We present the science case, reference design, and project plan for the Stage-4 ground-based cosmic microwave background experiment CMB-S4.
A phantom menace? Cosmological consequences of a dark energy component with super-negative equation of state
- R. Caldwell
- Physics
- 16 August 1999
Cosmological imprint of an energy component with general equation of state
- R. Caldwell, R. Dave, P. Steinhardt
- Physics
- 7 August 1997
We examine the possibility that a significant component of the energy density of the Universe has an equation of state different from that of matter, radiation, or cosmological constant ({Lambda} ).…
Cosmic Concordance and Quintessence
- Limin Wang, R. Caldwell, J. Ostriker, P. Steinhardt
- Physics
- 27 January 1999
We present a comprehensive study of the observational constraints on spatially flat cosmological models containing a mixture of matter and quintessence—a time-varying, spatially inhomogeneous…
Phantom energy: dark energy with w <--1 causes a cosmic doomsday.
- R. Caldwell, M. Kamionkowski, N. Weinberg
- PhysicsPhysical Review Letters
- 13 August 2003
The phantom energy rips apart the Milky Way, solar system, Earth, and ultimately the molecules, atoms, nuclei, and nucleons of which the authors are composed before the death of the Universe in a "big rip".
Limits of quintessence.
- R. Caldwell, E. Linder
- PhysicsPhysical Review Letters
- 24 May 2005
We present evidence that the simplest particle-physics scalar-field models of dynamical dark energy can be separated into distinct behaviors based on the acceleration or deceleration of the field as…
The Laser Interferometer Space Antenna: Unveiling the Millihertz Gravitational Wave Sky.
- J. Baker, J. Bellovary, J. Ziemer
- Physics
- 15 July 2019
The first terrestrial gravitational wave interferometers have dramatically underscored the scientific value of observing the Universe through an entirely different window, and of folding this new…
Phantom Energy and Cosmic Doomsday
- R. Caldwell, M. Kamionkowski, N. Weinberg
- Physics
- 25 February 2003
Cosmologists have long wondered whether the Universe will eventually re-collapse and end with a Big Crunch, or expand forever, becoming increasingly cold and empty. Recent evidence for a flat…
Observational constraints on general relativistic energy conditions, cosmic matter density and dark energy from X-ray clusters of galaxies and type-Ia supernovae
- P. Schuecker, R. Caldwell, H. Bohringer, C. Collins, L. Guzzo, N. Weinberg
- Physics
- 21 November 2002
New observational constraints on the cosmic matter density Ωm and an effectively redshift-independent equation of state parameter wx of the dark energy are obtained while simultaneously testing the…
