Massive elliptical galaxies : From cores to haloes
Chris Lintott, Ignacio Ferreras, Ofer Lahav
In the context of recent observational results that show massive ellipticals were in place at high redshifts, we reassess the status of monolithic collapse in a LCDM universe. Usin…
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…
GOODS, UDF, and the evolution of early-type galaxies
I. Ferreras, T. Lisker, A. Pasquali +3
The HST/ACS images of GOODS-South have been used to select a sample of early-type galaxies, based on morphology and on the Kormendy relation. The classification scheme does not use…
Double barred galaxies at intermediate redshifts: A feasibility study
Thorsten Lisker, Victor P. Debattista, Ignacio Ferreras +1
Despite the increasing number of studies of barred galaxies at intermediate and high redshifts, double-barred (S2B) systems have only been identified in the nearby (z<0.04) univers…
Hot Cores : Probes of High-Redshift Galaxies
C. J. Lintott, S. Viti, D. A. Williams +2
The very high rates of second generation star formation detected and inferred in high redshift objects should be accompanied by intense millimetre-wave emission from hot core molec…
The Structure and Star Formation History of Early-Type Galaxies in the UDF/GRAPES Survey
A. Pasquali, I. Ferreras, N. Panagia +9
We present a two-pronged approach to the formation of early-type galaxies, using a sample of 18 galaxies at 0.5 < z < 1 from the HST/ACS Ultra Deep Field and GRAPES surveys: 1) We…
