Comparing galaxy populations in compact and loose groups of galaxies: II. Brightest group galaxies
(EDP Sciences, 2013-08)
Aims: The properties of the brightest galaxies (BCGs) are studied in both compact and loose groups of galaxies in order to better understand the physical mechanisms influencing galaxy evolution in different environments. ...
The evolution of the mass-metallicity relation in SDSS galaxies uncovered by astropaleontology
(WILEY-BLACKWELL PUBLISHING, INC, 2009)
We have obtained the mass-metallicity (M-Z) relation at different lookback times for the same set of galaxies from the Sloan Digital Sky Survey, using the stellar metallicities estimated with our spectral synthesis code ...
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 ...
From formation to quenching: The role of overdensities in high-redshift galaxy evolution
(Universidad de Concepción, 2024)
This study investigates the evolution of galaxies within 13 overdensities at redshifts 3 < z < 4, providing critical insights into galaxy formation and evolution in dense environments. Key findings include the observation ...
The extended law of star formation: the combined role of gas and stars
(Oxford University Pres, 2017)
We present a model for the origin of the extended law of star formation in which the surface density of star formation (Sigma(SFR)) depends not only on the local surface density of the gas (Sigma(g)) but also on the stellar ...
