Lower bounds on photometric redshift errors from Type Ia supernovae templates (2009)

Asztalos, S., Nikolaev, S., De Vries, W., Olivier, S., Cook, K., Wang, L.

Cosmology with Type Ia supernovae heretofore has required extensive spectroscopic follow-up to establish a redshift. Though tolerable at the present discovery rate, the next generation of...

A Census of Exoplanets in Orbits Beyond 0.5 AU via Space-based Microlensing (2009)

Bennett, David P., Anderson, J., Bond, I., Cheng, E., Cook, K., ...

A space-based gravitational microlensing exoplanet survey will provide a statistical census of exoplanets with masses greater than 0.1 Earth-masses and orbital separations ranging from 0.5AU to...

Compression of picosecond optical pulses in tapered hollow-core photonic bandgap fiber (2008)

Cook, K, Welch, M. G., Gerome, F, George, A. K, Wadsworth, W. J., Knight, J. C.

We demonstrate nonlinear compression of 2.5ps and 1.2ps laser pulses at 800nm wavelength using a 35m tapered hollow-core photonic bandgap fiber with continuously-decreasing dispersion.

Delivery of sub-100fs pulses through 8m of hollow-core fiber using soliton compression (2007)

Gerome, F., Cook, K., George, A. K., Wadsworth, W. J., Knight, J. C.

Further empirical evidence for the non-linearity of the period-luminosity relations as seen in the Large Magellanic Cloud Cepheids (2005)

Ngeow, C., Kanbur, S., Nikolaev, S., Buonaccorsi, J., Cook, K., Welch, D.

(abridged) Recent studies, using OGLE data for LMC Cepheids in the optical, strongly suggest that the period-luminosity (PL) relation for the Large Magellanic Cloud (LMC) Cepheids shows a break or...

An overview of Calanus helgolandicus ecology in European waters (2005)

Bonnet, D., Richardson, A., Harris, R., Hirst, A., Beaugrand, G., Edwards, M., ...

We review current knowledge and understanding of the biology and ecology of the calanoid copepod Calanus helgolandicus in European waters, as well as provide a collaborative synthesis of data from 18...

Adaptive Optics High Resolution Spectroscopy: Present Status and Future Direction (2000)

Ge Ciarlo Kuzmenko, J. Ge, D. Ciarlo, P. Kuzmenko, C. Alcock, B. Macintosh, ...

. High resolution spectroscopy experiments with visible adaptive optics telescopes at Starfire Optical Range and Mt. Wilson have demonstrated that spectral resolution can be routinely improved by a...

The Performance and Scientific Rationale for an Infrared Imaging Fourier Transform Spectrograph on a Large Space Telescope (1998)

James R. Graham, Mark Abrams, C. Bennett, J. Carr, K. Cook, A. Dey, ...

ABSTRACT. We describe a concept for an imaging spectrograph for a large orbiting observatory such as NASA’s proposed Next Generation Space Telescope (NGST) based on an imaging Fourier transform...
