Stellar populations of galaxies in the ALHAMBRA survey up to . III. The stellar content of the quiescent galaxy population during the last Gyr
L. A. Díaz-García, A. J. Cenarro, C. López-Sanjuan +27
We aim at constraining the stellar population properties of quiescent galaxies. These properties reveal how these galaxies evolved and assembled since up to the present ti…
Stellar populations of galaxies in the ALHAMBRA survey up to . II. Stellar content of quiescent galaxies within the dust-corrected stellar masscolour and the colourcolour diagrams
L. A. Díaz-García, A. J. Cenarro, C. López-Sanjuan +27
Our aim is to determine the distribution of stellar population parameters (extinction, age, metallicity, and star formation rate) of quiescent galaxies within the rest-frame stella…
The ALHAMBRA survey: 2-D analysis of the stellar populations in massive early-type galaxies at z < 0.3
I. San Roman, A. J. Cenarro, L. A. Díaz-García +29
We present a technique that permits the analysis of stellar population gradients in a relatively low cost way compared to IFU surveys analyzing a vastly larger samples as well as o…
The Gaia-ESO Survey. Mg-Al anti-correlation in iDR4 globular clusters
E. Pancino, the GES collaboration
We use Gaia-ESO Survey iDR4 data to explore the Mg-Al anti-correlation in globular clusters, that were observed as calibrators, as a demonstration of the quality of Gaia-ESO Survey…
The -ESO Survey: the inner disk intermediate-age open cluster NGC 6802
B. Tang, D. Geisler, E. Friel +43
Milky Way open clusters are very diverse in terms of age, chemical composition, and kinematic properties. Intermediate-age and old open clusters are less common, and it is even har…
The Gaia-ESO Survey: the inner disk, intermediate-age open cluster Trumpler 23
J. C. Overbeek, E. D. Friel, P. Donati +33
Context: Trumpler 23 is a moderately populated, intermediate-age open cluster within the solar circle at a Rgc ~6 kpc. It is in a crowded field very close to the Galactic plane and…
The Gaia-ESO Survey: Probes of the inner disk abundance gradient
H. R. Jacobson, E. D. Friel, L. Jilkova +41
The nature of the metallicity gradient inside the solar circle (R_GC < 8 kpc) is poorly understood, but studies of Cepheids and a small sample of open clusters suggest that it stee…
The Gaia-ESO Survey: Insights on the inner-disc evolution from open clusters
L. Magrini, S. Randich, P. Donati +37
Context. The inner disc, linking the thin disc with the bulge, has been somehow neglected in the past because of intrinsic difficulties in its study, due, e.g., to crowding and hig…
Evidence for temporal evolution in the M33 disc as traced by its star clusters
Michael A. Beasley, Izaskun San Roman, Carme Gallart +2
We present precision radial velocities and stellar population parameters for 77 star clusters in the Local Group galaxy M33. Our GTC and WHT observations sample both young, massive…
The Gaia-ESO Survey: Detailed Abundances in the Metal-poor Globular Cluster NGC 4372
I. San Roman, C. Muñoz, D. Geisler +28
We present the abundance analysis for a sample of 7 red giant branch stars in the metal-poor globular cluster NGC 4372 based on UVES spectra acquired as part of the Gaia-ESO Survey…
Testing the chemical tagging technique with open clusters
S. Blanco-Cuaresma, C. Soubiran, U. Heiter +12
