Understanding the nature of the optically faint radio sources and their connection to the submillimeter population
(2002-05-10)
We present a sample of 43 submillimeter sources detected (at >3 sigma), drawn from our program to follow-up optically faint radio sources with SCUBA. These sources already have associated radio and in many cases optical ...
Near-IR adaptive optics imaging of nuclear spiral structure in the Seyfert galaxy, NGC3227
(2002-04-04)
We present high spatial resolution, near-IR images in J, H, K of the nucleus of NGC3227, obtained with the Adaptive Optics bonnette on CFHT. The ~0.15 arcsec (17pc) resolution allows structures to be probed in the core ...
Westphal-MMD11: An interacting, submillimeter luminous Lyman break galaxy
(2002-6-10)
We present new Hubble Space Telescope, high-resolution optical imaging of the submm luminous Lyman-break galaxy, Westphal-MMD11, an interacting starburst at z=2.979. The new imaging data, in conjunction with re-analysis ...
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 ...
Coherent response of spin-orbit split-off excitons in InP: Isolation of many-body effects through interference

Individual variation in Atlantic salmon fertilization success: Implications for effective population size
(2002-02)
Mating structure can influence the variance in individual reproductive success, which in turn
has important implications for a population's effective size. Atlantic salmon (Salmo salar)
males are characterized by alternative ...
Complex interactions of climatic and ecological controls on macroalgal recruitment.
(2002-11)
Little is known about the cumulative effects of multiple (>2) environmental controls on species performance and interactions in aquatic ecosystems. We asked how changes in climatic (temperature, ultraviolet radiation) and ...

Assessment of the relationships between dominant cell size in natural phytoplankton communities and the spectral shape of the absorption coefficient
(2002-03)
Size-fractionated chlorophyll concentration and phytoplankton absorption spectra were compared for a wide variety of natural communities. We found that, in general, when phytoplankton abundance increases, larger size-classes ...
