The Gaia-ESO Survey: Probing the lithium abundances in old metal-rich dwarf stars in the Solar vicinity
M. L. L. Dantas, G. Guiglion, R. Smiljanic +14
We test a scenario in which radial migration could affect the Li abundance pattern of dwarf stars in the solar neighbourhood. This may confirm that the Li abundance in these stars…
The Gaia-ESO Public Spectroscopic Survey: Motivation, implementation, GIRAFFE data processing, analysis, and final data products
G. Gilmore, S. Randich, C. C. Worley +165
The Gaia-ESO Public Spectroscopic Survey is an ambitious project designed to obtain astrophysical parameters and elemental abundances for 100,000 stars, including large representat…
The Gaia-ESO Public Spectroscopic Survey: Implementation, data products, open cluster survey, science, and legacy
S. Randich, G. Gilmore, L. Magrini +161
In the last 15 years different ground-based spectroscopic surveys have been started (and completed) with the general aim of delivering stellar parameters and elemental abundances f…
How have astronomers cited other fields in the last decade?
Michele Delli Veneri, Rafael S. de Souza, Alberto Krone-Martins +3
We present a citation pattern analysis between astronomical papers and 13 other disciplines, based on the arXiv database over the past decade (). We analyze 12,600 ast…
Photometric redshifts for the S-PLUS Survey: is machine learning up to the task?
E. V. R. Lima, L. Sodré, C. R. Bom +14
The Southern Photometric Local Universe Survey (S-PLUS) is a novel project that aims to map the Southern Hemisphere using a twelve filter system, comprising five broad-band SDSS-li…
The Fornax Cluster through S-PLUS
A. V. Smith Castelli, C. Mendes de Oliveira, F. Herpich +25
The Southern Photometric Local Universe Survey (S-PLUS) aims to map 9300 deg of the Southern sky using the Javalambre filter system of 12 optical bands, 5 Sloan-like…
Women in academia: a warning on selection bias in gender studies from the astronomical perspective
M. L. L. Dantas, E. Cameron, Rafael S. de Souza +13
The recent paper by AlShebli et al. (2020) investigates the impact of mentorship in young scientists. Among their conclusions, they state that female protégés benefit more from mal…
UV upturn versus UV weak galaxies: differences and similarities of their stellar populations unveiled by a de-biased sample
M. L. L. Dantas, P. R. T. Coelho, P. Sánchez-Blázquez
The ultraviolet (UV) upturn is characterised by an unexpected up-rise of the UV flux in quiescent galaxies between the Lyman limit and 2500Å. By making use of colour-colour diagram…
AGN dichotomy beyond radio loudness: a Gaussian Mixture Model analysis
Pedro P. B. Beaklini, Allan V. C. Quadros, Marcio G. B. de Avellar +2
Since the discovery of Quasi-stellar Objects (QSOs), also known as quasars, they have been traditionally subdivided as radio-loud and radio-quiet sources. Whether such division is…
The miniJPAS survey: a preview of the Universe in 56 colours
S. Bonoli, A. Marín-Franch, J. Varela +166
The Javalambre-Physics of the Accelerating Universe Astrophysical Survey (J-PAS) will soon start to scan thousands of square degrees of the northern extragalactic sky with a unique…
The S-PLUS: a star/galaxy classification based on a Machine Learning approach
M. V. Costa-Duarte, L. Sampedro, A. Molino +32
We present a star/galaxy classification for the Southern Photometric Local Universe Survey (S-PLUS), based on a Machine Learning approach: the Random Forest algorithm. We train the…
UV bright red-sequence galaxies: how do UV upturn systems evolve in redshift and stellar mass?
M. L. L. Dantas, P. R. T. Coelho, R. S. de Souza +1
The so-called ultraviolet (UV) upturn of elliptical galaxies is a phenomenon characterised by the up-rise of their fluxes in bluer wavelengths, typically in the 1,200-2,500A range.…
The Southern Photometric Local Universe Survey (S-PLUS): improved SEDs, morphologies and redshifts with 12 optical filters
C. Mendes de Oliveira, T. Ribeiro, W. Schoenell +142
The Southern Photometric Local Universe Survey (S-PLUS) is imaging ~9300 deg^2 of the celestial sphere in twelve optical bands using a dedicated 0.8 m robotic telescope, the T80-So…
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)…
Is the cluster environment quenching the Seyfert activity in elliptical and spiral galaxies?
R. S. de Souza, M. L. L. Dantas, A. Krone-Martins +7
We developed a hierarchical Bayesian model (HBM) to investigate how the presence of Seyfert activity relates to their environment, herein represented by the galaxy cluster mass, $M…
