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…
Accelerated quenching and chemical enhancement of massive galaxies in a gas-rich halo
Pablo G. Pérez-González, Francesco D`Eugenio, Bruno RodrÃguez del Pino +18
Stars in galaxies form when baryons radiatively cool down and fall into gravitational wells whose mass is dominated by dark matter. Eventually, star formation quenches as gas is de…
