Do globular clusters possess Dark Matter halos? A case study in NGC 2419
(2012-10-29)We use recently published measurements of the kinematics, surface brightness and stellar mass-to-light ratio of the globular cluster NGC 2419 to examine the possibility that this Galactic halo satellite is embedded in a ... -
Do submillimeter galaxies really trace the most massive dark matter halos? Discovery of a high-z cluster in a highly active phase of evolution
(2009-01-20)We present detailed observations of a z~1.99 cluster of submillimeter galaxies (SMGs), discovered as the strongest redshift spike in our entire survey of ~100 SMGs across 800 square arcmin. It is the largest blank-field ... -

Draco, a flawless dwarf galaxy
(2007-03-01)The Draco dwarf spheroidal galaxy (dSph), with its apparent immense mass to light ratio and compact size, holds many clues to the nature of the enigmatic dark matter. Here we present deep photometric studies of this dwarf ... -

Dynamical Structure of the Molecular Interstellar Medium in an Extremely Bright, Multiply Lensed z 3 Submillimeter Galaxy Discovered with Herschel
(2011-05-20)We report the detection of CO 5-4, 3-2, and 1-0 emission in the strongly lensed, Herschel/SPIRE-selected submillimeter galaxy (SMG) HLSW-01 at z=2.9574+/-0.0001, using the Plateau de Bure Interferometer, the Combined Array ... -
Dynamics in the satellite system of Triangulum: Is AndXXII a dwarf satellite of M33?
(2012-06-25)We present results from a spectroscopic survey of the dwarf spheroidal And XXII and the two extended clusters EC1 and EC2. These three objects are candidate satellites of the Triangulum galaxy, M33, which itself is likely ... -
Dynamics of dislocations and surface instabilities in misfitting heteroepitaxial films

Effect of finite mean free path on spin-flip scattering rates near the critical point of magnetically ordered systems
(1985)The finite electron mean free path of conduction electrons is found to play an important role in determining spin-flip scattering rates, 1/sf, near a magnetic critical point. Small-momentum-transfer processes are suppressed ... -
The effect of lensing on the identification of bright SCUBA galaxies
(2002-09)Spectroscopic surveys of luminous submillimetre-selected sources have uncovered optically-bright galaxies at z<1 close to the positions of several submillimetre (submm) sources. Naive statistical analyses suggest that ... -
The effect of meteorological and chemical factors on the agreement between observations and predictions of fine aerosol composition in southwestern Ontario during BAQS-Met
(2011)The Border Air Quality and Meteorology Study (BAQS-Met) was an intensive, collaborative field campaign during the summer of 2007 that investigated the effects of transboundary pollution, local pollution, and local ... -

Effects of rapid thermal annealing on the optical properties of low-loss 1.3 mu m GaInNAs/GaAs saturable Bragg reflectors
(2004-08)We report studies of the effect of rapid thermal annealing (RTA) on the optical properties of a low-loss 1.3 mum saturable Bragg reflector (SBR), consisting of a GaInNAs/GaAs single quantum well embedded in an AlAs/GaAs ... -

Elucidating determinants of aerosol composition through particle-type-based receptor modeling
(2011)An aerosol time-of-flight mass spectrometer (ATOFMS) was deployed at a semi-rural site in southern Ontario to characterize the size and chemical composition of individual particles. Particle-type-based receptor modelling ...
