Dark neutrino interactions make gravitational waves blue
New interactions of neutrinos can stop them from free streaming in the early
Universe even after the weak decoupling epoch. This results in the enhancement
of the primordial gravitational wave amplitude on small scales compared to the
standard CDM prediction. In this paper we calculate the effect of dark
matter neutrino interactions in CMB tensor -modes spectrum. We show that the
effect of new neutrino interactions generates a scale or dependent
imprint in the CMB -modes power spectrum at . In the event
that primordial -modes are detected by future experiments, a departure from
scale invariance, with a blue spectrum, may not necessarily mean failure of
simple inflationary models but instead may be a sign of non-standard
interactions of relativistic particles. New interactions of neutrinos also
induce a phase shift in the CMB B-mode power spectrum which cannot be mimicked
by simple modifications of the primordial tensor power spectrum. There is rich
information hidden in the CMB -modes spectrum beyond just the tensor to
scalar ratio.Comment: 31 pages, 10 figures. Version published in Phys. Rev.

Effect of pooled extraction replicate number on silhouette score.
<p>Mean silhouette scores were calculated based on repeated random selection of replicates to pool and sub-sampling of OTUs to a total sequence depth of 15,000 reads per sample (divided equally between selected replicates). Filtering to protist or metazoan OTUs was carried out after sub-sampling. Error bars represent bootstrapped standard errors.</p
Effect of pooled extraction replicate number on OTU richness and Shannon diversity.
<p>Mean diversity estimates based on repeated (i = 100) random selection of replicates to pool followed by random sub-sampling of OTUs to a total sequence depth of 15,000 reads per sample (divided equally between selected replicates). Filtering to protist or metazoan OTUs was carried out after sub-sampling. Error bars represent the standard error of values from the bootstrapping procedure described above.</p
Rarefaction comparing expected OTU richness of pooled samples (grey lines) and individual replicates (black lines).
<p>Only replicates with more than 15,000 reads were included from the samples Fine Sand (A; n = 5), Coarse Sand (B; n = 7) and Clay (C, n = 5). Panel D shows expected richness in pooled samples compared to mean expected replicate richness. Error bars represent standard error, for pooled samples calculated as described in Heck et al [<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0179443#pone.0179443.ref047" target="_blank">47</a>].</p
Expected OTU richness as a function of sequence depth (rarefaction).
<p><i>In silico</i> pooled replicates are shown as dashed lines and individual extraction replicates as solid lines. In panel A richness up to the maximum read number for pooled replicates and in B the same rarefaction curves up to maximum read number for individual replicates. Error bars (in B) represent standard error, for pooled samples calculated as described in Heck et al [<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0179443#pone.0179443.ref047" target="_blank">47</a>].</p
