Semiresolved Stellar Populations as Distance Indicators
Ignacio Martín-Navarro, Patricia Iglesias Navarro, Francesco La Barbera +13
Galaxy distances are central to our understanding of the Universe. Despite the success of existing approaches, independent and complementary methods remain valuable for testing sys…
Probing IMF Variations in High-Redshift Early-Type Galaxies with SHARP
F. La Barbera, G. De Lucia, F. Ditrani +9
The stellar initial mass function (IMF), which describes the distribution of stellar masses at birth, is a fundamental ingredient in shaping galaxy evolution. Recent observations i…
SHARP -- A spectrograph proposal to fully exploit ELT capabilities and look beyond JWST
P. Saracco, P. Conconi, C. Arcidiacono +47
The Extremely Large Telescopes (ELTs), with their large apertures and cutting-edge Multi-Conjugate Adaptive Optics (MCAO) systems, promise to deliver data that is both sharper and…
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…
FASTAR -- II. Semi-resolved evolutionary stellar population models
Ignacio Martín-Navarro, Alexandre Vazdekis, Luis Peralta de Arriba +12
Standard evolutionary synthesis models rely on the assumption of a fully sampled stellar initial mass function (IMF). Under this assumption, the age, chemical composition, and IMF…
FASTAR -- I. Continuous and differentiable evolutionary stellar population models
Ignacio Martín-Navarro, Alexandre Vazdekis, Luis Peralta de Arriba +11
The development of evolutionary stellar population models is central to interpreting observations of galaxies in terms of astrophysical quantities. Stellar population models must t…
