Exploring the properties of supernovae and other transients

Abstract :

 The transient universe is filled with a rich variety of objects emitting in various regimes of the electromagnetic spectrum. Supernovae are one class of transients that mark the death of stars, wherein heavy elements are forged and dispersed, leading to the galactic enrichment of the Universe. In core-collapse supernovae, the collapse of the inert iron core in massive stars paves the way for the catastrophic explosion. This gives rise to a range of observational signatures owing to the diverse nature of the pre-explosion star and its environment. In my thesis, I have analysed six hydrogen-rich core-collapse supernovae, their progenitors and environment. I have planned three projects that can be carried out during my post-thesis period in ARIES: (1) analyzing the site metallicity of core-collapse supernovae observed with the 1m class telescopes in ARIES during the year 2002-2019, (2) understanding the connection between superluminous supernovae and fast radio bursts, and (3) predicting progenitor properties by modelling the light curves with sophisticated codes such as SNEC. In this talk, I will discuss the outcomes of my thesis work and the research projects that I wish to carry out during my post thesis period.
