Chemical hints of Population III stars from silicon abundances in massive galaxies
E. Eftekhari, A. Ferré-Mateu, A. Vazdekis +4
The formation of massive galaxies remains a fundamental question in astrophysics, with recent JWST observations suggesting that intense star formation occurred earlier than previou…
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…
Extragalactic globular cluster near-infrared spectroscopy: II. The stellar population synthesis model zero-point problem extends to the near-infrared
E. Eftekhari, A. Vazdekis, R. Riffel +5
Many recent studies have pointed out significant discrepancies between observations and models of stellar populations in the near-infrared (NIR). With current and future observing…
Extragalactic globular cluster near-infrared spectroscopy: I. Integrated near-infrared spectra of Centaurus A/NGC 5128
L. G. Dahmer-Hahn, A. L. Chies-Santos, E. Eftekhari +6
One way to constrain the evolutionary histories of galaxies is to analyse their stellar populations. In the local Universe, our understanding of the stellar population properties o…
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…
