A Synoptic Map of Halo Substructures from the Pan-STARRS1 3Ï 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…
Design Differences between the Pan-STARRS PS1 and PS2 Telescopes
Jeffrey S. Morgan, Nicholas Kaiser, Vincent Moreau +2
The PS2 telescope is the second in an array of wide-field telescopes that is being built for the Panoramic-Survey Telescope and Rapid Response System (Pan-STARRS) on Haleakala. The…
Spectroscopy of the three distant Andromedan satellites Cassiopeia III, Lacerta I, and Perseus I
Nicolas F. Martin, Kenneth C. Chambers, Michelle L. M. Collins +10
We present Keck II/DEIMOS spectroscopy of the three distant dwarf galaxies of M31 Lacerta I, Cassiopeia III, and Perseus I, recently discovered within the Pan-STARRS1 3Ïimaging su…
The Complex Structure of Stars in the Outer Galactic Disk as revealed by Pan-STARRS1
Colin T. Slater, Eric F. Bell, Edward F. Schlafly +19
We present a panoptic view of the stellar structure in the Galactic disk's outer reaches commonly known as the Monoceros Ring, based on data from Pan-STARRS1. These observations cl…
The Main-Belt Comets: The Pan-STARRS1 Perspective
Henry H. Hsieh, Larry Denneau, Richard J. Wainscoat +17
We analyze 760475 observations of 333026 main-belt objects obtained by the Pan-STARRS1 (PS1) survey telescope between 2012 May 20 and 2013 November 9, a period during which PS1 dis…
Galactic Globular and Open Cluster Fiducial Sequences in the Pan-STARRS1 Photometric System
Edouard J. Bernard, Annette M. N. Ferguson, Edward F. Schlafly +16
We present the fiducial sequences of a sample of Galactic star clusters in the five bands of the Pan-STARRS1 (PS1) photometric system (g_P1, r_P1, i_P1, z_P1, y_P1). These empirica…
Galactic Reddening in 3D from Stellar Photometry - An Improved Map
Gregory M. Green, Edward F. Schlafly, Douglas Finkbeiner +13
We present a new 3D map of interstellar dust reddening, covering three quarters of the sky (declinations greater than -30 degrees) out to a distance of several kiloparsecs. The map…
A New Faint Milky Way Satellite Discovered in the Pan-STARRS1 3 pi Survey
Benjamin P. M. Laevens, Nicolas F. Martin, Rodrigo A. Ibata +21
We present the discovery of a faint Milky Way satellite, Laevens 2/Triangulum II, found in the Panoramic Survey Telescope And Rapid Response System (Pan-STARRS 1) 3 pi imaging data…
M Dwarf Activity in the Pan-STARRS 1 Medium-Deep Survey: First Catalog and Rotation Periods
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,…
Supervoid Origin of the Cold Spot in the Cosmic Microwave Background
András Kovács, István Szapudi, Benjamin R. Granett +13
We use a WISE-2MASS-Pan-STARRS1 galaxy catalog to search for a supervoid in the direction of the Cosmic Microwave Background Cold Spot. We obtain photometric redshifts using our mu…
Serendipitous Discovery of a Thin Stellar Stream near the Galactic Bulge in the Pan-STARRS1 3Pi Survey
Edouard J. Bernard, Annette M. N. Ferguson, Edward F. Schlafly +22
We report the discovery of a thin stellar stream found in Pan-STARRS1 photometry near the Galactic bulge in the constellation of Ophiuchus. It appears as a coherent structure in th…
Lacerta I and Cassiopeia III: Two luminous and distant Andromeda satellite dwarf galaxies found in the 3Ï Pan-STARRS1 survey
Nicolas F. Martin, Colin T. Slater, Edward F. Schlafly +17
We report the discovery of two new dwarf galaxies, Lacerta I/Andromeda XXXI (Lac I/And XXXI) and Cassiopeia III/Andromeda XXXII (Cas III/And XXXII), in stacked Pan-STARRS1 r_P1- an…
Astrometric evidence for a population of dislodged AGN
Valeri V. Makarov, Julien Frouard, Ciprian T. Berghea +5
We investigate a sample of 2293 ICRF2 extragalactic radio-loud sources with accurate positions determined by VLBI, mostly active galactic nuclei (AGN) and quasars, which are cross-…
A Periodically Varying Luminous Quasar at z=2 from the Pan-STARRS1 Medium Deep Survey: A Candidate Supermassive Black Hole Binary in the Gravitational Wave-Driven Regime
Tingting Liu, Suvi Gezari, Sebastien Heinis +11
Supermassive black hole binaries (SMBHBs) should be an inevitable consequence of the hierarchical growth of massive galaxies through mergers, and the strongest sirens of gravitatio…
Detection of a Supervoid Aligned with the Cold Spot of the Cosmic Microwave Background
István Szapudi, András Kovács, Benjamin R. Granett +13
We use the WISE-2MASS infrared galaxy catalog matched with Pan-STARRS1 (PS1) galaxies to search for a supervoid in the direction of the Cosmic Microwave Background Cold Spot. Our i…
The Cold Spot in the Cosmic Microwave Background: the Shadow of a Supervoid
István Szapudi, András Kovács, Benjamin R. Granett +14
Standard inflationary hot big bang cosmology predicts small fluctuations in the Cosmic Microwave Background (CMB) with isotropic Gaussian statistics. All measurements support the s…
