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…
