Better age estimations using UV-optical colours: breaking the age-metallicity degeneracy

S. Kaviraj, S. -C. Rey, R. M. Rich +3

We demonstrate that the combination of GALEX UV photometry in the FUV (~1530 angstroms) and NUV (~2310 angstroms) passbands with optical photometry in the standard U,B,V,R,I filter…
