The spectral energy distributions (SEDs) of galaxies are shaped by nearly every physical
property of the system, including the star-formation history, metal content, abundance …

Fitting the spectral energy distributions (SEDs) of galaxies is an almost universally used
technique that has matured significantly in the last decade. Model predictions and fitting …

ABSTRACT I introduce some improvements to the ppxf method, which measures the stellar
and gas kinematics, star formation history (SFH) and chemical composition of galaxies. I …

Deriving the expansion history of the Universe is a major goal of modern cosmology. To
date, the most accurate measurements have been obtained with Type Ia Supernovae (SNe) …

We measure a value for the cosmic expansion of H (z)= 89±23 (stat)±44 (syst) km s− 1 Mpc−
1 at a redshift of z≃ 0.47 based on the differential age technique. This technique, also known …

Aims. We present a new library of high-resolution synthetic spectra based on the stellar
atmosphere code PHOENIX that can be used for a wide range of applications of spectral …

We present a new-generation tool to model and interpret spectral energy distributions
(SEDs) of galaxies, which incorporates in a consistent way the production of radiation and its …

Context. Gaia Data Release 3 contains astrometry and photometry results for about 1.8
billion sources based on observations collected by the European Space Agency (ESA) Gaia …

The relation between galaxy stellar mass and gas-phase metallicity is a sensitive diagnostic
of the main processes that drive galaxy evolution, namely cosmological gas inflow, metal …

We present a new model for computing the spectral evolution of stellar populations at ages
between 1× 105 and 2× 1010 yr at a resolution of 3 Å across the whole wavelength range …
