Status of Cosmology
TL;DR: The cosmological parameters that were emphasized in this article are the Hubble parameter, the age of the universe, the average matter density, the baryonic matter density and the neutrino density.

Joel R. Primack,Aaron Dominguez,Aaron Dominguez,Aaron Dominguez,Rudy C. Gilmore,Rudy C. Gilmore,Rachel S. Somerville +6 more
TL;DR: In this article, the extragalactic background light (EBL) from the UV to the mid-IR was compared with the gamma ray attenuation from active galactic nuclei (AGN) and gamma ray bursts (GRBs).
Journal ArticleDOI
Spherically symmetric monopoles in non-abelian gauge theories
F.A. Bais,Joel R. Primack +1 more
TL;DR: In this paper, a method for constructing point-singular spherically symmetric monopoles in theories with an arbitrary compact simple gauge group was developed, where the monopole can be constructed by a simple group.
Journal ArticleDOI
The Origin and Distribution of Angular Momentum in Galaxies
TL;DR: The angular momentum of dark matter halos, and presumably that of the galaxies they host, appears to arise largely from the orbital angular momentum (OAM) of the satellites that they accrete as discussed by the authors.
