Clustering in real space and in redshift space

TL;DR: In this article, the authors investigated the main mechanism(s) that regulate specific star formation rate (SSFR) in nearby galaxies, cross-correlating two proxies of this quantity with other physical properties (mass, metallicity, environment, morphology, and the presence of close companions) in a sample of $\sim82500$ galaxies extracted from the Sloan Digital Sky Survey (SDSS).

TL;DR: The contribution of background large-scale structure (LSS) on the projected mass distributions using SDSS multi-bands and photometric data, under the assumption of mass-to-light ratio for field galaxies, was quantified in this paper.

TL;DR: In this article, the main tests of general relativity focusing on the large scale structure and more particularly weak lensing are reviewed, and the complementarity with other tests (including those on Solar system scales and the equivalence principle) is discussed.

TL;DR: In this article, the authors explore the potential of wide field [CII] and CO intensity mapping surveys in constraining primordial non-Gaussianity (PNG) of the local shape, which induces a distinct, scale-dependent correction to the line bias.
