A 3D Dust Map Based on Gaia, Pan-STARRS 1 and 2MASS

Understand

We present a new three-dimensional map of dust reddening, based on Gaia parallaxes and stellar photometry from Pan-STARRS 1 and 2MASS.

• This map covers the sky north of a declination of -30 degrees, out to a distance of several kiloparsecs.
• This new map contains three major improvements over our previous work.
• First, the inclusion of Gaia parallaxes dramatically improves distance estimates to nearby stars.
