trans-GZK Cosmic Rays: Strings, Black Holes, Neutrinos, or All Three? (2004)

Burgett, William S., Domokos, Gabor, Kovesi-Domokos, Susan

We review the scenario in which ``strongly interacting neutrinos'' are responsible for inducing airshowers with inferred energies $E > 8\times10^{19}$ eV. This possibility arises naturally in string...

Substructure Analysis of Selected Low Richness 2dFGRS Clusters of Galaxies (2004)

Burgett, William S., Vick, Michael M., Davis, David S., Colless, Matthew, De Propris, Roberto, Baldry, Ivan, ...

Complementary one-, two-, and three-dimensional tests for detecting the presence of substructure in clusters of galaxies are applied to recently obtained data from the 2dF Galaxy Redshift Survey. The...

Substructure analysis of selected low-richness 2dFGRS clusters of galaxies (2004)

Burgett, William S., Vick, Michael M., Davis, D. Scott, Colless, Matthew, De Propris, Roberto, Baldry, Ivan K., ...

Complementary one-, two- and three-dimensional tests for detecting the presence of substructure in clusters of galaxies are applied to recently obtained data from the 2dF Galaxy Redshift Survey. The...

Searching for sources of the highest energy cosmic rays: low statistics, pitfalls, and possible clues (2003)

Burgett, William S., O'Malley, Mark R.

The clustering properties of the highest energy cosmic rays and their correlations with candidate sources are re-examined using the most recently available AGASA data and a rigorous correlation...

Hints of Energy Dependences in AGASA EHECR Arrival Directions (2002)

Burgett, William S., O'Malley, Mark R.

A correlation and probability analysis of the distribution of arrival directions for a sample of AGASA events reported to have energies above 4x10^{19} eV shows the small scale clustering to remain...

Low Scale String Unification and the Highest Energy Cosmic Rays (2002)

Burgett, William S., Domokos, G., Kovesi-Domokos, S.

String unification at a scale of a few tens of TeV explains the existence of cosmic ray interactions beyond the Greisen-Zatsepin-Kuzmin (GZK) cutoff. Trans-GZK cosmic rays are neutrinos which can...

Signatures of Precocious Unification in Orbiting Detectors (2000)

Domokos, G., Kovesi-Domokos, S., Burgett, William S., Wrinkle, Jason

It has been conjectured that the string and unification scales may be substantially lower than previously believed, perhaps a few TeV. In scenarios of this type, orbiting detectors such OWL or...
