"Neutron star mergers as laboratories for extreme physics"
Speaker:
Prof. Stephan Rosswog
(Physics Department of the University of Hamburg)
Abstract:
With the
advent of gravitational wave-based multi-messenger astrophysics, the
next decade holds an enormous promise to
achieve major progress for a number of
long-standing problems. To name just a
few, these include a census of the merging
compact object populations, the sources of
the heaviest elements in the Universe,
the properties of matter at extreme
densities and temperatures, the sources of
gamma-ray bursts and potential
modifications of Einstein's theory of General Relativity.
With the availability of a broad spectrum
of observational information comes an
increasing demand on the realism of the
theoretical modelling of neutron star mergers,
both in terms of including physical
processes and in terms of spanning large length and
time scales. In this talk I will provide
an overview over our current understanding of
these extreme-physics events.
About the Speaker:
Professor Stephan Rosswog is a full
professor at the Observatory Hamburg, which is
part of the Physics Department of the
University of Hamburg, Germany. He
earned his
PhD in Theoretical Physics at the
University of Basel, Switzerland in 1998 after which
he left Academia to model traffic flow at
the German Aerospace Centre in Cologne,
Germany, before taking up a postdoc
position at the University of Leicester, UK, in 2000.
In 2002 he was awarded a 5-year Advanced
Fellowship of the UK Particle Physics and
Astronomy Research Council. From 2003 to
2012 he was a Professor for Astrophysics
at the Jacobs University in Bremen,
Germany and from 2012 to 2022 he was a faculty
member at the Department of Astronomy at
Stockholm University to which he is still
affiliated. He is the recipient of several
prestigious grants and is interested in the
multimessenger astrophysics of compact
objects, with particular emphasis on numerical
relativity, fluid dynamics,
nucleosynthesis, and electromagnetic transients.
