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 …

Healthy vegetation function supports diverse biological communities and ecosystem
processes, and provides crops, forest products, forage, and countless other benefits …

This paper documents the seventeenth data release (DR17) from the Sloan Digital Sky
Surveys; the fifth and final release from the fourth phase (SDSS-IV). DR17 contains the …

The Sloan Digital Sky Surveys (SDSS) have been almost continuously observing the skies
for over 20 yr, since the project began with a first phase in 1998 (SDSS-I; York et al. 2000) …

I start by providing an updated summary of the penalized pixel-fitting (ppxf) method that is
used to extract the stellar and gas kinematics, as well as the stellar population of galaxies …

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 measurements of dust reddening using the colors of stars with spectra in the
Sloan Digital Sky Survey. We measure reddening as the difference between the measured …

Planck has mapped the microwave sky in temperature over nine frequency bands between
30 and 857 GHz and in polarization over seven frequency bands between 30 and 353 GHz …

Abstract The Radial Velocity Experiment (RAVE) is a magnitude-limited (9< I< 12)
spectroscopic survey of Galactic stars randomly selected in Earth's southern hemisphere …

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