Different paths, same appearance: an intermediate-age red nugget at z~0.13
F. La Barbera, F. Buitrago, I. Ferreras +1
Massive ultra-compact galaxies are commonly regarded as nearby relics of the compact quiescent population at z~2-3, and detailed studies have focused so far only on old systems in…
Reinterpreting the puzzling properties of z>6 galaxies within a variable IMF framework
Fabio Fontanot, Gabriella De Lucia, Lizhi Xie +6
Recent results form the James Webb Space Telescope (JWST) report space densities for bright and massive galaxies at z>7 that far exceed expectations of theoretical models of galaxy…
Contrasting evolutionary pathways of fast- and slow-rotating galaxies in the green valley
Shuang Zhou, Angela Iovino, Marcella Longhetti +2
We investigate the evolutionary pathways of green valley (GV) galaxies drawn from the SDSS-IV/MaNGA survey. The GV sample is divided into fast- and slow-rotating galaxies based on…
Why the Northern Hemisphere Needs a 30-40m Telescope and the Science at Stake: Shaping Galaxies and Their Stars with Stellar Population Gradients, IMF Variations and Environmental Drivers in Cluster Early-Type Galaxies
A. Vazdekis, P. Sánchez-Blázquez, A. Ferré-Mateu +23
This white paper highlights how stellar population gradients, chemical abundance patterns, stellar initial mass function (IMF) variations, and structural signatures in early-type g…
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…
