Deep Chandra observations of the NGC 4472 globular cluster black hole XMMU 1229397+075333: short-term variability from the first globular cluster black hole binary

Joseph, Tana D., Maccarone, Thomas J., Kraft, Ralph P., Sivakoff, Gregory Robert
In this paper, we discuss the luminosity modulations and spectral analysis results of the recent deep observations of XMMU 122939.7+075333, the first black hole discovered in a globular cluster. The source has been detected many times, typically with LX > 1039 erg s−1, but in a 2010 observation...

Deep mitochondrial DNA lineage divergences within Alberta populations of Dermacentor albipictus (Acari: Ixodidae) do not indicate distinct species

Leo, S.S.T., Pybus, M.J., Sperling, F.A.H.
The winter tick Dermacentor albipictus (Packard) has a single-host life cycle that allows it to reach severe infestation levels on ungulates, particularly moose, Genotypic variation within these and related ticks has been a source of taxonomic confusion, although the continuity in their...

Deep radio imaging of 47 Tuc identifies the peculiar X-ray source X9 as a new black hole candidate

Miller-Jones, James C. A., Strader, Jay, Heinke, Craig O., Maccarone, Thomas J., van den Berg, Maureen, Knigge, C., Chomiuk, Laura, Noyola, Eva, Russell, Thomas D., Seth, Anil C., Sivakoff, Gregory Robert
We report the detection of steady radio emission from the known X-ray source X9 in the globular cluster 47 Tuc. With a double-peaked C IV emission line in its ultraviolet spectrum providing a clear signature of accretion, this source had been previously classified as a cataclysmic variable. In...

The author addresses two perennial problems in Canadian administrative law: the choice of a standard of review and the inconsistent application of the reasonableness standard. With these problems in mind, the Supreme Court of Canada in Dunsmuir set out to establish a 'principled framework that is...

Although widely used, the term repellency needs to be employed with care when applied to ticks and other periodic or permanent ectoparasites. Repellency has classically been used to describe the effects of a substance that causes a flying arthropod to make oriented movements away from its source....

Definition and interpretation of fact in Canadian Aboriginal title litigation: A comment on Delgamuukw
Download1994
Asch, Michael, Bell, Catherine
Professors Asch and Bell argue that Aboriginal title litigation presents a unique set of evidentiary problems both for Aboriginal plaintiffs and the courts. The elements of proof of title are themselves imbued with an ethnocentrism which serves to ignore Aboriginal systems of land ownership and...

Deformation and evolution of solar wind discontinuities through their interactions with the Earth's bow shock
Download2009
Kabin, Konstantin, Keika, Kunihiro, Rankin, Robert, Carr, C. M., Carlson, C. W., Glassmeier, Karl-Heinz, Magnes, Werner, Lucek, Elizabeth, McFadden, J. P., Dandouras, Iannis, Auster, H. U., Sibeck, D. G., Fornacon, K.-H., Angelopoulos, Vassilis, Baumjohann, W., Nakamura, Rumi
The present study examines the interaction of solar wind discontinuities with the Earth's bow shock, using multipoint observations in the magnetosheath by Time History of Events and Macroscale Interactions During Substorms (THEMIS), Cluster, and Double Star TC1. We focus on the deformation and...

Guenot, A., Morgenstern, N., Kaiser, P. K.
Tests on small circular openings have been conducted to investigate the deformation processes near tunnels at large depth or in weak rock. The test equipment has been described in Part 1; typical test results documenting the behaviour of small tunnels in a jointed rock mass with time-dependent...
