Masterclasses in Relativistic Fluid Dynamics: From formulation to simulation
In July 16th-19th 2019, our collaborators at the University of Southampton organised a series of lectures by internal and external speakers about relativistic fluid dynamics and applications to the physics of neutron stars. The event brought in speakers and students from several Indian institutions to discuss a range of topics relevant to the modelling and numerical simulation of fluids in a live spacetime. The includes the underlying physics (starting from fundamental principles) as well as advanced topics (like superfluidity, dissipation and resistivity) and practical issues relating to numerical simulations (different numerical methods and approached to spacetime evolutions.
Practical “exercises’ drew on the extensive material available within the Einstein Toolkit and the Open Astrophysics Bookshelf and selected depending on the interests of the students. The event was to be interactive as possible (as we also want to learn!), and gratefully accepted contributions from as many of the participants as possible.
The aim of the masterclass was to explain what enters into state- of-the-art numerical relativity simulations of neutron star mergers and investigate what is required in order to develop more realistic simulations. Students were given the opportunity to present their own research in an informal and collaborative set up.
Various experts in the field were invited to take part and give the lectures, such as LIGO member, Greg Comer. Students attending the masterclass were from India, China and the U.K
