Challenges for creating magnetic fields by cosmic defects
Lukas Hollenstein, Chiara Caprini, Robert Crittenden +1
We analyse the possibility that topological defects can act as a source of magnetic fields through the Harrison mechanism in the radiation era. We give a detailed relativistic deri…
The effect of reionization on the CMB-density correlation
Tommaso Giannantonio, Robert Crittenden
In this paper we show how the rescattering of CMB photons after cosmic reionization can give a significant linear contribution to the temperature-matter cross-correlation measureme…
Measuring deviations from a cosmological constant: a field-space parameterization
Robert Crittenden, Elisabetta Majerotto, Federico Piazza
Most parameterizations of the dark energy equation of state do not reflect realistic underlying physical models. Here, we develop a relatively simple description of dark energy bas…
