The Milky Way in Molecular Clouds: A New Complete CO Survey
TL;DR: In this article, a large-scale CO survey of the first and second Galactic quadrants and the nearby molecular cloud complexes in Orion and Taurus, obtained with the CfA 1.2 m telescope, was combined with 31 other surveys obtained over the past two decades with that instrument and a similar telescope on Cerro Tololo in Chile, to produce a new composite CO survey.

Effect of antenna size on gain, bandwidth, and efficiency
TL;DR: It is found that the maximum gain obtainable from a broad-band antenna is approxima tely equal t o that of the uniformly Illuminated aperture, and if higher gain is desired, the antenna mus t necessarily be a narrow-band device.

Quantitative theory of nanowire and nanotube antenna performance
Peter Burke,Shengdong Li,Zhen Yu +2 more
TL;DR: In this article, the performance of nanotubes and nanowires as antennas is analyzed, including the radiation resistance, the input reactance and resistance, and antenna efficiency, as a function of frequency and nanotube length.
