Eye of the beholder: Observer reference frame bias in Hickson-like compact groups of galaxies
A. Zandivarez, E. Diaz-Gimenez, A. R. Callen
[Abridged] We investigate how the identification of Hickson-like CGs depends on the observer's reference frame, quantifying how frequently the same system would be recognised from…

Compact groups from semi-analytical models of galaxy formation -- VI: Evolution of the two first-ranked galaxies
A. Zandivarez, E. Diaz-Gimenez
[Abridged] Compact groups (CGs) of galaxies have proven to be unique environments for studying galaxy interactions. We propose a detailed analysis of the galaxy evolution to disent…

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…
