Fitting BICEP2 with defects, primordial gravitational waves and dust
Joanes Lizarraga, Jon Urrestilla, David Daverio +3
In this work we discuss the possibility of cosmic defects being responsible for the B-mode signal measured by the BICEP2 collaboration. We also allow for the presence of other cosm…
Constraining topological defects with temperature and polarization anisotropies
Joanes Lizarraga, Jon Urrestilla, David Daverio +3
We analyse the possible contribution of topological defects to cosmic microwave anisotropies, both temperature and polarisation. We allow for the presence of both inflationary scal…
Can topological defects mimic the BICEP2 B-mode signal?
Joanes Lizarraga, Jon Urrestilla, David Daverio +3
We show that the B-mode polarization signal detected at low multipoles by BICEP2 cannot be entirely due to topological defects. This would be incompatible with the high-multipole B…
