Untangling Stellar Components of Galaxies: Evaluation of Dynamical Decomposition Methods in Simulated Galaxies with GalaxyChop
Valeria A. Cristiani, Mario G. Abadi, Antonela Taverna +3
Galaxy formation is intrinsically connected to the distinct evolutionary processes of disk and spheroidal systems, which are the fundamental stellar components of galaxies. Underst…
Compact groups of galaxies in GAMA -- Probing the densest minor systems at intermediate redshifts
A. Zandivarez, E. Diaz-Gimenez, A. Taverna +2
[Abridged] Over the years, several compact group catalogues have been built using different methods, but most of them are not deep enough to go beyond the very local universe with…
Structure and large scale environment of galaxy pairs in the S-PLUS DR4
M. C. Cerdosino, A. L. O'Mill, F. Rodriguez +8
In this paper, we use photometric data from the S-PLUS DR4 survey to identify isolated galaxy pairs and analyse their characteristics and properties. Our results align with previou…
Compact groups from semi-analytical models of galaxy formation -- V: their assembly channels as a function of the environment
A. Taverna, E. Diaz-Gimenez, A. Zandivarez +2
We delved into the assembly pathways and environments of compact groups (CGs) of galaxies using mock catalogues generated from semi-analytical models (SAMs) on the Millennium simul…
Compact groups from semi-analytical models of galaxy formation -- IV: effect of group assembly on the evolution of their galaxies
Ariel Zandivarez, Eugenia Diaz-Gimenez, Antonela Taverna +1
Using over 3000 compact groups (CGs) of galaxies extracted from mock catalogues built from semi-analytical models of galaxy formation (SAMs), we study whether the CG assembly chann…
Hickson-like compact groups inhabiting different environments
A. Taverna, J. M. Salerno, I. V. Daza-Perilla +4
Although Compact Groups of galaxies (CGs) have been envisioned as isolated extremely dense structures in the Universe, it is accepted today that many of them could be not as isolat…
The influence of Hickson-like compact group environment on galaxy luminosities
Ariel Zandivarez, Eugenia Diaz-Gimenez, Antonela Taverna
Compact groups of galaxies are devised as extreme environments where interactions may drive galaxy evolution. In this work, we analysed whether the luminosities of galaxies inhabit…
Galaxy clustering in the VVV Near-IR Galaxy Catalogue
Mario Soto, Mario A. Sgró, Laura D. Baravalle +7
Mapping galaxies at low Galactic latitudes and determining their clustering status are fundamental steps in defining the large-scale structure in the nearby Universe. The VVV Near-…
Compact groups from semi-analytical models of galaxy formation -- III: purity and completeness of Hickson-like catalogues
Antonela Taverna, Eugenia Diaz-Gimenez, Ariel Zandivarez +1
Many catalogues of isolated compact groups of galaxies (CGs) have been extracted using Hickson's criteria to identify isolated, dense systems of galaxies, with at least three or fo…
Dust evolution in zoom-in cosmological simulations of galaxy formation
Gian Luigi Granato, Cinthia Ragone-Figueroa, Antonela Taverna +6
We present cosmological zoom-in hydro-dynamical simulations for the formation of disc galaxies, implementing dust evolution and dust promoted cooling of hot gas. We couple an impro…
Compact groups from semi-analytical models of galaxy formation -- I: a comparative study of frequency and nature
Eugenia Diaz-Gimenez, Antonela Taverna, Ariel Zandivarez +1
Compact groups (CGs) of galaxies are defined as isolated and dense galaxy systems that appear to be a unique site of multiple galaxy interactions. Semi-analytical models of galaxy…
Improving Hickson-like compact group finders in redshift surveys: an implementation in the SDSS
Eugenia Diaz-Gimenez, Ariel Zandivarez, Antonela Taverna
In this work we present an algorithm to identify compact groups (CGs) that closely follows Hickson's original aim and that improves the completeness of the samples of compact group…
On the properties of compact groups identified in different photometric bands
Antonela Taverna, Eugenia Diaz-Gimenez, Ariel Zandivarez +2
Historically, compact group catalogues vary not only in their identification algorithms and selection functions, but also in their photometric bands. Differences between compact gr…
