Gaia Data Release 3 - Stellar multiplicity, a teaser for the hidden treasure / Gaia Collaboration
Context.TheGaiaDR3 catalogue contains, for the first time, about 800 000 solutions with either orbital elements or trend parameters for astrometric, spectroscopic, and eclipsing binaries, and combinations of these three.Aims.With this paper, we aim to illustrate the huge potential of this large non-single-star catalogue.Methods.Using the orbital solutions and models of the binaries, we have built a catalogue of tens of thousands of stellar masses or lower limits thereof, some with consistent flux ratios. Properties concerning the completeness of the binary catalogues are discussed, statistical features of the orbital elements are explained, and a comparison with other catalogues is performed.Results.Illustrative applications are proposed for binaries across the Hertzsprung-Russell Diagram (HRD).

Kastler Brossel ; U. Evry) et al.
We report on the first production of an antihydrogen beam by charge exchange of 6.1 keV antiprotons with a cloud of positronium in the GBAR experiment at CERN. The antiproton beam was delivered by the AD/ELENA facility. [...]

Gaia Data Release 3 - Exploring and mapping the diffuse interstellar band at 862 nm / Gaia Collaboration
Context. Diffuse interstellar bands (DIBs) are common interstellar absorption features in spectroscopic observations but their origins remain unclear. [...]

Gaia Data Release 3: Chemical cartography of the Milky Way / Gaia Collaboration
Gaia DR3 opens a new era of all-sky spectral analysis of stellar populations thanks to the nearly 5.6 million stars observed by the RVS and parametrised by the GSP-spec module. The all-sky Gaia chemical cartography allows a powerful and precise chemo-dynamical view of the Milky Way with unprecedented spatial coverage and statistical robustness. [...]

Gaia Data Release 3: The extragalactic content / Gaia Collaboration
The Gaia Galactic survey mission is designed and optimized to obtain astrometry, photometry, and spectroscopy of nearly two billion stars in our Galaxy. Yet as an all-sky multi-epoch survey, Gaia also observes several million extragalactic objects down to a magnitude of G~21 mag. [...]

Gaia Early Data Release 3 - The celestial reference frame (Gaia-CRF3) / Gaia Collaboration
Gaia-CRF3 is the celestial reference frame for positions and proper motions in the third release of data from the Gaia mission, Gaia DR3 (and for the early third release, Gaia EDR3, which contains identical astrometric results). The reference frame is defined by the positions and proper motions at epoch 2016.0 for a specific set of extragalactic sources in the (E)DR3 catalogue. [...]

Synthesis of cold and trappable fully stripped highly charged ions via antiproton-induced nuclear fragmentation in traps / Kornakov, G. (Warsaw U. of Tech.) ; Cerchiari, G. (Innsbruck U.) ; Zieliński, J. (Warsaw U. of Tech.) ; Lappo, L. (Warsaw U. of Tech.) ; Sadowski, G. (CERN) ; Doser, M. (CERN)
The study of radioisotopes as well as of highly charged ions is a very active and dynamic field. In both cases, the most sensitive probes involve species trapped in Penning or Paul traps after a lengthy series of production and separation steps that limit the types and lifetimes of species that can be investigated. [...]
