FASTAR -- II. Semi-resolved evolutionary stellar population models
Ignacio MartÃn-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 MartÃn-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…
Tidal pre-conditioning and ram-pressure stripping in NGC 1427A. Deep VLT/MUSE spectroscopy and FUV-to-radio observations trace a Fornax Cluster dwarf in transformation
J. P. Carvajal, T. H. Puzia, M. Blaña +11
The early environmental transformation of low-mass cluster galaxies from gas-rich to gas-poor remains poorly constrained, partly because clear, phase-resolved observations are rare…
The complex history of NGC 1427A revealed by its star clusters and star formation history
Katja Fahrion, Michael Hilker, Avinash Chaturvedi +2
Star-forming low-mass galaxies in the dense environments of galaxy clusters provide opportunities to study how environmental effects such as ram-pressure stripping, tidal interacti…
Extragalactic archaeology through high-resolution integrated-light spectroscopy of globular clusters
M. A. Beasley, K. Fahrion, A. Gvozdenko +1
We propose to radically expand the use of extragalactic globular clusters as tools for extragalactic archaeology. We propose a large-scale spectroscopic facility to obtain high spe…
Distance measurements from the internal dynamics of globular clusters: Application to the Sombrero galaxy (M104)
Katja Fahrion, Michael A. Beasley, Anastasia Gvozdenko +7
Globular clusters (GCs) are dense star clusters found in all massive galaxies. Recent work has established that they follow a tight relation between their internal stellar velocity…
