Phonons in two-dimensional soft colloidal crystals
Ke Chen, Tim Still, Samuel Schoenholz +5
The vibrational modes of pristine and polycrystalline monolayer colloidal crystals composed of thermosensitive microgel particles are measured using video microscopy and covariance…
Abrupt Longitudinal Magnetic Field Changes and Ultraviolet Emissions Accompanying Solar Flares
Brittany Johnstone, Gordon Petrie, Jeffrey Sudol
We have used Transition Region and Coronal Explorer (TRACE) 1600 Åimages and Global Oscillation Network Group (GONG) magnetograms to compare ultraviolet (UV) emissions from the chr…
A Magnetic Confinement vs. Rotation Classification of Massive-Star Magnetospheres
V. Petit, S. P. Owocki, G. A. Wade +12
Building on results from the Magnetism in Massive Stars (MiMeS) project, this paper shows how a two-parameter classification of massive-star magnetospheres in terms of the magnetic…
Exceptional sets for Diophantine inequalities
Scott T. Parsell, Trevor D. Wooley
We apply Freeman's variant of the Davenport-Heilbronn method to investigate the exceptional set of real numbers not close to some value of a given real diagonal form at an integral…
Characterization of tropical hemispaces by (P,R)-decompositions
Ricardo D. Katz, Viorel Nitica, Sergei Sergeev
We consider tropical hemispaces, defined as tropically convex sets whose complements are also tropically convex, and tropical semispaces, defined as maximal tropically convex sets…
Discovery of a magnetic field in the rapidly-rotating O-type secondary of the colliding-wind binary HD 47129 (Plaskett's star)
J. H. Grunhut, G. A. Wade, M. Leutenegger +14
We report the detection of a strong, organized magnetic field in the secondary component of the massive O8III/I+O7.5V/III double-lined spectroscopic binary system HD 47129 (Plasket…
The Atacama Cosmology Telescope: Data Characterization and Map Making
Rolando Dünner, Matthew Hasselfield, Tobias A. Marriage +71
We present a description of the data reduction and mapmaking pipeline used for the 2008 observing season of the Atacama Cosmology Telescope (ACT). The data presented here at 148 GH…
Refining genetically inferred relationships using treelet covariance smoothing
Andrew Crossett, Ann B. Lee, Lambertus Klei +2
Recent technological advances coupled with large sample sets have uncovered many factors underlying the genetic basis of traits and the predisposition to complex disease, but much…
Discovery of an Unusually Red L-type Brown Dwarf
John E. Gizis, Jacqueline K. Faherty, Michael C. Liu +6
We report the discovery of an unusually red brown dwarf found in a search for high proper motion objects using WISE and 2MASS data. WISEP J004701.06+680352.1 is moving at 0.44$ arc…
NGC 1624-2: A slowly rotating, X-ray luminous Of?cp star with an extraordinarily strong magnetic field
G. A. Wade, J. Maíz Apellániz, F. Martins +16
This paper presents a first observational investigation of the faint Of?cp star NGC 1624-2, yielding important new constraints on its spectral and physical characteristics, rotatio…
Near-optimal mean value estimates for multidimensional Weyl sums
Scott T. Parsell, Sean M. Prendiville, Trevor D. Wooley
We obtain sharp estimates for multidimensional generalisations of Vinogradov's mean value theorem for arbitrary translation-dilation invariant systems, achieving constraints on the…
Magnetometry of a sample of massive stars in Carina
Y. Naze, S. Bagnulo, V. Petit +4
X-ray surveys of the Carina nebula have revealed a few hard and luminous sources associated with early-type stars. Such unusual characteristics for the high-energy emission may be…
The Atacama Cosmology Telescope: Dynamical Masses and Scaling Relations for a Sample of Massive Sunyaev-Zel'dovich Effect Selected Galaxy Clusters
Cristóbal Sifón, Felipe Menanteau, Matthew Hasselfield +33
We present the first dynamical mass estimates and scaling relations for a sample of Sunyaev-Zel'dovich effect (SZE) selected galaxy clusters. The sample consists of 16 massive clus…
High-Mass, Four-Planet Models for HR 8799: Constraining the Orbital Inclination and Age of the System
Jeffrey J. Sudol, Nader Haghighipour
Debates regarding the age and inclination of the planetary system orbiting HR 8799, and the release of additional astrometric data following the discovery of the fourth planet prom…
