Understanding Our Universe: Current Status and Open Issues
Last couple of decades have been the golden age for cosmology. High quality
data confirmed the broad paradigm of standard cosmology but have thrusted upon
us a preposterous composition for the universe which defies any simple
explanation, thereby posing probably the greatest challenge theoretical physics
has ever faced. Several aspects of these developments are critically reviewed,
concentrating on conceptual issues and open questions. [Topics discussed
include: Cosmological Paradigm, Growth of structures in the universe, Inflation
and generation of initial perturbations, Temperature anisotropies of the CMBR,
Dark energy, Cosmological Constant, Deeper issues in cosmology.]Comment: To appear in "100 Years of Relativity - Space-time Structure:

10091 Abstracts Collection -- Data Structures
From February 28th to March 5th 2010, the Dagstuhl Seminar 10091 "Data
Structures" was held in Schloss Dagstuhl~--~Leibniz Center for
Informatics. It brought together 45 international researchers to
discuss recent developments concerning data structures in terms of
research, but also in terms of new technologies that impact how data
can be stored, updated, and retrieved. During the seminar a fair
number of participants presented their current research and open
problems where discussed. This document first briefly describes the
seminar topics and then gives the abstracts of the presentations given
during the seminar
