On the accretion of a new group of galaxies onto Virgo: III. The stellar population radial gradients of dEs
Bahar Bidaran, Francesco La Barbera, Anna Pasquali +6
Using MUSE data, we investigate the radial gradients of stellar population properties (namely age, [M/H], and the abundance ratio of elements [/Fe]) for a sample of nine dwa…
BCG alignment with the Locations of Cluster Members and the Large Scale Structure out to 10 R
Rory Smith, Ho Seong Hwang, Katarina Kraljic +8
Using a sample of clusters, each with typically spectroscopically confirmed cluster members, we search for a signal of alignment between the Position Angle (PA) of…
The elemental abundances of quiescent galaxies in the LEGA-C survey: the (non-)evolution of [α/Fe] from z = 0.75 to z = 0
Davide Bevacqua, Paolo Saracco, Francesco La Barbera +6
We measure the [/Fe] abundances for 183 quiescent galaxies at z = 0.60 - 0.75 with stellar masses ranging 10.4 \leq log10 10.4 log10 (M /M) 11.6 select…
The star formation history and the nature of the mass-metallicity relation of passive galaxies at 1.0<z<1.4 from VANDELS
Paolo Saracco, Francesco La Barbera, Roberto De Propris +9
We derived stellar ages and metallicities [Z/H] for 70 passive early type galaxies (ETGs) selected from VANDELS survey over the redshift range 1.01.4 and stellar mas…
