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…
Compact groups from semi-analytical models of galaxy formation -- II: Different assembly channels
Eugenia Diaz-Gimenez, Ariel Zandivarez, Gary Mamon
We study the formation of over 6000 compact groups (CGs) of galaxies identified in mock redshift-space galaxy catalogues built from semi-analytical models of galaxy formation (SAMs…
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…
