This is a personal page for me to share information about myself and my work. Have a nice stay!
My name is Beatrice Giudici and I am a PostDoc at Universitat de València.
I am interested in supernova explosions and how the explosion connects to the star that originated it. In order to explore all the aspects of these fascinating phenomena, I rely on numerical simulations.
In my free time, I am an avid reader, I play videogames, and I love climbing and hiking. I also very much enjoy to play Dungeons and Dragons, actively playing in 3 campaings at the moment.
I focus on numerical simulations of supernova explosions generated by red supergiant progenitor stars. In particular, I am interested in long time scales, before the supernova turns into a supernova remnant. These times are perfect for studying the development of instabilities within the progenitor star, as well as the nuclear reactions happening during the evolution of the ejecta outside of the progenitor, such as the beta decay of 56Ni and 44Ti.
An open question in supernova physics is how to relate the explosion properties with properties of the progenitor star. During my PhD I worked on this aspect, finding a relation between explosion-related properties and the internal structure of the progenitor stars, in particular the radial profile of the density in the He and H shells. The road is still long though, as more complex stellar models are needed to consolidate these findings.
More recently, while still being interested in long-time simulations, I also shifted my focus on the early times. In particular, I am interested in new approximation for the neutrino physics. This is a key point in prolonging the simulations, since neutrino transport scheme can be computationally expensive. In order to prolong the simulations for more than a few seconds, approximations must be used. However, they can be tricky, as they have to be able to capture the physics without being too computationally expensive.
