PAndAS in the mist: The stellar and gaseous mass within the halos of M31 and M33
Geraint F. Lewis, Robert Braun, Alan W. McConnachie +12
Large scale surveys of the prominent members of the Local Group have provided compelling evidence for the hierarchical formation of massive galaxies, revealing a wealth of substruc…
A high-resolution spectropolarimetric survey of Herbig Ae/Be stars - II. Rotation
E. Alecian, G. A. Wade, C. Catala +5
We report the analysis of the rotational properties of our sample of Herbig Ae/Be (HAeBe) and related stars for which we have obtained high-resolution spectropolarimetric observati…
A high-resolution spectropolarimetric survey of Herbig Ae/Be stars - I. Observations and measurements
E. Alecian, G. A. Wade, C. Catala +7
This is the first in a series of papers in which we describe and report the analysis of a large survey of Herbig Ae/Be stars in circular spectropolarimetry. Using the ESPaDOnS and…
Radon backgrounds in the DEAP-1 liquid-argon-based Dark Matter detector
P. -A. Amaudruz, M. Batygov, B. Beltran +49
The DEAP-1 \SI{7}{kg} single phase liquid argon scintillation detector was operated underground at SNOLAB in order to test the techniques and measure the backgrounds inherent to si…
Observable Vortex Properties in Finite Temperature Bose Gases
A. J. Allen, E. Zaremba, C. F. Barenghi +1
We study the dynamics of vortices in finite temperature atomic Bose-Einstein condensates, focussing on decay rates, precession frequencies and core brightness, motivated by a recen…
Measuring the Abundance of sub-kilometer sized Kuiper Belt Objects using Stellar Occultations
Hilke E. Schlichting, Eran O. Ofek, Re'em Sari +6
We present here the analysis of about 19,500 new star hours of low ecliptic latitude observations (|b| < 20 deg) obtained by the Hubble Space Telescope's FGS over a time span of mo…
Presymplectic high order maximum principle
M. Barbero-Liñán, M. C. Muñoz-Lecanda
Pontryagin's Maximum Principle is an outstanding result for solving optimal control problems by means of optimizing a specific function on some particular variables, the so called…
Feedback-controlled electromigration for the fabrication of point contacts
J. M. Campbell, R. G. Knobel
Lithographically fabricated point contacts serve as important examples of mesoscopic conductors, as electrodes for molecular electronics, and as ultra-sensitive transducers for mec…
Free resolutions of orbit closures for the representations associated to gradings on Lie algebras of type , and
Federico Galetto
The irreducible representations of complex semisimple algebraic groups with finitely many orbits are parametrized by graded simple Lie algebras. For the exceptional Lie algebras, K…
Real Second Order Freeness and Haar Orthogonal Matrices
James A. Mingo, Mihai Popa
We demonstrate the asymptotic real second order freeness of Haar distributed orthogonal matrices and an independent ensemble of random matrices. Our main result states that if we h…
A Possible Divot in the Size Distribution of the Kuiper Belt's Scattering Objects
C. Shankman, B. Gladman, N. Kaib +2
Via joint analysis of a calibrated telescopic survey, which found scattering Kuiper Belt objects, and models of their expected orbital distribution, we measure the form of the scat…
Phonon-mediated population inversion in a semiconductor quantum-dot cavity system
S. Hughes, H. J. Carmichael
We investigate pump-induced exciton inversion in a quantum-dot cavity system with continuous wave drive. Using a polaron-based master equation, we demonstrate excited-state populat…
The Sagittarius Stream and Halo Triaxiality
N. Deg, Lawrence Widrow
We present a mass model for the Milky Way, which is fit to observations of the Sagittarius stream together with constraints derived from a wide range of photometric and kinematic d…
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…
Acrylic purification and coatings
Marcin Kuźniak
Radon (Rn) and its decay daughters are a well-known source of background in direct WIMP detection experiments, as either a Rn decay daughter or an alpha particle emitted from a thi…
Difference of Normals as a Multi-Scale Operator in Unorganized Point Clouds
Yani Ioannou, Babak Taati, Robin Harrap +1
A novel multi-scale operator for unorganized 3D point clouds is introduced. The Difference of Normals (DoN) provides a computationally efficient, multi-scale approach to processing…
The Effect of Hybrid Photovoltaic Thermal Device Operating Conditions on Intrinsic Layer Thickness Optimization of Hydrogenated Amorphous Silicon Solar Cells
M. J. M Pathak, K. Girotra, S. J. Harrison +1
Historically, the design of hybrid solar photovoltaic thermal (PVT) systems has focused on cooling crystalline silicon (c-Si)-based photovoltaic (PV) devices to avoid temperature-r…
Investigating the spectroscopic, magnetic and circumstellar variability of the O9 subgiant star HD 57682
J. H. Grunhut, G. A. Wade, J. O. Sundqvist +13
The O9IV star HD 57682, discovered to be magnetic within the context of the MiMeS survey in 2009, is one of only eight convincingly detected magnetic O-type stars. Among this selec…
Phonon-Assisted Incoherent Excitation of a Quantum Dot and its Emission Properties
S. Weiler, A. Ulhaq, C. Roy +5
We present a detailed study of a phonon-assisted incoherent excitation mechanism of single quantum dots. A spectrally-detuned laser couples to a quantum dot transition by mediation…
Persistent currents in a bosonic mixture in the ring geometry
