Observations of the Unidentified TeV Gamma-Ray Source TeV J2032+4130 with the Whipple Observatory 10 m Telescope
A. Konopelko, R. W. Atkins, G. Blaylock +58
We report on observations of the sky region around the unidentified TeV gamma-ray source TeV J2032+4130 carried out with the Whipple Observatory 10 m atmospheric Cherenkov telescop…
Canonical Formulation of A Bosonic Matter Field in 1+1 Dimensional Curved Space
R. N. Ghalati, D. G. C. McKeon, T. N. Sherry
We study a Bosonic scalar in 1+1 dimensional curved space that is coupled to a dynamical metric field. This metric, along with the affine connection, also appears in the Einstein-H…
The Virasoro Algebra and Some Exceptional Lie and Finite Groups
Michael P. Tuite
We describe a number of relationships between properties of the vacuum Verma module of a Virasoro algebra and the automorphism group of certain vertex operator algebras. These grou…
Evidence of Precession of the White Dwarf in Cataclysmic Variables
G. Tovmassian, S. Zharikov, V. Neustroev
Cataclysmic Variables (CV) are close binary systems, in which the primary, the more massive star, is a white dwarf. CVs usually exhibit a number of periodicities, most of which are…
Whipple Telescope Observations of LS I +61 303: 2004-2006
Andy Smith
In this paper we present the results of the past two years' observations on the galactic microquasar LS I +61 303 with the Whipple 10m gamma-ray telescope. The recent MAGIC detecti…
Nonstationary Increments, Scaling Distributions, and Variable Diffusion Processes in Financial Markets
Kevin E. Bassler, Joseph L. McCauley, Gemunu H. Gunaratne
Arguably the most important problem in quantitative finance is to understand the nature of stochastic processes that underlie market dynamics. One aspect of the solution to this pr…
Short time scale pulse stability of the Crab pulsar in the optical band
S. Karpov, G. Beskin, A. Biryukov +4
The fine structure and the variations of the optical pulse shape and phase of the Crab pulsar are studied on various time scales. The observations have been carried out on 4-m Will…
Hurst Exponents, Markov Processes, and Fractional Brownian motion
Joseph L. McCauley, Gemunu H. Gunaratne, Kevin E. Bassler
There is much confusion in the literature over Hurst exponents. Recently, we took a step in the direction of eliminating some of the confusion. One purpose of this paper is to illu…
Rotational Modulation of the Radio Emission from the M9 Dwarf TVLM 513-46546: Broadband Coherent Emission at the Substellar Boundary?
G. Hallinan, A. Antonova, J. G. Doyle +3
The Very Large Array was used to observe the ultracool, rapidly rotating M9 dwarf TVLM 513-46546 simultaneously at 4.88 GHz and 8.44 GHz. The radio emission was determined to be pe…
A deep mosaic of [O III] 5007 A CCD images of the environment of the LBV star P Cygni
P. Boumis, J. Meaburn, M. P. Redman +1
A mosaic of six, deep, CCD images in the light of the [O III] 5007 A nebular emission line has been obtained with the 1.3-m Skinakas (Crete) telescope of the filamentary nebulosity…
Fixed point theory for composite maps on almost dominating extension spaces
Ravi P Agarwal, Jong Kyu Kim, Donal O'Regan
New fixed point results are presented for maps in extension type spaces.
Martingale Option Pricing
J. L. McCauley, G. H. Gunaratne, K. E. Bassler
We show that our generalization of the Black-Scholes partial differential equation (pde) for nontrivial diffusion coefficients is equivalent to a Martingale in the risk neutral dis…
Response to Worrying Trends in Econophysics
Joseph L. McCauley
This article is a response to the recent Worrying Trends in Econophysics critique written by four respected theoretical economists. Two of the four have written books and papers th…
The First VERITAS Telescope
J. Holder, R. W. Atkins, H. M. Badran +73
The first atmospheric Cherenkov telescope of VERITAS (the Very Energetic Radiation Imaging Telescope Array System) has been in operation since February 2005. We present here a tech…
Oscillations in the stable starless core Barnard 68
M. P. Redman, E. Keto, J. M. C. Rawlings
New molecular line observations of the Bok globule Barnard 68 in HCO+ irrefutably confirm the complex pattern of red and blue asymmetric line profiles seen across the face of the c…
Simultaneous photometry and echelle-spectroscopy of the dwarf nova BZ Ursae Majoris during the 2005 January Outburst
V. V. Neustroev, S. V. Zharikov, R. Michel
We report simultaneous photometric and echelle-spectroscopic observations of the dwarf nova BZ UMa during which we were lucky to catch the system at the onset of an outburst, the d…
On Genus Two Riemann Surfaces Formed from Sewn Tori
Geoffrey Mason, Michael P. Tuite
We describe the period matrix and other data on a higher genus Riemann surface in terms of data coming from lower genus surfaces via an explicit sewing procedure. We consider in de…
Multiwavelength Observations of 1ES 1959+650, One Year After the Strong Outburst of 2002
K. Gutierrez, H. M. Badran, S. M. Bradbury +33
In April-May 2003, the blazar 1ES 1959+650 showed an increased level of X-ray activity. This prompted a multiwavelength observation campaign with the Whipple 10 m gamma-ray telesco…
Markov Processes, Hurst Exponents, and Nonlinear Diffusion Equations with application to finance
Kevin E. Bassler, Gemunu H. Gunaratne, Joseph L. McCauley
We show by explicit closed form calculations that a Hurst exponent H that is not 1/2 does not necessarily imply long time correlations like those found in fractional Brownian motio…
TeV Gamma-Ray Observations of the Perseus and Abell 2029 Galaxy Clusters
J. S. Perkins, H. M. Badran, G. Blaylock +41
Galaxy clusters might be sources of TeV gamma rays emitted by high-energy protons and electrons accelerated by large scale structure formation shocks, galactic winds, or active gal…
