M. Bartelmann (Heidelberg), Y. Mellier (Paris), C. Wetterich (Heidelberg)

Evidence is mounting that our Universe is dominated by some form of Dark Energy which drives its accelerated expansion. In addition, most of the matter in the Universe is of an unknown form which may consist of weakly interacting, cold elementary particles. The existence and the nature of Dark Matter and Dark Energy are among the most intriguing puzzles contemporary physics is confronted with. This course is intended to summarise the evidence for Dark Matter and Dark Energy, to explain current and future observations tracking down their nature and distribution, and to describe efforts of theoretical physics to develop models for both Dark Matter and Dark Energy.

2. EuroSummer School, 4-16 June 2006 , MARCOUX, FRANCE "Observation and data reduction with the Very Large Telescope Interferometer"

SCIENTIFIC RATIONALE

With the advent of large and multi-telescope arays in the past years, interferometry has reached a new stage. Interferometers have become a more common tool for astronomical observations. They have long been team instruments equipped with a few telescopes of small diameter. Because interferometers were limited to bright sources and with no imaging capabilities, only stellar physics have benefited from this instrumental breakthrough. This time is over. Thanks to the use of large telescopes, interferometers now allow to study bright as well as relatively faint objects. First observations of active galactic nuclei have been performed with the Keck interferometric Array and with VLTI allowing to study objects which were still point-like until very recently. With the increasingly large number of telescopes, interferometers are on the verge to reconstruct complex images at an unprecedented angular resolution. Interferometric facilities are becoming more and more open to non-specialist astronomers. The VLTI is a very good example. Three instruments have been opened to the astronomical community : VINCI (until 2004), MIDI and AMBER. It is one of the most powerful interferometers with four 8-m telescopes and four 1.8-meter telescopes, the latter being relocatable on the array allowing an extensive number of configurations for high quality imaging. Although it is still the beginning, VLTI is a success with several tens of astrophysical papers already published. Such a powerful tool is very promising for many astrophysical topics and outstanding science is at hand for astronomers who know how to prepare and use such observations.

SCHOOL OBJECTIVE

The European Southern Observatory (ESO) in collaboration with many European institutes has operated the VLTI since 2002. Institutes in Europe have teamed-up to build a first generation of instruments which are in use and available through calls for observing proposals. The operation of the first VLTI instruments has allowed to train newcomers to this technique. A second generation of more powerful instruments will be available with still better sensitivities and imaging capabilities. However the scientific outcome will be at the same level as the VLTI performance only if astronomers get prepared to interferometric observations and to the use of interferometric data and if the specialists in interferometry transmit their knowledge to the European astronomical community. With this objective in mind, we organize a summer school to train astronomers to the use of the VLTI current generation of instruments.

The objective of the school, beyond learning the basics of interferometry and getting acquainted to the VLTI instruments, is to get practical training of the most important tools required to prepare interferometric observations and to process the data for astrophysical studies. A first school in 2002 had focused on observation preparation. In this sequel, attendees will in particular be trained to data reduction, model fitting and image reconstruction. The goal is that attendees be autonomous to prepare an observing proposal to use MIDI and AMBER and use the data for their own astrophysical studies.

The curriculum of the school consists in general lectures for 30% of the time, practical training for 50% of it and informal seminars for the remaining of the time. A detailed agenda is available on the school web site. The school will take place over two weeks at the Ch‰teau de Goutelas in the center of France from June 4 to June 16.

4. Workshop on Nongaussianity in Cosmology July 24-28 2006, Trieste, Italy

This is to announce a workshop on Nongaussianity in Cosmology July 24-28 2006, to be held in Trieste, Italy. The venue is Hotel Adriatico, overlooking the Adriatic Sea and just next to Miramare Castle and its gardens. Attendance is limited to about 80 participants to encourage informality and there will be plenty of time dedicated to discussions. The primary aim of the workshop is to bring together physicists and astrophysicists with interest in topics such as observational constraints on nongaussianity in cosmic microwave background and large scale structure, novel methods for detection of nongaussianity, theoretical predictions from models of inflation and strings etc. Please bring this announcement to attention of those that may find it relevant.

The workshop is financially supported by ICTP and INFN. There is no registration fee and both food and housing are subsidized by ICTP and relatively inexpensive, but the hotel fills up quickly and early registration is encouraged. More information can be found at the web site www.ictp.trieste.it/~smr1761/, where a continuously updated list of participants can be found. Deadline for registration is April 1st. Financial help is available to participants from developing countries. Further information can be obtained from the school and conference secretariat via email smr1761 at ictp.it.

Prior to this activity there will be a summer school in cosmology and astroparticle physics July 10-21 at the same location. It is targeted to beginning graduate students and other non-experts with interest working in these fields. The web site for this activity is http://cdsagenda5.ictp.trieste.it/full_display.php?smr=0&ida=a05213 , where the list of lecturers can be found. Please encourage your students and others to participate.

5. KITP program, Jan 29, 2007 - Jun 1, 2007 , Santa Barbara , USA "Accretion and Explosion: the Astrophysics of Degenerate Stars"

We are writing to announce the program "Accretion and Explosion: the Astrophysics of Degenerate Stars" to be held at the Kavli Institute for Theoretical Physics at the University of California, Santa Barbara, in the period January 29-June 1 2007, and to alert you that applications are now being accepted. We also encourage you to inform others who you think might be interested in applying.

This program concentrates on the astrophysics of accretion and explosions on white dwarfs. Though there is agreement that a Type Ia supernovae originates from a thermonuclear instability of a massive white dwarf, the astrophysical scenario remains ambiguous, as does the mode and outcome of the explosion. The medium redshift supernovae surveys are now providing important clues about the environment dependence of supernovae properties, such as spectra and light curves. These will clearly impact empirical methods that have been developed for using the observed properties of these exploding white dwarfs as distance indicators that are widely applied to determine cosmological parameters.

The time is now ripe to pursue the astronomical origins of Type Ia supernovae and their present-day accreting counterparts, the physical processes that lead to increased mass of the degenerate star in a binary pair, the approach to ignition and explosion mechanisms, the production of the light curve and spectrum, and the nucleosynthetic yield. These theoretical efforts will be accelerated by the large amount of data on the supernovae, their accreting progenitors, and their constantly cooling brethren, the isolated white dwarfs. Our aim is to provide a rich environment for the proper understanding of these phenomena in terms of stellar evolution, the physics of mass transfer binaries, and the physics of thermonuclear supernovae.

The application deadline is April 2, 2006. It's necessary for every participant to apply online via the KITP web site http://www.kitp.ucsb.edu/cgi-bin/WebObjects/ITPWeb.woa/ even if we have already corresponded with you about the program.

KITP programs differ from many conferences and workshops in that they create a situation where scientists learn from each other and actually do substantive research, often collaborating with other participants. To foster these interactions, KITP encourages all participants to stay for at least three weeks. We understand, however, that some might not be able to manage such a long visit during the academic year. In some of these cases, we will allow short visits for the purpose of bringing exciting new results to the awareness of the participants.

KITP provides office and computing facilities on its site at UC Santa Barbara and also provides help in finding living accommodations. Some level of financial support will be available, depending on the needs of the participants and availability of funds. Due to space and financial constraints, we may not be able to accommodate your preferred dates. Actual commitments of office space and financial support can be made only by written formal invitations from the KITP Director, David Gross.

If you think you'd like to participate, it will help us with our planning if you could apply early, including your proposed length of stay and any financial requirements. Again, feel free to bring this program to the attention of other interested colleagues.

Sincerely yours,

Lars Bildsten , Rosanne Di Stefano , Robert Kirshner, Craig Wheeler

6. 6th "Rencontres de Moriond", 6th to 12th August 2006, Hanoi, Vietnam "Challenges in Particle Astrophysics"

We would like to call your attention to the 6th "Rencontres de Moriond" which will be held in Hanoi, Vietnam on August 6th through 12th, 2006. The conference will focus on "Challenges in Particle Astrophysics"

The main topics of the meeting will include: Ultra High Energy Cosmic Rays Dark Matter and Dark Energy Cosmology Neutrinos Gravitational Waves

Most of the talks will be plenary talks, but half a day will be devoted to parallel sessions with short talks. More detailed information on the conference can be found on the following Web page: http://vietnam.in2p3.fr/2006/

Here is some background on the meeting series:

Since 1993, "Rencontres du Vietnam" conferences have been organized in Vietnam on various scientific topics, ranging from particle physics to biology and astrophysics. These are international conferences and have in the past brought together some of the world's leading specialists on the specific subjects addressed.

These conferences have, in fact, two purposes:

* The first is, of course, the presentation and analysis of the latest advances and insights in various disciplines.

* But another important motivation is to provide a means for contact between the Vietnamese and Western scientific communities. One might note in this context that young Vietnamese students are very eager to learn and apply science. There is, for example, an active cosmic ray group in Hanoi, led by a well known, retired physicist from CERN.

Please note that in parallel to "Challenges in Particle Astrophysics", another conference on mesoscopic physics and nanotechnologies will be held in the same venue and that the week after, the International Symposium on Very High Energy Cosmic Ray Interactions (ISVHECRI) will be held in Weihai (China).

7. COSPAR SESSION E1.8 , 16-23 July 2006 , Beijing, China "Shedding New Light on Dark Matter and Dark Energy"

The three-day meeting "Shedding New Light on Dark Matter and Dark Energy", session E1.8, will be held during the 36th COSPAR Scientific Assembly, in Beijing, China 16-23 July 2006 at the Beijing Institute of Technology (BIT) and Beijing Friendship Hotel.

Space observations from WMAP, Chandra, XMM-Newton, and HST as well as ground-based surveys are providing fundamental insights about dark matter and dark energy. HST and ground-based observations of lensing, large scale structure, and SN Ia determine dark matter distributions and provide constraints on dark energy. WMAP observations of the CMB provide extremely precise measurements of cosmological parameters. Space-based X-ray observations map dark matter in clusters, groups, and early type galaxies, while X-ray observations of distant cluster samples yield constraints on dark energy, particularly the equation of state, which are complementary to measurements from the CMB and SN Ia. Looking to the future, planned and proposed missions including Planck, ZEUS, JDEM, DUO, and Con-X will further revolutionize the study of dark matter and dark energy.

The dark matter/dark energy meeting will take place over three successive days during the week of the COSPAR assembly. Sessions will focus on:

* Dark Matter Distributions Lensing X-ray Observations

* Constraints on Dark Energy Supernovae CMB Large Scale Structure and Clusters of Galaxies

In addition, the meeting will discuss future programs, both space and ground-based.

Each topic will be introduced by one or two reviews. We invite you to participate in the meeting and to submit abstracts for talks or posters via the COSPAR WWW site (see below).
