GALFOR

OVERVIEW

GALFOR is a project of Galactic archaeology (ERC-2016-STG, 716082) to address hot topics of modern astrophysics such as the formation of globular clusters and of their multiple stellar populations. We will exploit the unique dataset that the Hubble Space Telescope and the major ground-based facilities have collected for us to investigate a huge number of Galactic and extra-Galactic star clusters and their stellar populations. GALFOR will study the star clusters that we observe today to shed light on the series of events that occurred at high redshift and led to the formation of the globular clusters and of their multiple populations.

PUBLIC CHROMOSOME MAPS OF GLOBULAR CLUSTERS

GALFOR1
The Chromosome Map (ChM) of Globular Clusters is a pseudo for color-color diagram to identify and characterize multiple stellar populations (Milone et al. 2015).
The first catalogs of ChMs of Globular Clusters from the Atlas of Multiple Stellar Populations in Galactic Globular Clusters (Milone et al. 2017) are available here .
The entire sample of ChMs for 58 clusters from (Milone et al. 2017) and Universal ChMs from (Marino et al. 2019) will be soon publicily available on our website.
