The relation between velocity dispersions and chemical abundances in RAVE giants
R. Smiljanic, R. S. de Souza
We developed a Bayesian framework to determine in a robust way the relation between velocity dispersions and chemical abundances in a sample of stars. Our modelling takes into acco…
Gaia Data Release 1. Testing the parallaxes with local Cepheids and RR Lyrae stars
Gaia Collaboration, G. Clementini, L. Eyer +588
Parallaxes for 331 classical Cepheids, 31 Type II Cepheids and 364 RR Lyrae stars in common between Gaia and the Hipparcos and Tycho-2 catalogues are published in Gaia Data Release…
A probabilistic approach to emission-line galaxy classification
R. S. de Souza, M. L. L. Dantas, M. V. Costa-Duarte +7
We invoke a Gaussian mixture model (GMM) to jointly analyse two traditional emission-line classification schemes of galaxy ionization sources: the Baldwin-Phillips-Terlevich (BPT)…
On the realistic validation of photometric redshifts, or why Teddy will never be Happy
R. Beck, C. -A. Lin, E. E. O. Ishida +5
Two of the main problems encountered in the development and accurate validation of photometric redshift (photo-z) techniques are the lack of spectroscopic coverage in feature space…
