 36 RSGs in the Large Magellanic Cloud (LMC). The new effective temperature scales derived from these data are significantly warmer than those in the literature. The known distances of these stars allows a critical …

XMM-Newton Survey of the Magellanic Bridge
… of age, metallicity, and stellar density) in the Magellanic Bridge, the interconnecting region between the Small and Large Magellanic Cloud. Gardiner and Noguchi (1996) suggest that closest approach between Small and Large Magellanic Cloud, as evidenced by dramatic phase shift in star formation, …

Accreting Compact Objects in Technicolor: Multiwavelength Characterization of High Mass X-ray Binaries in the Local Group
… of HMXBs in Local Group galaxies M31 and the Small Magellanic Cloud (SMC) and the spatially resolved recent star formation history (SFH) of M33. In M31, I used observations from the Hubble Space Telescope (HST), the Chandra X-ray Observatory, and the Nuclear Spectroscopic Telescope Array …

Multiwavelength studies of classical novae
… of the super-soft state. At the distance of the Small Magellanic Cloud our measurements suggest that SMCN 2016-10a is the brightest nova in the Small Magellanic Cloud and one of the brightest novae on record, with an absolute maximum magnitude of ∼ −10.5 in the V -band. Chapter four is a …

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 …

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 …

Comprehensive analyses of massive binaries and implications on stellar evolution
… analysis of the binary R 145 in the Large Magellanic Cloud (LMC), which was claimed to host the most massive stars known. We were able to disentangle the spectrum of the system, and performed an orbital, polarimetric, and spectral analysis, as well as an analysis of the wind-wind collision …
