Discovery of very high energy gamma rays from PKS 1424+240 and multiwavelength constraints on its redshift
The VERITAS Collaboration, V. A. Acciari, The Fermi Collaboration +4
We report the first detection of very-high-energy (VHE) gamma-ray emission above 140 GeV from PKS 1424+240, a BL Lac object with an unknown redshift. The photon spectrum above 140…
Bistability of Anderson localized states in nonlinear random media
I. V. Shadrivov, K. Y. Bliokh, Y. P. Bliokh +2
We study wave transmission through one-dimensional random nonlinear structures and predict a novel effect resulting from an interplay of nonlinearity and disorder. We reveal that,…
Free Bosonic Vertex Operator Algebras on Genus Two Riemann Surfaces I
Geoffrey Mason, Michael P. Tuite
We define the partition and -point functions for a vertex operator algebra on a genus two Riemann surface formed by sewing two tori together. We obtain closed formulas for the g…
Detection of Extended VHE Gamma Ray Emission from G106.3+2.7 with VERITAS
VERITAS Collaboration, V. A. Acciari, E. Aliu +80
We report the detection of very-high-energy (VHE) gamma-ray emission from supernova remnant (SNR) G106.3+2.7. Observations performed in 2008 with the VERITAS atmospheric Cherenkov…
Noncommutative Root Space Witt, Ricci Flow, and Poisson Bracket Continual Lie Algebras
Alexander Zuevsky
We introduce new examples of mappings defining noncommutative root space generalizations for the Witt, Ricci flow, and Poisson bracket continual Lie algebras.
A connection between star formation activity and cosmic rays in the starburst galaxy M 82
V. A. Acciari, E. Aliu, T. Arlen +89
Although Galactic cosmic rays (protons and nuclei) are widely believed to be dominantly accelerated by the winds and supernovae of massive stars, definitive evidence of this origin…
VERITAS Upper Limit on the VHE Emission from the Radio Galaxy NGC 1275
VERITAS Collaboration, V. A. Acciari, E. Aliu +88
The recent detection by the Fermi gamma-ray space telescope of high-energy gamma-rays from the radio galaxy NGC 1275 makes the observation of the very high energy (VHE: E > 100 GeV…
Multiwavelength observations of a TeV-Flare from W Comae
VERITAS collaboration, V. A. Acciari, E. Aliu +167
We report results from an intensive multiwavelength campaign on the intermediate-frequency-peaked BL Lacertae object W Com (z=0.102) during a strong outburst of very high energy ga…
A General Catalogue of Molecular Hydrogen Emission-Line Objects (MHOs) in Outflows from Young Stars
Christopher J. Davis, Ryan Gell, Tigran Khanzadyan +2
We present a catalogue of Molecular Hydrogen emission-line Objects (MHOs) in outflows from young stars, most of which are embedded. All objects are identified in the near-infrared…
Opendda: a Novel High-Performance Computational Framework for the Discrete Dipole Approximation
James Mc Donald, Aaron Golden, S. Gerard Jennings
This work presents a highly optimized computational framework for the Discrete Dipole Approximation, a numerical method for calculating the optical properties associated with a tar…
Radio Imaging of the Very-High-Energy Gamma-Ray Emission Region in the Central Engine of a Radio Galaxy
The VERITAS Collaboration, the VLBA 43 GHz M 87 Monitoring Team, the H. E. S. S. Collaboration +1
The accretion of matter onto a massive black hole is believed to feed the relativistic plasma jets found in many active galactic nuclei (AGN). Although some AGN accelerate particle…
Supersonic turbulence in the cold massive core JCMT 18354-0649S
P. B. Carolan, T. Khanzadyan, M. P. Redman +6
An example of a cold massive core, JCMT 18354-0649S, a possible high mass analogue to a low mass star forming core is studied. Line and continuum observations from JCMT, Mopra Tele…
Simultaneous Multiwavelength Observations of Markarian 421 During Outburst
The VERITAS Collaboration, I. de la Calle Perez, A. Ibarra +2
We report on the results of two coordinated multiwavelength campaigns that focused on the blazar Markarian 421 during its 2006 and 2008 outbursts. These campaigns obtained UV and X…
Nearby Galaxies in the 2micron All Sky Survey I. K-band Luminosity Functions
Nick Devereux, S. P. Willner, M. L. N. Ashby +2
Differential K-band luminosity functions (LFs) are presented for a complete sample of 1613 nearby bright galaxies segregated by visible morphology. The LF for late-type spirals fol…
Observation of Extended VHE Emission from the Supernova Remnant IC 443 with VERITAS
VERITAS Collaboration, V. A. Acciari, E. Aliu +90
We present evidence that the very-high-energy (VHE, E > 100 GeV) gamma-ray emission coincident with the supernova remnant IC 443 is extended. IC 443 contains one of the best-studie…
Evidence for long-term Gamma-ray and X-ray variability from the unidentified TeV source HESS J0632+057
VERITAS Collaboration, V. A. Acciari, E. Aliu +79
HESS J0632+057 is one of only two unidentified very-high-energy gamma-ray sources which appear to be point-like within experimental resolution. It is possibly associated with the m…
Multiwavelength Observations of LS I +61 303 with VERITAS, Swift and RXTE
VERITAS Collaboration, V. A. Acciari, E. Aliu +83
We present results from a long-term monitoring campaign on the TeV binary LSI +61 303 with VERITAS at energies above 500 GeV, and in the 2-10 keV hard X-ray bands with RXTE and Swi…
Gauge invariant perturbations of self-similar Lemaître-Tolman-Bondi spacetime: even parity modes with
