Two kinematically distinct old globular cluster populations in the Large Magellanic Cloud
Andrés E. Piatti, Emilio J. Alfaro, Tristan Cantat-Gaudin
We report results of proper motions of 15 known Large Magellanic Cloud (LMC) old globular clusters (GCs) derived from the Gaia DR2 data sets. When these mean proper motions are gat…
Hierarchical Bayesian approach for estimating physical properties in nearby galaxies: Age Maps (Paper II)
M. Carmen Sánchez-Gil, Emilio J. Alfaro, Miguel Cerviño +3
One of the fundamental goals of modern astrophysics is to estimate the physical parameters of galaxies. We present a hierarchical Bayesian model to compute age maps from images in…
The Gaia-ESO Survey: the origin and evolution of s-process elements
L. Magrini, L. Spina, S. Randich +45
Several works have found an increase of the abundances of the s-process neutron-capture elements in the youngest Galactic stellar populations, giving important constraints to stell…
J-PLUS: The Javalambre Photometric Local Universe Survey
A. J. Cenarro, M. Moles, D. Cristóbal-Hornillos +119
J-PLUS is an ongoing 12-band photometric optical survey, observing thousands of square degrees of the Northern hemisphere from the dedicated JAST/T80 telescope at the Observatorio…
A method for determining the radius of an open cluster from stellar proper motions
Nestor Sanchez, Emilio J. Alfaro, Fatima Lopez-Martinez
We propose a method for calculating the radius of an open cluster in an objective way from an astrometric catalogue containing, at least, positions and proper motions. It uses the…
