Fall 1969
Refraction arrivals from the upper mantle were recorded on a 3500 km. profile stretching from Lake Superior to Alaska. Recordings from the middle section of the profile (1000 - 2000 km.) were digitized, and various frequency and velocity filters were used to enhance this data. One version of the...

Neutron stars are interesting due to their extremely large densities (∼ 1015 g/cm^3), and also because the accretion of matter from a companion star can spin them up to very high frequencies (∼716 Hz based on observations ). When we study black holes (BH), the only thing that we have to worry...

Fall 2013
The equation of state for cold ultra-dense matter has puzzled astrophysicists for decades. This is because the conditions of supra-nuclear density matter, such as those in neutron stars, are not terrestrially replicable. X-ray light curves from accreting neutron stars have proven to be useful...

Ultrasonic Characterization of Bitumen with Pressure and Temperature: Implications for seismic monitoring of the Grosmont Formation
DownloadFall 2018
The vastly untapped carbonate Grosmont Formation in north-eastern Alberta may hold in excess of a couple of hundred billion barrels initial volume of bitumen in place. Bitumen, an ultra-heavy hydrocarbon oil, possesses a density comparable to water, but a dynamic shear viscosity million times...

Positronium consists of an electron and positron in a bound state, a purely leptonic system and therefore an excellent test of QED (quantum electrodynamics). The ground state is characterized by two different spin configurations: spin-singlet and spin-triplet states. The difference between the...
