The Zero-Age Massive Stellar Population of W49A from VLA Observations
M. Juárez-Gama, R. Galván-Madrid, G. Suárez +14
We use all-configuration VLA data at 3.3 cm with a physical resolution of ~2000 AU to infer the embedded zero-age massive stellar population of the W49A protocluster, as traced by…

The stellar initial mass function of nearby young moving groups
Rafael Bertolotto-Stefanelli, Juan José Downes, Genaro Suárez +3
The solar neighbourhood is populated by nearby, young moving groups (NYMGs) of stars that are candidates to be remnants of individual stellar clusters and associations, currently d…

Core to ultracompact HII region evolution in the W49A massive protocluster
T. Nony, R. Galván-Madrid, N. Brouillet +10
We aim to identify and characterize cores in the high-mass proto-cluster W49, determine their evolutionary stages and measure the associated lifetimes. We built a catalog of 129 co…
