A dedicated mission to investigate exoplanetary atmospheres represents a major milestone in our quest to understand our place in the universe by placing our Solar System in context and by addressing the suitability of planets for the presence of life. EChO – the Exoplanet Characterisation Observatory – is a mission concept specifically geared for this purpose. EChO will provide simultaneous, mu...

Future studies of episodic processes in the ocean and earth will require new tools to complement traditional, ship-based, expeditionary science. This will be enabled through the construction of innovative facilities called ocean observatories which provide unprecedented amounts of power and two-way bandwidth to access and control instrument networks in the oceans. The most capable ocean observa...

The existing waveguide interface standards are generally found to be unsatisfactory above 110 GHz. An improved interface is proposed which is backward-compatible with the MIL-DTL-3922/67C standard and most of its higher-frequency variants. As there are currently no standard waveguide bands above 325 GHz, an extended set of bands is recommended for operation to 1100 GHz. Index Terms — Waveguides...

The results presented herein are based on data obtained at the WIYN telescope and at the McMathPierce Solar Telescope, respectively. The WIYN Observatory is a joint facility of the University of WisconsinMadison, Indiana University, Yale University, and the National Optical Astronomy Observatory. The McMath-Pierce Solar Telescope Facility is operated by the National Solar Observatory for the Na...
