Assessing the reliability of Friends-of-Friends groups on the future Javalambre Physics of the Accelerating Universe Astrophysical Survey
A. Zandivarez, E. Díaz-Giménez, C. Mendes de Oliveira +6
We have performed a detailed analysis of the ability of the friends-of-friends algorithm in identifying real galaxy systems in deep surveys such as the future Javalambre Physics of…
Compact Groups of Galaxies selected by stellar mass: The 2MASS Compact Group Catalogue
E. Diaz-Gimenez, G. A. Mamon, M. Pacheco +2
We present a photometric catalogue of compact groups of galaxies (p2MCGs) automatically extracted from the 2MASS extended source catalogue. A total of 262 p2MCGs are identified, fo…
Fossil Groups in the Millennium Simulation: Their environment and its evolution
Eugenia Diaz-Gimenez, Ariel Zandivarez, Robert Proctor +3
Fossil systems are defined to be X-ray bright galaxy groups with a 2-magnitude difference between their two brightest galaxies within half the projected virial radius,and represent…
The nature of compact groups of galaxies from cosmological simulations
G. A. Mamon, E. Diaz-Gimenez
The nature of compact groups (CGs) of galaxies, apparently so dense that the galaxies often overlap, is still a subject of debate: Are CGs roughly as dense in 3D as they appear in…
