TL;DR: In order to investigate the nature and characteristics of the motions of very faint objects, a flexibly-pointed instrument capable of high astrometric accuracy is an ideal complement to current sky survey telescopes and a unique tool for precision astrophysics as mentioned in this paper.

TL;DR: A software application is developed to simulate generic clock frameworks for Gaia, which requires a high stability clock signal for which a Rb-type spacecraft master clock has been baselined.
Reduction of the Gaia astrometric data
TL;DR: The role of Spain and of the national supercomputing centre (CNS-BSC) in this work is described, and some of the most critical points in modelling the instrument and in the observations are described.
Implementation of the rROF denoising method in the cWB pipeline for gravitational-wave data analysis
TL;DR: In this article , the authors discuss the implementation of two variants of the regularized Rudin-Osher-Fatemi (rROF) model as two separate plug-ins of the coherent Wave Burst (cWB) pipeline designed to conduct searches of unmodelled gravitational-wave burst sources.
