About: We invite applications for two postdoctoral positions in the area of computational astrophysics in the research group of Dr. Ondřej Pejcha at the Institute of Theoretical Physics, Faculty of Mathematics and Physics, Charles University, Prague, Czechia (https://utf.mff.cuni.cz/~pejcha). The successful candidates will lead the development of advanced computational tools utilizing the discontinuous Galerkin method conduct multi-dimensional simulations of fundamental processes in binary stars (mass transfer and mass loss, accretion, explosions, pulsations, turbulence, mixing, etc.) apply simulation results to specific types of binary systems (tidally-deformed or mass-transferring stars, chemically-homogeneous gravitational wave progenitors, classical novae, Type Ia supernovae, circumbinary disks around supermassive black holes, etc.) pursue original research aligned with the group’s interests, lead high-impact publications engage in the group’s scientific activities, with optional opportunities to mentor students. We encourage candidates with diverse research profiles, from computational tool development to broadly interpreted astrophysical theory, to apply. Experience with hydrodynamics in astrophysics and/or the discontinuous Galerkin method is advantageous but not required. The research group has access to a dedicated computer cluster, which will be soon expanded with new GPU-enhanced nodes. The group has been successful in applying for time on national supercomputing infrastructure with postdocs and students leading the proposals. The group is connected to observational efforts in time-domain astronomy as part of the All-Sky Automated Survey for Supernovae and other theoretical and observational collaborations.       Sponge   Distinct   Permalink
