5. Foreground conference (FGC2011) - "Understanding Galactic and
    extragalactic foregrounds: A road to success for cosmological
    experiments", 23 - 27 May 2011, in Zadar, Croatia
---------------------------------------------------------------------------

Currently, there are several cosmological experiments (planned and
ongoing) that use low frequency radiation to study the structure, the
evolution, and the origin of our Universe. Among those are cosmic
microwave background radiation experiments (e.g. Planck satellite) and
the redshifted 21cm line of neutral hydrogen from the epoch of
reionization (e.g. LOFAR, GMRT, MWA & SKA). In addition to the main
scientific goals of each experiment, they all have one more thing in
common: prominent Galactic and extragalactic foreground emission that
challenges the observations. Therefore, the success of these
cosmological observations relies on our understanding of the
foregrounds and development of good foreground removal
techniques. Obviously, studying the physical origin of these
foregrounds, whether Galactic or extra-galactic, constitute a very
interesting and exciting field in its own right.

The aim of this meeting is to bring together scientists interested in
three main topics:
- Physics and astrophysics of the low frequency Galactic and
extra-galactic foregrounds;
- influence of these foregrounds on the CMB and EoR observations;
- foreground removal techniques.

During the meeting the observational constraints of the Galactic and
extragalactic foregrounds will be reviewed both in total and polarized
intensity. We will discuss the physics of the foregrounds and their
properties (e.g. Galactic magnetic field, ISM, Faraday rotation,
cosmic ray distribution, disk-halo connections and source
counts). Finally, we will discuss mathematical techniques to fit and
remove spatial and spectral foreground structures.

Registration is open now.  Details about the conference, logistics and
