Gaia Focused Product Release: Sources from Service Interface Function image analysis: Half a million new sources in omega Centauri
(EDP Sciences, 2023)
clustered and assigned to new SIF CF or existing Gaia sources by Gaia s cross-match software. For the new sources, astrometry was calculated using the Astrometric Global Iterative Solution software, and photometry was obtained in the Gaia DR3 reference...
Methodology for obtaining the relative orbit and individual masses of Gaia astrometric binaries
(EDP Sciences, 2024-02)
component, we proposed an analytic algorithm to estimate the only two possible relative orbits and pairs of masses of main sequence (MS) astrometric binaries using all the available astrometric, photometric, and spectroscopic data from Gaia DR3. In some...
Gaia Data Release 3: Catalogue validation
(EDP Sciences, 2023-06)
[Abstract]: Context. The third Gaia data release (DR3) provides a wealth of new data products. The early part of the release, Gaia EDR3, already provided the astrometric and photometric data for nearly two billion sources. The full release now adds...
Gaia Data Release 3: Pulsations in main sequence OBAF-type stars
(EDP Sciences, 2023)
-periodic and display low amplitudes, making them challenging targets to analyse with sparse time series.
Aims. We investigate the extent to which the sparse Gaia DR3 data can be used to detect OBAF-type pulsators and discriminate them from other
types of variables. We...

FDD Channel Estimation Via Covariance Estimation in Wideband Massive MIMO Systems
(M D P I AG, 2020-02-10)
by means of the latter expression. In the case
of odd Nc, f = 0 has to be determined using (18), whereas f = 0 and f = Nc/2 have to be computed
via (18) for Nc even.

Received 13 April 2022 / Accepted 9 June 2022
ABSTRACT
Context. The Gaia DR3 catalogue contains, for the first time, about 800 000 solutions with either orbital elements...
. By increasing the number of known binary orbits by more than one order of magnitude, Gaia DR3 will provide a rich reservoir of dynamical masses and an important contribution to the analysis of stellar multiplicity. Key words. binaries: general – astrometry...
