Topics
1- Observations of metallicity gradients in the Milky Way: nebular probes (PNe, HII regions) and stellar probes (Supergiants, Cepheids, Open Clusters, field stars)
2- The impact of GAIA on Galactic metallicity gradients
3- Observations in the Local Universe: the present state-of-art and the impact of future instrumentation
4- Pushing the envelope: observations at intermediate and high redshifts
5- Chemo-dynamical evolution models: for the cosmological context to the dynamics of stars and gas.
6- Large spectroscopic surveys in the context of metallicity gradients: results for the on-going surveys (e.g., Gaia-ESO, APOGEE, GALAH, CALIFA) and expectations from the forthcoming ones (e.g., WEAVE, 4MOST, MOONS)
7- Galactic phenomena (including, e.g., interactions between galaxies and the effect of environment – clusters vs isolated galaxies) and their effects on gradients
8- Methods to measure the metallicity, e.g. strong line metallicity calibrations vs. direct measurement of the electron temperature, and their impact on metallicity gradients
9- Time evolution of the radial metallicity gradients: from the Milky Way populations, in nearby galaxies and at cosmological times with redshift samples, and the implications of radial migration.
10-Measuring the metal content with dust: the relation between dust and metallicity, and its implication in our knowledge of the gas content.
Rationale
This meeting will be interdisciplinary but very focused, thus ideal for a focus meeting at the GA.
It is timely in view of the recent and future Gaia releases for what the Galactic studies are concerned, and for the extragalactic data sets recently released, and continuing and new surveys.
It will be an ideal forum for discussing the field in the future instrumental landscape, in view of the giant telescopes, and new developments in the theoretical modeling domain.
It will attract scientists from a different array of fields –both form the Galactic and extragalactic communities as well as from the observational and theoretical ones, yet all interested in the science of galaxy evolution.
It touches some contemporary hot topics such as stellar migration, galaxy interactions, and the new instrumentation on the future giant telescopes.
