From December 18 to 19, 2017, Dr. Bernhard Müller from Monash University (AU) visited the PSO group to discuss open questions in the evolution of massive stars and their explosions as core-collapse supernovae.
On December 14 and 15, 2017, the PSO group organized the XIIth Würzburg workshop on supernovae and stellar hydrodynamics in Heidelberg at HITS. More than 20 researchers from international universities and institutions gathered to discuss new developments in the field and to collaborate on new and existing projects.
From December 12 to 13, 2017, the PSO group hosted Prof. Ariel Goobar from Stockholm University. Ariel is well known for his work on observational cosmology with Type Ia supernovae for which he received several prestigious prizes, including the Gruber Prize in Cosmology 2007 and the Breakthrough Prize in Fundamental Physics in 2014. Ariel visited…Details
Neutron stars are the densest objects in the Universe; however, their exact characteristics remain unknown. Using simulations based on recent observations, a team of scientists including HITS researcher Dr. Andreas Bauswein has managed to narrow down the size of these stars. When a very massive star dies, its core contracts. In a supernova explosion, the…Details
From November 7 to 8, 2017, Dr. Raphael Hirschi from Keele University (UK) visited the PSO group to discuss current topics in stellar evolution modelling.
The European Research Council has awarded HITS astrophysicist Andreas Bauswein an ERC Starting Grant worth approximately 1.5 million euros. Using computer simulations, the aim of the project is to better understand the collisions between neutron stars. These are seen as potential candidates for the formation of heavy elements such as gold, silver and uranium.Details
Jülich Supercomputing Centre grants 28 million CPU hours for simulations of thermonuclear supernovae
Together with colleagues from the Max Planck Institute for Astrophysics in Garching, PSO scientists were awarded 28 million CPU hours on the JUQUEEN supercomputer at Jülich Supercomputing Centre for a collaboration project on the “Progenitor systems of thermonuclear supernovae”. These resources, allocated for November 2017 to October 2018, will be used to run a suite of models…Details
Astrophysicists all over the world are excited by the first detection of gravitational waves and electromagnetic emission from a single cosmic event: the merger of two neutron stars. On August 17, 2017 the super-sensitive laser-antennas of the LIGO/Virgo collaboration detected tiny little ripples in space time that were interpreted as the gravitational-wave signal of a…Details
Upcoming high-cadence transient survey programmes will produce a wealth of observational data for Type Ia supernovae. These data sets will contain numerous events detected very early in their evolution, shortly after explosion. In a recent study, a team around Ulrich Nöbauer from the Max Planck Institute for Astrophysics, including PSO researcher Markus Kromer, used numerical…Details
From August 7 to 9, 2017, the PSO group hosted Shing Chi Leung, post-doc at the Kavli Institute for the Mathematics and Physics of the Universe at the University of Tokyo. Shing Chi works on multi-dimensional hydrodynamics simulations to model stellar explosions. During his visit, he collaborated with several PSO members on models for Type Ia supernovae.
660. WE-Heraeus-Seminar: Supernovae – From Simulations to Observations and Nucleosynthetic Fingerprints
Observations and theoretical models have made impressive progress in understanding supernova explosions thanks to the advent of huge transient surveys and advances in high-performance computing. To consolidate progress, it is important to make specialists in different aspects of supernova research aware of progress and challenges on other fronts. Together with Anders Jerkstrand (Max Planck Institute…Details
