The population of early-type galaxies: how it evolves with time and how it differs from passive and late-type galaxies
S. Tamburri, P. Saracco, M. Longhetti +3
The aim of our analysis is twofold. On the one hand we are interested in addressing whether a sample of ETGs morphologically selected differs from a sample of passive galaxies in t…
Lower mass normalization of the stellar initial mass function for dense massive early-type galaxies at z ~ 1.4
A. Gargiulo, P. Saracco, M. Longhetti +3
This paper aims at understanding if the normalization of the stellar initial mass function (IMF) of massive early-type galaxies (ETGs) varies with cosmic time and/or with mean stel…
Spectral detection of multiple stellar populations in z~1 early-type galaxies
I. Lonoce, M. Longhetti, P. Saracco +2
We present a spectroscopic analysis based on measurements of two mainly age-dependent spectrophotometric indices in the 4000A rest frame region, i.e. H+K(CaII) and Delta4000, for a…
LBT-LUCIFER spectroscopy: kinematics of a compact early type galaxy at z\simeq1.4
Marcella Longhetti, Paolo Saracco, Adriana Gargiulo +2
We present a high signal to noise (S/N10) medium resolution (R=2000) LBT-LUCIFER spectrum of the early-type galaxy (ETG) S2F1-142 at . By means of the CaT line at $8…
Scaling relations of cluster elliptical galaxies at z~1.3. Distinguishing luminosity and structural evolution
P. Saracco, A. Casati, A. Gargiulo +10
[Abridged] We studied the size-surface brightness and the size-mass relations of a sample of 16 cluster elliptical galaxies in the mass range 10^{10}-2x10^{11} M_sun which were mor…
