Large current and upcoming observing programmes (e.g. Planck, SPT,
KiDS, DES, HSC, DESI, eROSITA, LSST, Euclid) provide a wealth of
information for cosmological and astrophysical investigations.
Constraints on the dark sector (dark matter & dark energy)
can be obtained via various cosmological probes,
such as galaxy clusters, weak gravitational lensing,
baryon acoustic oscillations, redshift space distortions,
and type Ia supernovae.
For many techniques advances in cosmological constraints
are closely linked to advances in our understanding of astrophysical
processes and contaminants (e.g. intrinsic galaxy alignments, the influence
of baryons on the matter power spectrum, the impact of cluster astrophysics
on scaling relations between cluster observables and mass, etc.).
Observational data can provide constraints on these effects,
which can then be compared to results from simulations to test the underlying
astrophysical models, yielding more
robust model predictions for cosmological exploitation.
This illustrates the links between astrophysics and cosmology, and the importance of bringing observers,
theorists, and simulators together.
Aim of the splinter:
We would like to use this splinter to bring together the
various groups working within this broad range of topics
in Germany and the Netherlands
(but of course participants from other countries are also very welcome to join).
The splinter should provide an opportunity to present recent
work, highlight efforts regarding ongoing major projects, and foster
collaborations between the teams.
We encourage the members of the community to submit abstracts
for contributed presentations ranging from thesis results to
overview talks for major projects.
We also plan to allocate some time for a broader discussion,
e.g. regarding the current and future situation of this field
of research within Germany and the Netherlands.
Abstract submission and registration:
Abstracts need to be submitted via the main website of the AG Meeting https://www.ag2016.de, and should link to the GCC splinter.
The deadlines for the registration for the AG Meeting are
July 30th (regular fee) and August 26th (late fee).
The deadline for abstract submission for this splinter is August 26th.

Please feel free to contact us at ag2016-gcc(at)astro.uni-bonn.de if you have any questions regarding this
splinter, or suggestions, e.g. for the discussion.
We hope to see many of you in Bochum!
