    • IAU Symposium No. 242
      ASTROPHYSICAL MASERS AND THEIR ENVIRONMENTS
      March 12-16, 2007, Alice Springs, Australia

      Contact: Jessica M. Chapman Jessica.Chapman@csiro.au

      Objectives:
      This meeting will be the third international symposium on astronomical masers. The first was held in Virginia, US in March 1992, while the second was held in Brazil as an IAU Symposium in March 2001. The meeting will bring together observational astronomers and theoreticians who study masers and their surrounding environments and will address a broad range of astrophysical problems.
      Topics:
      Maser theory; Polarization and magnetic fields; Surveys; Masers and star formation; Stellar masers, circumstellar winds and supernovae remnants; Masers, galactic structure and the Galactic Centre; Masers in AGN environments; Masers and starburst activity; Diagnostics and interpretation in extragalactic environments; New mm and sub-mm masers and future facilities.
      Venue:
      Alice Springs is located in the "Red Centre" of Australia, in an area of outstanding natural beauty next to the MacDonnell Ranges and Simpson Desert.

    • IAU Symposium No. 243
      STAR-DISK INTERACTION IN YOUNG STARS
      (URL to be determined)
      May 21-25, 2007, Grenoble, France

      Contact: Jérôme Bouvier Jerome.Bouvier@obs.ujf-grenoble.fr

      Rationale:
      Disk accretion and jet outflows are intimately associated with the formation of stars and planets. One central issue raised by recent observational studies is the origin of the physical connection between accretion and wind/jet processes. It has become clear that the physical connection takes place within 1 AU of the central star, in a region where the interaction between the star and the inner disk is still poorly understood. The conference intends to review the observational constraints available on the physical processes thought to be at work at the star-disk interface, to confront them with the predictions of the latest numerical and analytical MHD models of star-disk-jet systems, and to explore the consequences of these processes for stellar angular momentum evolution and inner disk structure.
      Objectives:
      The aim of the conference is to gather astronomers from around the world to critically review the MHD processes which are thought to take place within 1 AU of young stellar objects. It will focus on the structure and variability of the inner magnetized disk, the magnetospheric cavity, and the jet launching region. Understanding the structure and evolution of the star-disk interaction region in young stars is critical to our understanding of the star and planetary system formation process.
      Topics:
      A historical perspective; Magnetic field origin and topology; The magnetospheric accretion flow; Jet launching and outflows; Angular momentum transport; Varying the boundary conditions; Summary and concluding remarks.

    • IAU Symposium No. 244
      DARK GALAXIES AND LOST BARYONS
      June 25-29, 2007, Cardiff, United Kingdom

      Contact: Jonathan I. Davies jid@astro.cf.ac.uk

      Justification:
      Given the standard cosmological model there is far more dark matter than baryonic matter in the Universe. Just where this dark matter resides has been open to speculation and observation since Zwicky first showed that the Coma cluster contains more mass than can be accounted for by the luminosity of its galaxies. Later astronomers have tried to quantify the difference between the mass distribution of the Universe as measured by the location of galaxies compared to that of the underlying mass. The current consensus is that the light from galaxies traces the underlying mass reasonably well, but we have little information on the form of the dark mass that must be associated with the known galaxies. If we are to accept the currently favoured Cold Dark Matter models then we must assume, there are many small dark matter halos within and around larger luminous structures. Given that relatively few are optically detected, one is drawn to the conclusion that the majority of self-gravitating mass concentrations in the Universe remain dark.
      Objectives:
      In this IAU symposium we propose to address the theoretical aspects of dark galaxy formation/evolution and the observational constraints that can be placed on the existence of such elusive objects. A dark galaxy may have reached its current invisible state through one of three pathways. First, it may never have had baryons or it may have lost them all. Second, it may contain baryons, but these have not turned into stars. Third, stars may have formed, but they are now very difficult to detect because their total numbers are very low and/or they are spread out over a large area. In each case the galaxy did not receive or it has lost a fraction of its baryon quota. Each of the above types of dark galaxy offer a different observational and theoretical challenge as to its nature and its role in the grand scheme. The objective of the symposium is to bring together many disjoint observations and models' predictions to reach some consensus on the existence and abundance of dark galaxies.
      Topics:
      Theoretical predictions that dark galaxies exist; Theoretical predictions about the nature of dark galaxies; Quasar absorption features in relation to dark galaxies; Weak lensing and its implications for dark galaxies; X-ray observations and dark masses; Disturbed galaxies interpreting the data; The SZ effect and the detection of optically dark structures; 21cm surveys - implications for gas rich optically dark galaxies; The numbers and properties of dark matter dominated dwarf galaxies; Using and developing new instruments and techniques.

    • IAU Symposium No. 245
      FORMATION AND EVOLUTION OF GALAXY BULGES
      July 16-20, 2007, Oxford, United Kingdom

      Contact: Martin Bureau bureau@astro.ox.ac.uk

      Objectives:
      The Symposium will attempt to build a coherent view of galaxy and more specifically bulge formation by combining the currently dominant but somewhat disjoint hierarchical and secular formation scenarios. The Symposium is thus designed to bring together astronomers who work on cosmological simulations and those who focus on internal dynamical processes, astronomers who advocate observations at high redshift and those who favor present-day galaxies, astronomers who study the structure and dynamics of galaxies and those who probe their stellar populations.
      Topics:
      Classical, hierarchical, and secular bulge formation and evolution models; star formation and gas flows; black holes and nuclear activity; integrated and resolved stellar populations; surveys and the high-redshift universe.

The emphasis is on wave and oscillation observations in different observational bands, consolidation of the theory and the observational findings, observations with new and future solar mission, RHESSI, Solar B, STEREO and SDO.
