Astronomy at high angular resolution

Recent years have seen a huge development in high-resolution astronomical techniques, which are critical to progress in many different areas of astronomy. These techniques can be divided in direct methods (Adaptive optics, lucky imaging), interferometry (including speckle imaging and spectro-astrometry), and reconstruction methods (astrotomography). This workshop aims at bringing together the different communities working on these fields and increase the synergies between them. It is indeed often necessary to combine all these techniques together in order to have a coherent and comprehensive idea of all the processes at work in a given astronomical environment.

12° European VLBI Network Symposium and Users Meeting

The 12th European VLBI Network Symposium and Users Meeting will be held from 7th to 10th of October in Cagliari (Italy). The latest scientific results and technical developments from VLBI, and, in particular, e-VLBI and space-VLBI (RadioAstron) results will be reported. The timing of this meeting coincides with the first successful observational tests of the Sardinia Radio Telescopes within the EVN, and with a number of results from new and upgraded radio facilities around the globe, such as e-MERLIN, ALMA, and the SKA pathfinders. This meeting will also incorporate the EVN Users meeting.

IAU 309: Galaxies in 3D across the Universe

A new epoch with unbiased investigations of intrinsic properties of galaxies and their evolution has just started. High performance technology in 3D-spectroscopy in the optical/NIR regime and in radio interferometry allows for the first time the efficient mapping of stars, gas, and dust, in galaxies near and far. Detailed measurements of individual objects are complemented by surveys aiming at a full census of galaxies across the local Universe. Reaching out to the limits of the Universe, the evolution of spatially resolved properties is traced along the whole cosmic history. Likewise to these observational campaigns, new computer technology and highly advanced algorithms are exploited for detailed simulations to probe the underlying physical and cosmological connection.

New Windows on Massive Stars

The important outputs of mass, momentum and energy of massive stars strongly modify their environment and make them key agents in the evolution of galaxies during the whole of cosmic history. Their high luminosities make them objects detectable at far distances in the Universe. Massive stars are thus important probes for studying star formation at high redshifts. As the progenitors of core collapse supernovae, of the long soft Gamma Ray Bursts, and of neutron stars and black holes, they are connected with the most intriguing objects in the Universe. Their physics is, however, not yet very well known and such basic understanding as the origin of the various massive star populations (Be-type stars, red and blue supergiants, Luminous Blue Variables, Wolf- Rayet stars) are still matters of debate, as well as the nature of the progenitors of the various types of core-collapse supernovae (type IIP, IIL, IIb, IIn, Ibc).

Topics will include:

  • planets
  • galactic astronomy
  • extragalactic astronomy
  • setting the scene of high resolution at adjacent frequencies
  • vision of future interferometry
  • future prospects and initiatives

CARMA Symposium 2013

The Kavli Institute for Cosmological Physics (KICP) at the University of Chicago will host the 2013 CARMA Science Symposium on July 8-9, 2013. The two-day meeting will feature presentations relevant to the wide range of interdisciplinary science pursued with CARMA. In particular, there will be presentations from the community on potential future directions for CARMA-related research. These presentations include potential collaboration with new observatories, and science for which CARMA is uniquely suited.
