1. Star-forming Dwarf Galaxies : Internal motions and evolution
Abstract : The study of dwarf galaxies is important in order to better understand the physics of the young universe and how larger galaxies form and evolve. In this work we focus on Blue Compact Galaxies (BCGs) which havemuch enhanced star formation (starbursts), causing blue colours and strong emission line spectra. READ MORE

2. Multi frequency interferometer studies of active and starburst galaxies
Abstract : We report the results of a multi-frequency study of three interactinggalaxies: NGC 5218, NGC 1614 and NGC 4194 (the Medusa merger). These sourcesbelong to different classes of active and starburst galaxies. READ MORE

3. Investigating the origin of radio emission in nearby starburst galaxies via high-resolution metre and centimetre observations
Abstract : Star formation and galaxy evolution are intimately linked together. A detailed understanding of the physics of star formation can help us explain how galaxies evolve into, for example, our present Milky Way. READ MORE

4. Molecular gas and ionizing radiation in star-forming galaxies
Abstract : In cosmic history, some of the major changes such as reionization were driven by baryons (i.e. the stars and gas in galaxies), despite the fact that they contribute only few percent to the total mass-energy budget in the Universe. READ MORE

5. Radio Studies of Circumnuclear Gas in Active Galaxies
Abstract : In this thesis we have used radio interferometry in order to perform high resolution spectral line studies of circumnuclear gas in AGN and starburst galaxies. Amongst the studied objects is the Seyfert 2 NGC5793, for which we find the high opacity HI absorption to be consistent with a 50-100 pc radius atomic disk aligned with the host galaxy disk. READ MORE
