TL;DR: The publication of this French SKA white paper illustrates the strong involvement in the SKA project of the French astronomical community and of a rapidly growing number of major scientific and technological players in the fields of Big Data, high performance computing, energy production and storage, as well as system integration.

TL;DR: In this article, the authors present an analytical study of the statistical properties of integrated emission and velocity centroids for a slightly compressible turbulent slab model, to retrieve the underlying statistics of three-dimensional density and velocity fluctuations.

TL;DR: Bregaldo et al. as mentioned in this paper proposed a statistical denoising method based on wavelet phase harmonics (WPH) statistics, which characterized the coherent structures in non-Gaussian random fields and defined a generative model of the data.

TL;DR: In this paper, a data-driven approach was proposed to determine the H2 gas column densities from radio molecular line observations, which is based on the finding that molecular hydrogen is unobservable in cold molecular clouds, but the relationship between the emission of one molecular line and the column density is non-linear and sensitive to excitation conditions, optical depths, and abundance variations.

TL;DR: In this article, the Cramer Rao Bound (CRB) technique is used to analyze and estimate the precision of the physical parameters in the framework of local-thermodynamic-equilibrium excitation and radiative transfer with an additive white Gaussian noise.
