The results of a master's thesis on the N63A supernova remnant have been accepted for publication in the Monthly Notices of the Royal Astronomical Society.

We perform extensive spectroscopy of the supernova remnant N63A in the Large Magellanic Cloud, using∼43ks Chandra archival data. By analysing the spectra of the entire remnant, we determine the abundance distributions for O, Ne, Mg, Si, and Fe. We de...

The results of a master's thesis on the evolution of the galactic disc have been accepted for publication in the journal Physics and Astronomy Reports.

Age-metallicity relation for the Galactic disc is a crucial tool and to constrain the Galactic chemical evolution models. We investigate the age-metallicity relation of the Galactic disc using the red giant branch stars in the Solar neighbourhood....
