Accretion of galaxy groups into galaxy clusters
(Wiley Blackwell Publishing, Inc, 2020-11)
We study the role of group infall in the assembly and dynamics of galaxy clusters in ΛCDM. We select 10 clusters with virial mass M200 ∼1014 M from the cosmological hydrodynamical simulation Illustris and follow their ...
Effects of environment on stellar metallicity profiles of late-type galaxies in the CALIFA survey
(EDP Sciences, 2020-10)
Aims. We explore the effects of environment in the evolution of late-type galaxies by studying the radial profiles of light- and massweighted metallicities of galaxies in two discrete environments: field and groups. Methods. ...
Galaxies infalling into groups: Filaments versus isotropic infall
(Oxford University Press, 2015-10)
We perform a comparative analysis of the properties of galaxies infalling into groups classifying them accordingly to whether they are: Falling along filamentary structures; or they are falling isotropically. For this ...
Physically motivated fit to mass surface density profiles observed in galaxies
(IOP Publishing, 2021-11)
Polytropes have gained renewed interest because they account for several seemingly disconnected observational properties of galaxies. Here we study whether polytropes are also able to explain the stellar mass distribution ...
Nuclear Kinematics of Narrow-line Seyfert 1 Galaxies
(University of Chicago Press, 2019-03)
Here I present the main results of a kinematical study of narrow line Seyfert 1 galaxies through long slit spectroscopy.
Filaments in VIPERS: Galaxy quenching in the infalling regions of groups
(Wiley Blackwell Publishing, Inc, 2019-03)
We study the quenching of galaxies in different environments and its evolution in the redshift range 0.43 ≤ z ≤ 0.89. For this purpose, we identify galaxies inhabiting filaments, the isotropic infall region of groups, the ...
The mass-size plane of EAGLE galaxies
(EDP Sciences, 2019-08)
Context. Current observational results show that both late- and early-type galaxies follow tight mass–size planes on which physical properties such as age, velocity dispersion, and metallicity correlate with the scatter ...
Chemical abundances of Seyfert 2 AGNs, II: N2 metallicity calibration based on SDSS
(Wiley Blackwell Publishing, Inc, 2020-06)
We present a semi-empirical calibration between the metallicity (Z) of Seyfert 2 active galactic nuclei and the N2 = log([N II]λ6584/H a) emission-line intensity ratio. This calibration was derived through the [OIII]λ5007/[O ...
Early-type galaxies in the Antlia cluster: Catalogue and isophotal analysis
(Wiley Blackwell Publishing, Inc, 2018-06)
We present a statistical isophotal analysis of 138 early-type galaxies in the Antlia cluster, located at a distance of ~35 Mpc. The observational material consists of CCD images of four 36 ×36 arcmin2 fields obtained with ...
Ring galaxies in the EAGLE hydrodynamical simulations
(Wiley Blackwell Publishing, Inc, 2018-12)
We study the formation and evolution of ring galaxies in the Evolution and Assembly of GaLaxies and their Environments (EAGLE) simulations. We use the largest reference model Ref-L100N1504, a cubic cosmological volume of ...
