Christian David Ott

from Wikipedia, the free encyclopedia

Christian David Ott (* 1977 in Offenbach am Main ) is a German theoretical astrophysicist who is particularly known for research on supernovae .

Career

Ott studied theoretical astrophysics at the University of Heidelberg with a diploma in 2003 with Wolfgang J. Duschl and was awarded summa cum laude in 2007 at the University of Potsdam , where he worked at the Max Planck Institute for Gravitational Physics in Golm near Potsdam, with Bernard Schutz PhD. From 2006 to 2008 he was a post-doctoral student at the Joint Institute of Nuclear Physics (JINA) at the University of Arizona with Adam Burrows and from 2008 to 2009 a Sherman Fairchild Prize Fellow at the California Institute of Technology (Caltech).

In 2009 he worked as an assistant professor at the Niels Bohr Institute and from 2009 as an assistant professor for theoretical astrophysics at Caltech, where he received a tenure track . He was also an Adjunct Assistant Professor at Louisiana State University from 2009 to 2014 . He was a member of the TAPIR ( Theoretical Astrophysics including Relativity ) group at Caltech. In 2017 he resigned from his professorship at Caltech.

In 2017/18 Ott worked at the Yukawa Institute of Theoretical Physics in Kyoto .

Scientific focus

Ott deals with the mechanisms of collapse supernovae (general-relativistic simulation in three spatial dimensions with realistic microphysics, including radiation transport via neutrinos, equations of state for nuclear matter and thermonuclear processes and element formation, role of turbulence), generation of gravitational waves and the resulting signatures of various sources, theory of long gamma-ray bursts (Kollapsar model) and general numerical relativity including scientific computing for massively parallel high-performance computers. He was part of the Simulating eXtreme Spacetimes (SXS) collaboration , contributed to the open source Einstein toolkit for numerical relativity, and is a member of the LIGO collaboration.

In 2006, in his dissertation, he proposed a new mechanism for collapse supernovae (pulsation modes of the proto-neutron star and its damping by acoustic modes), which is also expressed in the signature of gravitational waves. In 2015 he demonstrated in magnetohydrodynamic simulations with Philipp Mösta and others that high magnetic fields can build up in fast rotating massive stars like magnetars (scenario of the Ic supernovae and the formation of long gamma-ray bursts ).

Awards

Ott received the Potsdam Young Scientist Prize in 2007. In 2008 he was awarded the Otto Hahn Medal of the Max Planck Society . In 2012 he received an NSF Career Grant. From 2012 to 2014 he was a Sloan Fellow .
