Next Workshop: The Milky Way: Stars, Gas, Dust and Magnetic Fields in 3D


NEWS: 20120608: Updated Full programme available

This workshop, supported by the GREAT-ESF programme, will take place at the Haus der Astronomie, Heidelberg, Germany: 18-20 June 2012

Meeting Abstract:

By combining the observational data from the Planck foreground maps with Gaia distances and
stellar extinction measurements, a 3D map of the dust distribution within a few kpc can in principle
be constructed. Combining this with radio observations of molecular and neutral hydrogen clouds
can ultimately provide a picture of the distribution of those non-stellar components in our Galaxy
that play a major role in, and reflect the consequences of, star formation and evolution. This is
traced further through stellar chemical composition analysis, as provided in part by the Gaia data
and in part by ground-based data (e.g. the Gaia-ESO spectroscopic survey). This workshop will
bring together scientists with expertise in different types of data - optical, infrared, radio - and in
different components of the Galaxy - stars, dust, magnetic fields - in order to investigate scientific
and technical ways in which we can fruitfully combine these data sets for a better understanding of
the Milky Way. A specific objective is to make concrete steps combining different data sets to
prepare them for scientific exploitation in the Gaia data era.
