1. The rebirth of Supernova 1987A : a study of the ejecta-ring collision
Abstract : Supernovae are some of the most energetic phenomena in the Universe and they have throughout history fascinated people as they appeared as new stars in the sky. Supernova (SN) 1987A exploded in the nearby satellite galaxy, the Large Magellanic Cloud (LMC), at a distance of only 168,000 light years. READ MORE

2. Spectral modeling of nebular-phase supernovae
Abstract : Massive stars live fast and die young. They shine furiously for a few million years, during which time they synthesize most of the heavy elements in the universe in their cores. They end by blowing themselves up in a powerful explosion known as a supernova (SN). READ MORE

3. Observations of young core collapse supernova remnants
Abstract : Studies of young remnants offer an opportunity to test theoretical models of stellar evolution, explosion models and nucleosynthesis, as well as our understanding of the compact objects in the centre of the exploded stars.The first part of the thesis involves observations of the Crab nebula.

4. An X-Ray View of Core-collapse Supernovae
Abstract : A core-collapse supernova (CCSN) is an astronomical explosion that indicates the death of a massive star. From observations, it is clear that a large fraction of all massive stars undergoes supernova (SN) explosions, but describing how SNe explode has remained a challenge for many decades. READ MORE

5. Core-collapse Supernovae : Theory vs. Observations
Abstract : A core-collapse supernova (CCSN) is an astronomical explosion that indicates the death of a massive star. The iron core of the star collapses into either a neutron star or a black hole while the rest of the material is expelled at high velocities. READ MORE
