Observations of galaxy isophotes, long-slit kinematics, and high-resolution photometry
suggested a possible dichotomy between two distinct classes of elliptical galaxies. But these …

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 …

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 …

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 …

The primary method for inferring the stellar mass (M*) of a galaxy is through spectral energy
distribution (SED) modeling. However, the technique rests on assumptions such as the …

Various different physical processes contribute to the star formation and stellar mass
assembly histories of galaxies. One important approach to understanding the significance of …

We present synthetic spectral energy distributions (SEDs) for single-age, single-metallicity
stellar populations (SSPs) covering the full optical spectral range at moderately high …

We present a new spectral fitting code, firefly, for deriving the stellar population properties of
stellar systems. firefly is a chi-squared minimization fitting code that fits combinations of …

Aims. We provide an easy-to-use full-spectrum fitting package and explore its applications to
(i) the determination of the stellar atmospheric parameters and (ii) the study of the history of …

We present UV-extended E-MILES stellar population synthesis models covering the spectral
range λλ 1680–50 000 Å at moderately high resolution. We employ the NGSL space-based …
