Elemental abundance ratios for the bulge of M31
F. La Barbera, A. Vazdekis, F. Matteucci +3
We present radial trends of metallicity ([Fe/H]) and abundance ratios ([X/Fe]) for several chemical elements -- including C, N, Na, and the so-called alpha-elements (O, Mg, Si, Ca,…
Puzzling radial gradients of K-band absorption features in the giant elliptical galaxy M87
F. La Barbera, A. Vazdekis, A. Pasquali +8
We present new K-band spectroscopy for the giant elliptical galaxy M87 in the Virgo cluster, taken with the LUCI spectrograph at the Large Binocular Telescope (LBT). The new data a…
TP-AGB stars and stellar population properties of a post-starburst galaxy at through optical and NIR spectroscopy with JWST
Davide Bevacqua, Paolo Saracco, Francesco La Barbera +11
We present a detailed optical and NIR spectral analysis of J-138717, a post-starburst galaxy at observed with JWST/NIRSpec, for which we derive a stellar mass of $3.5…
Chemical abundance ratios for the bulge of M31
F. La Barbera, A. Vazdekis, A. Pasquali
We present abundance ratio estimates of individual elements, namely C, N, Na, and the so-called alpha elements, Mg, O, Si, Ca, and Ti, for the bulge of M31. The analysis is based o…
A new perspective on the stellar Mass-Metallicity Relation of quiescent galaxies from the LEGA-C survey
D. Bevacqua, P. Saracco, A. Boecker +7
We investigate the stellar Mass-Metallicity Relation (MZR) using a sample of 637 quiescent galaxies with 10.4 <= log(M*/M ) < 11.7 selected from the LEGA-C survey at 0.6 <= z <= 1.…
CO radial gradients in the bulge of M31
F. La Barbera, A. Vazdekis, A. Pasquali +3
We present new H- and K-band spectroscopy for the bulge of M31, taken with the LUCI spectrograph at the Large Binocular Telescope (LBT). We studied radial trends of CO absorption f…
