UV bright red-sequence galaxies: a comparative study between UV upturn and UV weak systems
M. L. L. Dantas
Ultraviolet (UV) emission from galaxies is associated with hot components, whether from stellar sources or not. By making use of colour-colour diagrams, early-type galaxies (ETGs)…
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…
Clues on the history of early-type galaxies from SDSS spectra and GALEX photometry
Ariel Werle, Roberto Cid Fernandes, Natalia Vale Asari +10
Stellar population studies of early-type galaxies (ETGs) based on their optical stellar continuum suggest that these are quiescent systems. However, emission lines and ultraviolet…
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.…
Spatial field reconstruction with INLA: Application to IFU galaxy data
S. González-Gaitán, R. S. de Souza, A. Krone-Martins +4
Astronomical observations of extended sources, such as cubes of integral field spectroscopy (IFS), encode auto-correlated spatial structures that cannot be optimally exploited by s…
An analysis of the composite stellar population in M32
P. Coelho, C. Mendes de Oliveira, R. Cid Fernandes
We obtained long-slit spectra of high signal-to-noise ratio of the galaxy M32 with the GMOS spectrograph at the GEMINI North telescope. We analysed the integrated spectra by means…
