Cosmic string loops and large-scale structure
P. P. Avelino, E. P. S. Shellard, J. H. P. Wu +1
We investigate the contribution made by small loops from a cosmic string network as seeds for large-scale structure formation. We show that cosmic string loops are highly correlate…
Spectrum of radiation from axion strings
R. A. Battye, E. P. S. Shellard
In the wide variety of axion cosmologies in which axion strings form, their radiative decay is the dominant mechanism for the production of axions, imposing a tight constraint on t…
On the origin of dark matter axions
E. P. S. Shellard, R. A. Battye
We discuss the possible sources of dark matter axions in the early universe. In the standard thermal scenario, an axion string network forms at the Peccei-Quinn phase transition $T…
Non-gaussian Features of Linear Cosmic String Models
P. P. Avelino, E. P. S. Shellard, J. H. P. Wu +1
We investigate the non-gaussian properties of cosmic-string-seeded linear density perturbations with cold and hot dark matter backgrounds, using high-resolution numerical simulatio…
Cosmic Axions
E. P. S. Shellard, R. A. Battye
The current cosmological constraints on a dark matter axion are reviewed. We describe the basic mechanisms by which axions are created in the early universe, both in the standard t…
