A Three-Year Multi-Wavelength Study of the Very High Energy Gamma-ray Blazar 1ES 0229+200
E. Aliu, S. Archambault, T. Arlen +83
The high-frequency-peaked BL Lacertae object 1ES 0229+200 is a relatively distant (z = 0.1396), hard-spectrum (Gamma ~ 2.5), very-high-energy-emitting (E > 100 GeV) gamma-ray blaza…
One-Class Classification: Taxonomy of Study and Review of Techniques
Shehroz S. Khan, Michael G. Madden
One-class classification (OCC) algorithms aim to build classification models when the negative class is either absent, poorly sampled or not well defined. This unique situation con…
Long-term TeV and X-ray Observations of the Gamma-ray Binary HESS J0632+057
VERITAS Collaboration, E. Aliu, S. Archambault +297
HESS J0632+057 is the only gamma-ray binary known so far whose position in the sky allows observations with ground-based observatories both in the northern and southern hemispheres…
Algebraic Morse theory and homological perturbation theory
Emil Sköldberg
We show that the main result of algebraic Morse theory can be obtained as a consequence of the perturbation lemma of Brown and Gugenheim.
VERITAS Observations of the Microquasar Cygnus X-3
S. Archambault, M. Beilicke, W. Benbow +76
We report results from TeV gamma-ray observations of the microquasar Cygnus X-3. The observations were made with the Very Energetic Radiation Imaging Telescope Array System (VERITA…
Observation of Markarian 421 in TeV gamma rays over a 14-year time span
V. A. Acciari, T. Arlen, T. Aune +73
The variability of the blazar Markarian 421 in TeV gamma rays over a 14-year time period has been explored with the Whipple 10 m telescope. It is shown that the dynamic range of it…
Multiwavelength Observations of The TeV Binary LS I +61 303 with VERITAS, Fermi-LAT and Swift-XRT During a TeV Outburst
E. Aliu, S. Archambault, B. Behera +71
We present the results of a multiwavelength observational campaign on the TeV binary system LS I +61 303 with the VERITAS telescope array (>200 GeV), Fermi-LAT (0.3-300 GeV), and S…
Long term observations of B2 1215+30 with VERITAS
VERITAS collaboration, E. Aliu, S. Archambault +82
We report on VERITAS observations of the BL Lac object B2 1215+30 between 2008 and 2012. During this period, the source was detected at very high energies (VHE; E > 100 GeV) by VER…
Periodic Optical Variability of Radio Detected Ultracool Dwarfs
Leon K. Harding, Gregg Hallinan, Richard P. Boyle +5
A fraction of very low mass stars and brown dwarfs are known to be radio active, in some cases producing periodic pulses. Extensive studies of two such objects have also revealed o…
Higher-order Reverse Automatic Differentiation with emphasis on the third-order
Robert M. Gower, Artur L. Gower
It is commonly assumed that calculating third order information is too expensive for most applications. But we show that the directional derivative of the Hessian (…
A search for enhanced very high energy gamma-ray emission from the March 2013 Crab Nebula flare
The VERITAS Collaboration, E. Aliu, S. Archambault +76
In March 2013, a flaring episode from the Crab Nebula lasting ~2 weeks was detected by the Fermi-LAT (Large Area Telescope on board the Fermi Gamma-ray Space Telescope). VERITAS pr…
Unified Models of Molecular Emission from Class 0 Protostellar Outflow Sources
J. M. C. Rawlings, M. P. Redman, P. B. Carolan
Low mass star-forming regions are more complex than the simple spherically symmetric approximation that is often assumed. We apply a more realistic infall/outflow physical model to…
Discovery of a new TeV gamma-ray source: VER J0521+211
VERITAS Collaboration, S. Archambault, T. Arlen +83
We report the detection of a new TeV gamma-ray source, VER J0521+211, based on observations made with the VERITAS imaging atmospheric Cherenkov telescope array. These observations…
Optical Observations of PSR J0205+6449 - the next optical pulsar?
P. Moran, R. P. Mignani, S. Collins +3
PSR J0205+6449 is a young ({\approx} 5400 years), Crab-like pulsar detected in radio and at X and γ-ray energies and has the third largest spin-down flux among known rotation power…
Multiwavelength observations and modeling of 1ES 1959+650 in a low flux state
VERITAS Collaboration, E. Aliu, S. Archambault +82
We report on the VERITAS observations of the high-frequency peaked BL Lac object 1ES 1959+650 in the period 2007-2011. This source is detected at TeV energies by VERITAS at 16.4 st…
Measurement-induced generation of spatial entanglement in a two-dimensional quantum walk with single-qubit coin
C. Di Franco, M. Mc Gettrick, T. Machida +1
One of the proposals for the exploitation of two-dimensional quantum walks has been the efficient generation of entanglement. Unfortunately, the technological effort required for t…
Finding Information Through Integrated Ad-Hoc Socializing in the Virtual and Physical World
Christian von der Weth, Manfred Hauswirth
Despite the services of sophisticated search engines like Google, there are a number of interesting information sources which are useful but largely inaccessible to current Web use…
DOBBS: Towards a Comprehensive Dataset to Study the Browsing Behavior of Online Users
Christian von der Weth, Manfred Hauswirth
The investigation of the browsing behavior of users provides useful information to optimize web site design, web browser design, search engines offerings, and online advertisement.…
Proper Motions in Globular Clusters using Deconvolution of HST Images
Navtej Singh, Lisa-Marie Browne, Ray Butler
A sub-sampled deconvolution technique for crowded field photometry with the HST WFPC2 instrument was proposed by Butler (2000) and applied to search for optical counterparts to pul…
Parallel Astronomical Data Processing with Python: Recipes for multicore machines
Navtej Singh, Lisa-Marie Browne, Ray Butler
High performance computing has been used in various fields of astrophysical research. But most of it is implemented on massively parallel systems (supercomputers) or graphical proc…
Influence of Preservation Temperature on the Measured Mechanical Properties of Brain Tissue
Badar Rashid, Michel Destrade, Michael Gilchrist
The large variability in experimentally measured mechanical properties of brain tissue is due to many factors including heterogeneity, anisotropy, age dependence and post-mortem ti…
Shear instability in skin tissue
Pasquale Ciarletta, Michel Destrade, Artur L. Gower
We propose two toy-models to describe, predict, and interpret the wrinkles appearing on the surface of skin when it is sheared. With the first model, we account for the lines of gr…
The Galway Astronomical Stokes Polarimeter: An All-Stokes Optical Polarimeter with Ultra-High Time Resolution
Patrick Collins, Gillian Kyne, David Lara +3
Many astronomical objects emit polarised light, which can give information both about their source mechanisms, and about (scattering) geometry in their source regions. To date (mos…
