The fate of high-redshift massive compact galaxies
Ignacio G. de la Rosa, Francesco La Barbera, Ignacio Ferreras +4
Massive high-redshift quiescent compact galaxies (nicknamed red nuggets) have been traditionally connected to present-day elliptical galaxies, often overlooking the relationships t…
On The Nature of Fossil Galaxy Groups
F. La Barbera, R. R. de Carvalho, I. G. de la Rosa +3
We present a new sample of 25 fossil groups (FGs) at z < 0.1, along with a control sample of seventeen bright ellipticals located in non-fossil systems. Both the global properties…
Superdense massive galaxies in the Nearby Universe
Ignacio Trujillo, A. Javier Cenarro, Adriana de Lorenzo-Caceres +3
Superdense massive galaxies (r_e~1 kpc; M~10^{11} Msun) were common in the early universe (z>1.5). Within some hierarchical merging scenarios, a non-negligible fraction (1-10%) of…
A Principal Component Analysis approach to the Star Formation History of elliptical galaxies in Compact Groups
I. Ferreras, A. Pasquali, R. R. de Carvalho +2
(Abridged) Environmental differences in the stellar populations of early-type galaxies are explored using principal component analysis (PCA), focusing on differences between ellipt…
