A revised view of the Canis Major stellar overdensity with DECam and Gaia: new evidence of a stellar warp of blue stars
Julio A. Carballo-Bello, David Martínez-Delgado, Jesús M. Corral-Santana +4
We present DECam imaging combined with Gaia DR2 data to study the Canis Major overdensity. The presence of the so-called Blue Plume stars in a low-pollution area of the color-magni…
The Gaia-ESO survey: the non-universality of the age-chemical-clocks-metallicity relations in the Galactic disc
G. Casali, L. Spina, L. Magrini +36
In the era of large spectroscopic surveys, massive databases of high-quality spectra provide tools to outline a new picture of our Galaxy. In this framework, an important piece of…
Galaxy classification: deep learning on the OTELO and COSMOS databases
José A. de Diego, Jakub Nadolny, Ángel Bongiovanni +19
Context. The accurate classification of hundreds of thousands of galaxies observed in modern deep surveys is imperative if we want to understand the universe and its evolution. Aim…
A catalogue of open cluster radii determined from Gaia proper motions
Nestor Sanchez, Emilio Alfaro, Fatima Lopez-Martinez
In this work we improve a previously published method to calculate in a reliable way the radius of an open cluster. The method is based on the behaviour of stars in the proper moti…
The OTELO survey: Nature and mass-metallicity relation for H emitters at
Jakub Nadolny, Maritza A. Lara-López, Miguel Cerviño +14
A sample of low-mass H emission line sources (ELS) at was studied in the context of the mass-metallicty relation (MZR) and its possible evolution. We drew our sam…
The OTELO survey. I. Description, data reduction, and multi-wavelength catalogue
Ángel Bongiovanni, Marina Ramón-Pérez, Ana Mará Pérez García +21
The evolution of galaxies through cosmic time is studied observationally by means of extragalactic surveys. The OTELO survey aims to provide the deepest narrow-band survey to date…
