Inferring the age of the universe with globular clusters
We present an estimate of the absolute age of 68 galactic globular clusters obtained by
exploiting the distribution of stars in the full color-magnitude diagram. In particular, we jointly …

A Catalogue of infrared star clusters and stellar groups
E Bica, CM Dutra, B Barbuy - Astronomy & Astrophysics, 2003 - aanda.org
We compiled a catalogue of infrared star clusters in the Galaxy, which are most of them
embedded. It condenses the growing literature information. We also include in the sample …

Low-extinction windows in the inner Galactic Bulge
CM Dutra, BX Santiago, E Bica - Astronomy & Astrophysics, 2002 - aanda.org
We built K band extinction maps in the area of two candidate low-extinction windows in the
inner Bulge: W0. 2–2.1 at ()=(0.25°,-2.15°), and W359. 4–3.1 at ()=(359.40°,-3.10°). We …
