Systematic variations of central mass density slopes in early-type galaxies
C. Tortora, F. La Barbera, N. R. Napolitano +3
We study the total density distribution in the central regions (~ 1 effective radius, ) of early-type galaxies (ETGs), using data from SPIDER and . Our analysi…
SPIDER X - Environmental effects in central and satellite early-type galaxies through the stellar fossil record
F. La Barbera, A. Pasquali, I. Ferreras +3
A detailed analysis of how environment affects the star formation history of early-type galaxies (ETGs) is undertaken via high signal to noise ratio stacked spectra obtained from a…
The stellar initial mass function at 0.9<z<1.5
I. Martín-Navarro, P. G. Pérez-González, I. Trujillo +12
We explore the stellar initial mass function (IMF) of a sample of 49 massive quiescent galaxies (MQGs) at 0.9z1.5. We base our analysis on intermediate resolution spectro-pho…
Radial variations in the stellar initial mass function of early-type galaxies
Ignacio Martín-Navarro, Francesco La Barbera, Alexandre Vazdekis +2
The hypothesis of a universal initial mass function (IMF) -- motivated by observations in nearby stellar systems -- has been recently challenged by the discovery of a systematic va…
Higher prevalence of X-ray selected AGN in intermediate age galaxies up to z~1
Antonio Hernán-Caballero, Almudena Alonso-Herrero, Pablo G. Pérez-González +9
We analyse the stellar populations in the host galaxies of 53 X-ray selected optically dull active galactic nuclei (AGN) at 0.34<z<1.07 with ultra-deep (m=26.5) optical medium-band…
A panchromatic analysis of starburst galaxy M82: Probing the dust properties
S. Hutton, I. Ferreras, K. Wu +5
(Abridged) We combine NUV, optical and IR imaging of the nearby starburst galaxy M82 to explore the properties of the dust both in the interstellar medium of the galaxy and the dus…
