The contribution of the color space in LSST-like photometry for the selection of extragalactic globular cluster candidates
Nicholas Schweder-Souza, Ana L. Chies-Santos, Rafael S. de Souza +16
Globular clusters (GCs) are excellent tracers of their host galaxies' evolutionary histories. Traditional methods for identifying GCs in galaxies rely on cuts over photometric cata…
Euclid: The first statistical census of dusty and massive objects in the ERO/Perseus field
G. Girardi, A. Grazian, G. Rodighiero +175
Our comprehension of the history of star formation at relies on rest-frame UV observations, yet this selection misses the most dusty and massive sources, yielding an incomple…
