TL;DR: The Space Interferometry Mission PlanetQuest (SIM PlanetQuest) as discussed by the authors was the first interferometer designed for precision astrometry, achieving a parallax of about 4 μas on targets as faint as V = 20, and differential accuracy of 0.6 μas.

Sinclair,Roger W Clay +26 more
TL;DR: In this article, it was shown that Cen A is a low-luminosity FR I?type source and in general has the properties observed in other FR I radio galaxies, and that the estimated times of component ejection from the compact core are reasonably coincident with enhancements in hard X-ray intensity and 22 GHz flux density.
Journal ArticleDOI
Stellar encounters with the solar system
J. García-Sánchez,Paul R. Weissman,Robert A. Preston,Dayton L. Jones,Jean-Francois Lestrade,David W. Latham,Robert P. Stefanik,Josep M. Paredes +7 more
TL;DR: Garcia-S anchez et al. as mentioned in this paper integrated all trajectories using three dierent models of the galactic potential: a local potential model, a global potential model and a perturbative potential model.

D. Murray,George D. Nicolson,A. P. Rao,A. Savage,M. W. Sinclair,L. Skjerve,L. Taaffe,R. M. Wark,Graeme L. White +34 more
TL;DR: In this article, high-resolution radio images of PKS1830 - 211 are obtained to study the possibility that the double structure is a gravitationally lensed object, and the VLBI observations, taken from interferometric radiotelescope networks, reveal an elliptical ring connecting two bright spots of similar composition.

TL;DR: In this paper, the authors present a purely commensal survey experiment for fast (<5 s) transient radio sources, which covers the enormous volume of transients parameter space made available by ASKAP, with an unprecedented combination of sensitivity and field of view.
