Particle Physics
There are both experimental and theoretical activities in particle
physics at the Kepler Center. The experimental projects aim to
search for physics beyond the standard model and to study the
role of elementary particles in cosmology. With the projects
CRESST and EURECA, the particles forming the dark matter in
the universe shall be directly detected. Novel detection tech-
niques based on superconducting thin films and crystals at very
low temperatures are developed. GERDA searches for the very
rare neutrinoless double beta decay. If detected it would pro-
vide unique information on the neutrino mass by help of the
transition matrix elements. The particle physics theory group
at Tübingen is world leading in the determination of these matrix
elements. The neutrinoless double beta decay would prove the
existence of the so called Leptonflavor number violation, which
could explain the resulting matter – antimatter asymmetry in
the big bang. DOUBLE CHOOZ looks for neutrino oscillation
with a nuclear power plant as neutrino source.
The activities in theoretical particle physics are devoted to the
low-energy regime of quantum chromo dynamics, QCD. We
focus on the explanation of such non-perturbative effects of
strong interaction like confinement of quarks and gluons and
the spontaneous breaking of chiral symmetry. Other activities
are experiments at accelerators in the non-pertubative regime
of QCD. The program aims at exclusive measurements of
reaction processes in electro-magnetic interactions and in
nucleon-nucleon collisions, which among others are important
for the understanding of matrix elements or of chiral symmetry
restoration of hadrons.

Astrophysics
Astronomical observations in the ultraviolet (UV) spectral
region require space-based observatories because the Earth’s
atmosphere is not transparent for UV radiation. The UV Astronomy
group is utilizing space-based observatories, primarily the
Hubble Space Telescope, to perform UV spectroscopy of stars in
order to investigate the late stages of stellar evolution as well as
the physics of accretion processes onto white dwarfs, neutron
stars and black holes. This allows studying matter under most
extreme conditions which are never achievable in terrestrial
laboratories. The group is responsible for the main instrument
for a Russian-led initiative to establish the World Space Obser-
vatory Ultraviolet (WSO/UV): a high-resolution double-echelle
spectrograph which together with the 1.5m primary telescope
mirror. UV spectroscopy is an essential tool to study astro-
physical plasmas in a wide range of temperatures, where the
most important spectral lines of such plasmas are located.
Experimental research is at the core the high energy astro-
physics group of the Kepler Center. We are very actively devel-
oping X-ray space observatories like the Simbol-X (launch in
2014), the eRosita (2013) and the XEUS missions (after 2018).
But the group is also involved in developments of ground based
Cherenkov Telescopes like H.E.S.S. and of the future Cherenkov
Telescope Array-CTA.

General Relativity
The „Theoretical Astrophysics“ group led by Kostas Kokkotas
works on problems related mainly to sources of gravitational
waves and also on the processes generating gamma rays and
X-rays from neutron stars and black holes.
Gravitational waves are expected to open a new window for ob-
serving the universe and to provide unique information from
astronomical objects and events that do not emit electromag-
netic radiation. Neutron stars are among the primary sources
and it is expected that via gravitational waves we may under-
stand the details of their structure. The group studies the cre-
ation and the subsequent oscillations of neutron stars and the
instabilities that may be induced via fast rotation. Moreover, the
group is working on problems related to black-hole perturba-
tions and their relation to gravitational waves as well as to thermo-
dynamics and quantum processes near blackholes.

Computational Astrophysics
The Computational Astrophysics group deals with the numerical
modelling of complex astrophysical phenomena. For that
purpose we develop and apply complex numerical algorithms
to solve the time dependent equations of magneto-hydro-
dynamics including radiative transport, and solid state physics.
The group performs intense simulations using highly paral-
lelised state of the art particle and mesh-based codes.
The Computational Astrophysics group we pursue theoretical
analyses to understand the ambient environment in which
planet formation takes place using highly parallelised particle
and mesh-based codes. Major research topics include: Under-
standing the growth of planets in the Solar System and exo-
planetary system. We model the process of planet formation
from μm sized particles to the giant planets and study the evo-
lution of whole planetary systems. We study the structure and
evolution of accretion discs for example in close binary stars
and around young protostars.

Gravitational wave detectors.:
VIRGO (Pisa, Italy) and LISA (space detector)
The research area of the Kepler Center is at the intersections of particle physics, astrophysics, and cosmology. The Kepler
Center is formed by the groups of astrophysics, computational astrophysics, general relativity, and particle physics and com-
bines a rich experimental program with intense theoretical studies. The physics goals are multi-messenger observations of
the universe, using the universe as a laboratory for elementary particles and extreme physical conditions, studying the prop-
erties of elementary particles and their influence to the evolution and the structure of the universe and constructing theoretical
models to understand the processes within our universe.
