Exploring the Cosmological Frontiers - Perimeter Institute Summer School - 2009
On June 24 - July 1 2009, the Perimeter Institute will be hosting a Summer School on Particle Physics, Cosmology and Strings. This summer school will be the 7th of an ongoing series offered by the Perimeter Institute, in conjunction with the Pacific Institute for Theoretical Physics, the Pacific Institute for the Mathematical Sciences and the Asia-Pacific Institute for Theoretical Physics. This year's edition will focus on early universe cosmology, dark matter and gravitational wave physics. The school will include a series of lectures on each of these topics, as well as guest lectures on key open problems in the field. -

New Lights on Dark Matter - 2009
In the last few years, a new observational window has opened on the dark sector of matter. The recent flood of experimental results on direct and indirect dark matter detection has potentially revolutionized our view of the nature of dark matter. As the non gravitational nature of dark matter may well be revealing itself for the first time, initial results have lead to a reexamination of WIMP physics with the aim of enhancing the annihilation cross section through various means, and encouraged theorists to think of more exotic possibilities. The purpose of this workshop is to bring together leading theorists in this area, as well as representatives of the recent experiments, to encourage the sharing and debating of recent results and approaches to probing and describing the dark matter sector. -

New Prospects for Solving the Cosmological Constant Problem - 2009
The `Cosmological Constant Problem’ is one of most outstanding problems in theoretical physics. It is a significant theme of many current areas of research, both at theoretical level, and at the experimental level, via the increasing observational evidence for dark energy. However, the way researchers address this problem varies tremendously between different scientific communities. The principal aim of this workshop is to bring together leading researchers in neighboring fields, to reach a common understanding of the nature of the problem, and to share the tools used in addressing it. In parallel, this workshop aims at understanding how the different directions in solving the Cosmological Constant Problem are related as well as searching for genuinely new approaches to tackle the question. -
