Galactic reddening in 3D from stellar photometry – an improved map
Galactic reddening in 3D from stellar photometry – an improved map
We present a new 3D map of interstellar dust reddening, covering three quarters of the sky (declinations of δ ≳ −30°) out to a distance of several kiloparsecs. The map is based on high-quality stellar photometry of 800 million stars from Pan-STARRS 1 and 2MASS. We divide the sky into …
