The pure-rotational and rotational-vibrational Raman spectrum of the atmosphere at an altitude of 23 km
F. P. A. Vogt, A. Mehner, P. Figueira +5
Ground-based optical astronomical observations supported by or in the vicinity of laser guide-star systems can be contaminated by Raman-scattered laser photons. Anticipating, allev…
Measuring line-of-sight sodium density structure using laser guide stars
Joschua A. Hellemeier, Domenico Bonaccini Calia, Paul Hickson +2
The performance of adaptive optics systems employing sodium laser guide stars can be improved by continuously monitoring the vertical density structure of mesospheric sodium along…
Rotational and rotational-vibrational Raman spectroscopy of air to characterize astronomical spectrographs
F. P. A. Vogt, F. Kerber, A. Mehner +14
Raman scattering enables unforeseen uses for the laser guide-star system of the Very Large Telescope. Here, we present the observation of one up-link sodium laser beam acquired wit…
Astronomical seeing and ground-layer turbulence in the Canadian High Arctic
P. Hickson, R. Gagne, T. Pfrommer +1
We report results of a two-year campaign of measurements, during arctic winter darkness, of optical turbulence in the atmospheric boundary-layer above the Polar Environment Atmosph…
Using Site Testing Data for Adaptive Optics Simulations
Glen Herriot, David Andersen, Rod Conan +8
Astronomical Site testing data plays a vital role in the simulation, design, evaluation and operation of adaptive optics systems for large telescope. We present the example of TMT…
First Assessment of Mountains on Northwestern Ellesmere Island, Nunavut, as Potential Astronomical Observing Sites
E. Steinbring, R. Carlberg, B. Croll +6
Ellesmere Island, at the most northerly tip of Canada, possesses the highest mountain peaks within 10 degrees of the pole. The highest is 2616 m, with many summits over 1000 m, hig…
