I'm a Spanish Astrophysicist living in Switzerland. Between fondues and chocolates I like to study explosive scenarios using the smoothed particle hydrodynamics technique (SPH). My main focus is on Supernova explosions, and I have developed one of the few hydrodynamics codes (SPHYNX) that can simulate in 3D both types of Supernovas: Type Ia and Core Collapse.
I'm also interested in mergers and collisions of stellar objects, like for example compact objects such as white dwarfs and neutron stars, and their relevance for Supernova explosions and gravitational wave emission.
Computational Astrophysics is a very demanding field, where the knowledge on Astrophysics meets the knowledge in high-performance computing (HPC). In that respect I'm also diving deeper in the world of efficient, resilient, and scalable computing, in order to enable more complex, detailed, and longer astrophysical simulations.
Additionally, my current position allows me to get in contact with researchers from different fields, including life sciences, imaging, and computational sciences. In this respect, I'm lucky enough to contribute to truly interdisciplinary projects.
SPHYNX is an open source density-based new-generation Smoothed Particle Hydrodynamics code for Astrophysical applications. This is an always ongoing project. SPHYNX is the result of a work over a span of decades. This is an state-of-the-art smoothed particle hydrodynamics code that includes the latest improvements in the world of SPH.
