TL;DR: In this paper, the relationship between the X-ray-determined bolometric luminosity, LX, the temperature, T, of the intracluster gas, and the optical measured velocity dispersion of the cluster galaxies are updated for galaxy clusters using the largest sample of 256 clusters drawn from literature.

TL;DR: In this article, the authors present an extensive study of the relations between the X-ray luminosity (LX), the temperature (T) of hot diffuse gas, and the velocity dispersion (σ) of galaxies for groups and clusters of galaxies, based on the largest sample of 66 groups and 274 clusters drawn from the literature.

TL;DR: In this article, the relationship between the X-ray determined bolometric luminosity Lx, the temperature T of the intracluster gas, and the optical measured velocity dispersion sigma of the cluster galaxies is updated for galaxy clusters using the largest sample of 256 clusters drawn from literature.

TL;DR: In this paper, radio galaxies can heat and support the cluster gas with injected cosmic-ray protons and magnetic field densities, which are permitted by Faraday rotation and gamma-ray observations of clusters of galaxies.

TL;DR: The giant radio array for neutrino detection (GRAND) is a planned large-scale observatory of ultra-high-energy (UHE) cosmic particles, with energies exceeding 10^8 GeV.
