**The Cosmological Constant**

by Sean M. Carroll

**Publisher**: arXiv 2000**Number of pages**: 50

**Description**:

This is a review of the physics and cosmology of the cosmological constant. Focusing on recent developments, the author presents a pedagogical overview of cosmology in the presence of a cosmological constant, observational constraints on its magnitude, and the physics of a small (and potentially nonzero) vacuum energy.
