Niall R. Deacon,Michael C. Liu,Eugene A. Magnier,Brendan P. Bowler,Bertrand Goldman,Joshua Redstone,William S. Burgett,K. C. Chambers,H. Flewelling,Nick Kaiser,Robert H. Lupton,John Morgan,Paul A. Price,W. Sweeney,John L. Tonry,Richard J. Wainscoat,Christopher Waters +16 more
TL;DR: In this paper, Pan-STARRS 1 optical survey telescope (PS1) data were combined with the Two Micron All Sky Survey (2MASS) to conduct a proper motion search for nearby T dwarfs, using optical+near-IR colors to select objects for spectroscopic follow-up.

PAndromeda—FIRST RESULTS FROM THE HIGH-CADENCE MONITORING OF M31 WITH Pan-STARRS 1
Chien-Hsiu Lee,Arno Riffeser,J. Koppenhoefer,Stella Seitz,Ralf Bender,Ulrich Hopp,Claus Gössl,Claus Gössl,Roberto P. Saglia,Jan Snigula,W. E. Sweeney,W. S. Burgett,K. C. Chambers,Tommy Grav,J. N. Heasley,Klaus-Werner Hodapp,Nick Kaiser,Eugene A. Magnier,John Morgan,Paul A. Price,Christopher W. Stubbs,John L. Tonry,Richard J. Wainscoat +22 more
TL;DR: The Pan-STARRS 1 (PS1) survey of M31 (PAndromeda) is designed to identify gravitational microlensing events, caused by bulge and disk stars (self-lensing) and by compact matter in the halos of M 31 and the Milky Way (halo lensing or lensing by massive compact halo objects).
Journal ArticleDOI
Three-dimensional Dust Mapping Reveals that Orion Forms Part of a Large Ring of Dust
Edward F. Schlafly,Gregory M. Green,D. P. Finkbeiner,Hans-Walter Rix,William S. Burgett,K. C. Chambers,Peter W. Draper,Nick Kaiser,Nicolas F. Martin,Nicolas F. Martin,Nigel Metcalfe,John Morgan,Paul A. Price,John L. Tonry,Richard J. Wainscoat,Christopher Waters +15 more
TL;DR: The Orion Molecular Complex is the nearest site of ongoing high-mass star formation, making it one of the most extensively studied molecular complexes in the Galaxy as mentioned in this paper, and a new technique for mapping the three-dimensional distribution of dust in the galaxy using Pan-STARRS1 photometry was developed.
