dc.descriptionWithin a string cosmology context, the large scale temperature anisotropies may arise from the contribution of seeds to the metric fluctuations. We study the cases of electromagnetic and axion seeds. We find that massless or very light axions can lead to a flat or slightly tilted blue spectrum, that fits current data.
