FAST in Space: Considerations for a Multibeam, Multipurpose Survey Using China's 500-m Aperture Spherical Radio Telescope (FAST)
Di Li,Pei Wang,Lei Qian,Marko Krco,A. Dunning,Peng Jiang,Youling Yue,Chenjin Jin,Yan Zhu,Zhichen Pan,Rendong Nan +10 more
TL;DR: In this paper, the authors devised a survey plan to exploit the full sensitivity of FAST, while minimizing the complexities involved during system operation, and the 19-beam L-band focal plan array will be rotated to specific angles and receive continuous data streams, while the surface shape and the focal cabin stay fixed.

TL;DR: An ultra-wide-bandwidth, low-frequency receiver recently installed on the Parkes radio telescope is described, including its astronomical objectives, as well as the feed, receiver, digitiser, and signal processor design.
Journal ArticleDOI
Sensitivity of hyperfine structure to nuclear radius and quark mass variation
TL;DR: In this article, the dependence of the hyperfine structure of atomic levels on nuclear radius and, via radius, on quark masses has been studied, and an analytical formula has been derived and tested by the numerical relativistic Hartree-Fock calculations for Rb, Cd, Cs, Yb, and Hg.
Journal Article
A Simple Orthomode Transducer for Centimeter to Submillimeter Wavelengths
TL;DR: In this article, a simple orthomode transducer suitable for operation from centimeter to submillimeter wavelengths with appropriate scaling is described, which operates over a 1.3:1 frequency band, narrower than a full waveguide band (typically 1.5:1).
