Warm Dark Matter, Small Scale Crisis, and the High Redshift Universe

TL;DR: In this paper, a root-mean-square velocity dispersion v(rms) = 0.05 km/s at redshift z = 0, corresponding to a particle mass of 1 keV if the WDM particles are fermions decoupling while relativistic.
Journal ArticleDOI

Cosmic Mach Number: A Sensitive Probe for the Growth of Structure

TL;DR: In this article, the potential power of the cosmic Mach Number (CMN), which is the ratio between the mean velocity and the velocity dispersion of galaxies as a function of cosmic scales, was investigated to constrain cosmologies.

The imminent detection of gravitational waves from massive black-hole binaries with pulsar timing arrays

TL;DR: In this article, the authors calculate the merger-driven evolution of the mass function and find that merger rates are 10 to 30 times higher and gravitational waves are 3 to 5 times stronger than previously estimated, so that the gravitational wave signal may already be detectable with existing data from pulsar timing arrays.
