Morphology across cosmic time: assessing the evolution and interplay of disk and bulge-dominated galaxies in the CANDELS survey
Vitor M. Sampaio, Igor Kolesnikov, Reinaldo R. de Carvalho +2
We investigate the redshift evolution of disk and bulge-dominated galaxies using a mass-complete sample of 14,000 galaxies from the CANDELS survey, selected with $H_{\rm mag}…
Galaxy Morphology in CANDELS: Addressing Evolutionary Changes Across with Hybrid Classification Approach
I. Kolesnikov, V. M. Sampaio, R. R. de Carvalho +1
Morphological classification of galaxies becomes increasingly challenging with redshift. We apply a hybrid supervised-unsupervised method to classify galaxies in the…
Probing the major driver of stellar population properties over sub-galaxy scales with SDSS MaNGA IFU spectroscopy
Ignacio Ferreras, Marina Trevisan, Ofer Lahav +2
Thanks to Integral Field Unit survey data it is possible to explore in detail the link between the formation of the stellar content in galaxies and the drivers of evolution. Tradit…
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…
IMF radial gradients in most massive early-type galaxies
F. La Barbera, A. Vazdekis, I. Ferreras +8
Using new long-slit spectroscopy obtained with X-Shooter at ESO-VLT, we study, for the first time, radial gradients of optical and Near-Infrared IMF-sensitive features in a represe…
A Principal Component Analysis approach to the Star Formation History of elliptical galaxies in Compact Groups
I. Ferreras, A. Pasquali, R. R. de Carvalho +2
(Abridged) Environmental differences in the stellar populations of early-type galaxies are explored using principal component analysis (PCA), focusing on differences between ellipt…
