Chemical abundances of Seyfert 2 AGNs – IV. Composite models calculated by photoionization + shocks
(Oxford University Press, 2021-02)
We build detailed composite models of photoionization and shock ionization based on the SUMA code to reproduce emission lines emitted from the Narrow Line Regions (NLR) of Seyfert 2 nuclei. The aim of this work is to ...
Stellar kinematics across the Hubble sequence in the CALIFA survey: General properties and aperture corrections
(EDP Sciences, 2017-01)
We present the stellar kinematic maps of a large sample of galaxies from the integral-field spectroscopic survey CALIFA. The sample comprises 300 galaxies displaying a wide range of morphologies across the Hubble sequence, ...
The evolution of the metallicity gradient and the star formation efficiency in disc galaxies
(Wiley Blackwell Publishing, Inc, 2017-12)
We study the oxygen abundance profiles of the gas-phase components in hydrodynamical simulations of pre-prepared disc galaxies including major mergers, close encounters and isolated configurations. We analyse the evolution ...
Yule-Simpson's paradox in galactic archaeology
(Wiley Blackwell Publishing, Inc, 2019-05)
Simpson's paradox, or Yule-Simpson effect, arises when a trend appears in different subsets of data but disappears or reverses when these subsets are combined. We describe here seven cases of this phenomenon for chemo-kinematical ...
The DIANOGA simulations of galaxy clusters: Characterising star formation in protoclusters
(EDP Sciences, 2020-10)
We studied the star formation rate (SFR) in cosmological hydrodynamical simulations of galaxy (proto-)clusters in the redshift range 0 < z < 4, comparing them to recent observational studies; we also investigated the effect ...
Gas accretion in Milky Way-like galaxies: Temporal and radial dependencies
(Wiley Blackwell Publishing, Inc, 2019-01)
One of the fundamental assumptions of chemical evolution models (CEMs) of the Milky Way (MW) and other spirals is that higher gas accretion rates are expected in the past, and in the inner regions of the Galaxy. This leads ...
Size matters: Abundance matching, galaxy sizes, and the Tully-Fisher relation in EAGLE
(Wiley Blackwell Publishing, Inc, 2017-02)
The Tully-Fisher relation (TFR) links the stellar mass of a disc galaxy, Mstr, to its rotation speed: it is well approximated by a power law, shows little scatter, and evolves weakly with redshift. The relation has been ...
Star Formation in the Local Universe from the CALIFA Sample. II. Activation and Quenching Mechanisms in Bulges, Bars, and Disks
(IOP Publishing, 2017-10)
We estimate the current extinction-corrected Hα star formation rate (SFR) of the different morphological components that shape galaxies (bulges, bars, and disks). We use a multicomponent photometric decomposition based on ...
Effects of mergers on non-parametric morphologies
(Cambridge University Press, 2017-06)
We study the effects of mergers on non-parametric morphologies of galaxies. We compute the Gini index, M20, asymmetry and concentration statistics for z = 0 galaxies in the Illustris simulation and compare non-parametric ...
Dark matter response to galaxy assembly history
(EDP Sciences, 2019-02)
Aims. It is well known that the presence of baryons affects the dark matter host haloes. Exploring the galaxy assembly history together with the dark matter haloes properties through time can provide a way to measure these ...
