TL;DR: In this article, the authors present lists of possible members of each of the objects (75 globular clusters, 9 dwarf spheroidal galaxies, the Bootes I UFD, the LMC and SMC).
Daily processing of Gaia data
TL;DR: Some of the results obtained during the first months of nominal operations of Gaia are presented, focusing on the Initial Data Treatment system which is coordinated by the Gaia group at the University of Barcelona.

Development of Optimum Lossless Compression Systems for Space Missions
TL;DR: This work presents a method for the development of lossless compression systems achieving high compression ratios at a low processing cost while guaranteeing a reliable downlink, and presents a new entropy coder which has comparable or even better performances than those offered by most coders and guarantees high ratios in front of outliers.
