Vertex Operators and Modular Forms
(2009)
The leitmotif of these Notes is the idea of a vertex operator algebra (VOA) and the relationship between VOAs and elliptic functions and modular forms. This is to some extent analogous to the relationship between a finite ...
The Virasoro Algebra and Some Exceptional Lie and Finite Groups
(2006)
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 groups include the Deligne exceptional series ...
Monstrous and Generalized Moonshine and Permutation Orbifolds
(2008)
We consider the application of permutation orbifold constructions towards a new possible understanding of the genus zero property in Monstrous and Generalized Moonshine. We describe a theory of twisted Hecke operators in ...
Very High Energy Observations of Gamma-Ray Burst Locations with the Whipple Telescope
(2007)
Gamma-ray burst (GRB) observations at very high energies (VHE, E > 100 GeV) can impose tight constraints on some GRB emission models. Many GRB afterglow models predict a VHE component similar to that seen in blazars and ...
Discovery of Spectral Variability of Markarian 421 at TeV Energies
(2002)
The detection of spectral variability of the gamma-ray blazar Mrk 421 at TeV energies is reported. Observations with the Whipple Observatory 10m gamma-ray telescope taken in 2000/2001 revealed exceptionally strong and ...
Cutoff in the TeV Energy Spectrum of Markarian 421 During Strong Flares in 2001
(2001)
Exceptionally strong and long lasting flaring activity of the blazar Markarian 421 (Mrk 421) occurred between January and March 2001. Based on the excellent signal-to-noise ratio of the data we derive the energy spectrum ...
Recent Results from the VERITAS Collaboration
(2002)
A decade after the discovery of TeV gamma-rays from the blazar Mrk 421 (Punch et al. 1992), the list of TeV blazars has increased to five BL Lac objects: Mrk 421 (Punch et al. 1992; Petry et al. 1996; Piron et al. 2001), ...
Syntheses of C-substituted icosahedral dicarbaboranes bearing the 8-dioxane-cobalt bisdicarbollide moiety
(Elsevier, 2009-11-20)
The treatment of 1,2-, 1,7- and 1,12-carbaborane lithiated isomers with [3,3′-Co-8-(CH2CH2O)2-(1,2-C2B9H10)-(1′,2′-C2B9H11)] (1) at molar ratios 1:1 or 1:2 at room temperature in THF leads generally to the formation of a ...
Hydrocarbon fluid inclusion fluorescence: A review
(Springer, 2007)
Geological fluid inclusions are small voids that can contain a variety of liquids which are often found in natural minerals and rocks. Typically they are less than 10 micrometres in size that host fossil fluids which existed ...
Time-resolved fluorescence microspectroscopy for characterizing crude oils in bulk and hydrocarbon bearing fluid inclusions.
(Ingenta, 2004)
Time-resolved fluorescence data was collected from a series of 23 bulk crude petroleum oils and six microscopic hydrocarbon-bearing fluid inclusions (HCFI). The data was collected using a diode laser fluorescence lifetime ...
