Abstract
A massive star will mark the end of its stellar evolution via a supernova explosion. The energy from this explosion forms an expanding shock wave that interacts with surrounding environment, creating what we know as a supernova remnant (SNR). For a star that has a mass greater than 8 solar masses, this can also lead to the formation of a rapidly rotating neutron star called a pulsar. These objects will emit across the entire electromagnetic spectrum providing a unique window into studying the acceleration and interaction of highly energetic particles called cosmic rays with molecular clouds. In addition, analysing their emission provides an insight into their evolutionary, and dynamical properties. In this talk, I will present recent results in which we used both X-ray and gamma-ray data to shed light on the properties of SNR MSH 11-61A and pulsar PSR J1741-2054.
Coffee and tea will be served 20 minutes prior to the seminar.
