Session 1: Computational astrophysics and cosmology in the exascale era: challenges and limitations
- Salvatore Cielo (Leibniz Supercomputing Centre)
Cosmological hydrodynamical simulations are an indispensable and uniquely powerful tool to link fundamental parameters of cosmological theories with small scale astrophysics, thereby allowing predictions of numerous observables far into the non-linear regime. In the future we seek to build up on successful recent calculations such as IllustrisTNG by expanding the physical faithfulness of the...
The calculation of gravitational interactions scales with the number of particles squared. This creates enourmous computational demands with large number of particles. To mitigate this issue multiple algorithms, such as tree or grid approaches, have been used in the past to reduce the computational costs and to allow for larger simulations with larger numbers of particles. While these...
The GRAVITY instrument made a remarkable observation during the Near-Infrared flares of 2018, detecting a fast-moving hot spot in what seemed to be a circular orbit around SgrA*, the supermassive black hole in our Galactic Center. These profound observations have motivated the development of an advanced Python code for General-Relativistic Radiative Transfer calculations within the framework...
The dynamical evolution of planetary objects in stellar clusters is still an uncharted territory, and observation of planets in general are extremely limited. In this talk, I will first explain how these objects are created, and then numerically explore the dynamical evolution of such objects, using different stellar cluster densities. The main objective will be to understand if the dynamical...
