The evolution of brown dwarfs from L to T spectral types is one of the least understood aspects of the ultracool population, partly for lack of a large, well-defined, and well-char…
A Quasar Discovered at redshift 6.6 from Pan-STARRS1
Ji-Jia Tang, Tomotsugu Goto, Youichi Ohyama +11
Luminous high-redshift quasars can be used to probe of the intergalactic medium (IGM) in the early universe because their UV light is absorbed by the neutral hydrogen along the lin…

Pan-STARRS Photometric and Astrometric Calibration
Eugene. A. Magnier, Edward. F. Schlafly, Douglas P. Finkbeiner +18
We present the details of the photometric and astrometric calibration of the Pan-STARRS1 Survey. The photometric goals were to reduce the systematic effects introduced by the…

Eugene A. Magnier, K. C. Chambers, H. A. Flewelling +14
The Pan-STARRS Data Processing System is responsible for the steps needed to downloaded, archive, and process all images obtained by the Pan-STARRS telescopes, including real-time…
Measuring the Properties of Dark Energy with Photometrically Classified Pan-STARRS Supernovae. I. Systematic Uncertainty from Core-Collapse Supernova Contamination
D. O. Jones, D. M. Scolnic, A. G. Riess +18
The Pan-STARRS (PS1) Medium Deep Survey discovered over 5,000 likely supernovae (SNe) but obtained spectral classifications for just 10% of its SN candidates. We measured spectrosc…
Dust in three dimensions in the Galactic Plane
R. J. Hanson, C. A. L. Bailer-Jones, W. S. Burgett +6
We present three dimensional maps in monochromatic extinction and the extinction parameter within a few degrees of the Galactic plane. These are inferred using ph…
Superluminous supernova 2015bn in the nebular phase: evidence for the engine-powered explosion of a stripped massive star
M. Nicholl, E. Berger, R. Margutti +25
We present nebular-phase imaging and spectroscopy for the hydrogen-poor superluminous supernova SN 2015bn, at redshift z=0.1136, spanning +250-400 d after maximum light. The light…
A Systematic Search for Periodically Varying Quasars in Pan-STARRS1: An Extended Baseline Test in Medium Deep Survey Field MD09
T. Liu, S. Gezari, W. Burgett +10
We present a systematic search for periodically varying quasars and supermassive black hole binary (SMBHB) candidates in the Pan-STARRS1 (PS1) Medium Deep Survey's MD09 field. From…
A Synoptic Map of Halo Substructures from the Pan-STARRS1 3π Survey
Edouard J. Bernard, Annette M. N. Ferguson, Edward F. Schlafly +18
We present a panoramic map of the entire Milky Way halo north of dec~-30 degrees (~30,000 deg^2), constructed by applying the matched-filter technique to the Pan-STARRS1 3Pi Survey…
The Pan-STARRS1 distant z>5.6 quasar survey: more than 100 quasars within the first Gyr of the universe
E. Bañados, B. P. Venemans, R. Decarli +33
Luminous quasars at z>5.6 can be studied in detail with the current generation of telescopes and provide us with unique information on the first gigayear of the universe. Thus far…

Erin Kado-Fong, Peter K. G. Williams, Andrew W. Mann +9
We report on an ongoing project to investigate activity in the M dwarf stellar population observed by the Pan-STARRS 1 Medium Deep Survey (PS1-MDS). Using a custom-built pipeline,…
