Effects of environment on sSFR profiles of late-type galaxies in the CALIFA survey
(EDP Sciences, 2019-01-15)
We explore the effects of environment on star formation in late-type galaxies by studying the dependence of the radial profiles of specific star formation rate (sSFR) on environment and the stellar mass, using a sample of ...
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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
Effect of bars on the galaxy properties
(EDP Sciences, 2016-11)
Aims. With the aim of assessing the effects of bars on disk galaxy properties, we present an analysis of different characteristics of spiral galaxies with strong bars, weak bars and without bars. Methods. Weidentified ...
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 ...
Oxygen yields as a constraint on feedback processes in galaxies
(Wiley Blackwell Publishing, Inc, 2019-09)
We study the interplay between several properties determined from optical and a combination of optical/radio measurements, such as the effective oxygen yield (yeff), the star formation efficiency, gas metallicity, depletion ...
