Characterizing dynamical states of Galactic open clusters with Gaia DR2
(Universidade Federal de Minas GeraisBrasilICX - DEPARTAMENTO DE FÍSICAUFMG, 2021)
The nature of the peculiar Virgo Cluster galaxies NGC 4064 and NGC 4424
(UNIV CHICAGO PRESS, 2006-02)
Using extensive kinematical and morphological data on two Virgo Cluster galaxies undergoing strong nuclear star formation, we show that ram pressure stripping and gravitational interactions can act together on galaxies ...
Clues for the origin of the fundamental metallicity relations - I. The hierarchical building up of the structure
(Oxford University Press, 2007-01)
We analyse the evolutionary history of galaxies formed in a hierarchical scenario consistent with the concordance Lambda cold dark matter (CDM) model focusing on the study of the relation between their chemical and dynamical ...
The nature of extremely red galaxies in the local universe
(Oxford University PressOxford, 2013)
We investigate the nature of extremely red galaxies (ERGs), objects whose colours are redder than those found in the red sequence present in colour–magnitude diagrams of galaxies. We selected from the Sloan Digital Sky ...
Milky Way demographics with the VVV survey I. The 84-million star colour-magnitude diagram of the Galactic bulge
(EDP SCIENCES S ALES ULIS CEDEX A, 2012)
Context. The Milky Way (MW) bulge is a fundamental Galactic component for understanding the formation and evolution of galaxies, in particular our own. The ESO Public Survey VISTA Variables in the Via Lactea is a deep ...

Unveiling short-period binaries in the inner VVV bulge
(Wiley Blackwell Publishing, Inc, 2021-06)
Most of our knowledge of the structure of the Milky Way has come from the study of variable stars. Among these variables, mimicking the periodic variation of pulsating stars, are eclipsing binaries. These stars are important ...
Signatures of AGN-induced Metal Loss in the Stellar Population
(American Astronomical Society, 2021-11)
One way the active galactic nuclei (AGN) are expected to influence the evolution of their host galaxies is by removing metal content via outflows. In this article we present results that show that AGN can have an effect ...
VALES I: the molecular gas content in star-forming dusty H-ATLAS galaxies up to z=0.35
(Oxford University Press, 2017)
We present an extragalactic survey using observations from the Atacama Large Millimeter/ submillimeter Array (ALMA) to characterize galaxy populations up to z = 0.35: the Valparaiso ALMA Line Emission Survey (VALES). We ...
The Gaia-ESO Survey: Churning through the Milky Way
(EDP Sciences, 2018-01)
Context. There have been conflicting results with respect to the extent that radial migration has played in the evolution of the Galaxy. Additionally, observations of the solar neighborhood have shown evidence of a merger ...
