Mat-1.3656 Seminar on numerical analysis and computational science

Miika Oksman, Aalto?
Numerical modelling of electromagnetic radiative phenomena in astrophysical parsec-scale relativistic jets using C++11

- We will briefly discuss what are quasars, active galaxies and relativistic jets and why we can observe some of them from billions of light-years away, i.e., why they are some of the most energetic objects known by science.
- How does one numerically simulate systems that span millions of light-years, but also have interesting magnetohydrodynamic shock effects manifesting in comparatively small areas of few astronomical units? Furthermore how this is done using open-source tools and C++11?
- Aalto Triton high-performance computing cluster is mentioned and some possibilities of multinational supercomputing grids.
- A simple demonstration is provided to illustrate how minuscule the Solar System and our Milky Way galaxy are and how metres (m), astronomical units (AU), light-years (ly) and parsecs (pc) compare to each other.
- The speaker will also modestly experiment with interactive pedagogical methods with the audience to improve social networking, exchange of know-how and the entertainment value of informative academic presentations.
