Axion constraints in non-standard thermal histories
Daniel Grin, Tristan L. Smith, Marc Kamionkowski
It is usually assumed that dark matter is produced during the radiation dominated era. There is, however, no direct evidence for radiation domination prior to big-bang nucleosynthe…
Nonlinear Evolution of Anisotropic Cosmological Power
Shin'ichiro Ando, Marc Kamionkowski
There has been growing interest in the possibility of testing more precisely the assumption of statistical isotropy of primordial density perturbations. If it is to be tested with…
Cosmic Microwave Background Statistics for a Direction-Dependent Primordial Power Spectrum
Anthony R. Pullen, Marc Kamionkowski
Statistical isotropy of primordial perturbations is a common assumption in cosmology, but it is an assumption that should be tested. To this end, we develop cosmic microwave backgr…
The effects of Chern-Simons gravity on bodies orbiting the Earth
Tristan L. Smith, Adrienne L. Erickcek, Robert R. Caldwell +1
One of the possible low-energy consequences of string theory is the addition of a Chern-Simons term to the standard Einstein-Hilbert action of general relativity. It can be argued…
Red Density Perturbations and Inflationary Gravitational Waves
Luca Pagano, Asantha Cooray, Alessandro Melchiorri +1
We study the implications of recent indications for a red spectrum of primordial density perturbations for the detection of inflationary gravitational waves (IGWs) with forthcoming…
Dark Matter and Dark Energy
Marc Kamionkowski
This is a short review, aimed at a general audience, of several current subjects of research in cosmology. The topics discussed include the cosmic microwave background (CMB), with…
