TL;DR: The CMB-S4 project as mentioned in this paper is a ground-based cosmic microwave background (CMB) experiment with superconducting cameras, which will be used for the search for the B-mode polarization signature of primordial gravitational waves and the determination of the number and masses of neutrinos.

TL;DR: In this paper, the authors performed a joint analysis of galaxy-galaxy weak lensing, galaxy spatial clustering, and galaxy number densities using a self-consistent theoretical framework.
Journal ArticleDOI
Solar System constraints to general f(R) gravity
TL;DR: In this paper, it was shown that the vacuum field equations for 1/R gravity around a spherically symmetric mass also yield gamma = 1/2, which is far outside the range allowed by observations.
