The GOGREEN and GCLASS surveys: First data release
(Oxford University Press, 2021-01)
We present the first public data release of the GOGREEN (Gemini Observations of Galaxies in Rich Early Environments) and GCLASS (Gemini CLuster Astrophysics Spectroscopic Survey) surveys of galaxies in dense environments, ...
Mapping the 13CO/C18O abundance ratio in the massive star-forming region G29.96-0.02
(EDP Sciences, 2018-09)
Aims. Estimating molecular abundances ratios from directly measuring the emission of the molecules toward a variety of interstellar environments is indeed very useful to advance our understanding of the chemical evolution ...
Exploring the 13CO/C18O abundance ratio towards Galactic young stellar objects and H II regions
(EDP Sciences, 2018-04)
Aims. Determining molecular abundance ratios is important not only for the study of Galactic chemistry, but also because they are useful to estimate physical parameters in a large variety of interstellar medium environments. ...
The southern photometric local universe survey (S-PLUS): Improved SEDs, morphologies, and redshifts with 12 optical filters
(Oxford University Press, 2019-10)
The Southern Photometric Local Universe Survey (S-PLUS) is imaging ~9300 deg2 of the celestial sphere in 12 optical bands using a dedicated 0.8mrobotic telescope, the T80-South, at the Cerro Tololo Inter-american Observatory, ...
Exploring the nature and synchronicity of early cluster formation in the Large Magellanic Cloud - IV. Evidence for multiple populations in Hodge 11 and NGC 2210
(Wiley Blackwell Publishing, Inc, 2019-07)
We present a multiple population search in two old Large Magellanic Cloud (LMC) Globular clusters, Hodge 11 and NGC 2210. This work uses data from the Advanced Camera for Surveys and Wide Field Camera 3 on the Hubble Space ...
Exploring the nature and synchronicity of early cluster formation in the Large Magellanic Cloud - V. Multiple populations in ancient globular clusters
(Wiley Blackwell Publishing, Inc, 2020-03)
We examine four ancient LargeMagellanic Cloud (LMC) globular clusters (GCs) for evidence of multiple stellar populations using the Advanced Camera for Surveys andWide Field Camera 3 on the Hubble Space Telescope Programme ...
GS100-02-41: a new large H i shell in the outer part of the Galaxy
(EDP Sciences, 2012-02)
Context. Massive stars have a profound effect on the surrounding interstellar medium. They ionize and heat the neutral gas, and with their strong winds they sweep up the gas, forming large H i shells. In this way, they ...
Evolución de Galaxias y QSOs. Modelo evolutivo-explosivo-compuesto: fase final de galaxias y origen explosivo de galaxias enanas
(Asociación Argentina de Astronomía, 2015-08)
En este trabajo presentamos nuevos resultados de nuestro modelo evolutivo-explosivo-compuesto de Galaxias, Cuásares y AGNs. En particular: explicamos el concepto de fase final de una galaxia y el hecho de que al menos una ...
The bright end of the color-magnitude relation
(Asociación Argentina de Astronomía, 2009-01)
Investigamos el origen de la relación color magnitud (RCM) observada en galaxias de tipo temprano residentes en cúmulos, combinando una simulación cosmológica de N-cuerpos y un modelo semianalítico de formación de galaxias ...
The VMC survey - XXV. The 3D structure of the Small Magellanic Cloud from Classical Cepheids
(Wiley Blackwell Publishing, Inc, 2017-08)
The VISTA near-infrared YJK s survey of the Magellanic System (VMC) is collecting deep K s -band time-series photometry of pulsating stars hosted by the two Magellanic Clouds and their connecting bridge. Here, we present ...
