Fitting BICEP2 with defects, primordial gravitational waves and dust
Lizarraga Olano, Joanes ; Urrestilla Urizabal, Jon ; Daverio, David; Hindmarsh, Mark; Kunz, Martin; Liddle, Andrew R. (IOP Publishing, 2015)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 cosmological sources of B-modes such as ... -
Type I Abelian Higgs strings: evolution and Cosmic Microwave Background constraints
Hindmarsh, Mark; Lizarraga Olano, Joanes ; Urrestilla Urizabal, Jon ; Daverio, David; Kunz, Martin (APS, 2019-04-26)We present results from the first simulations of networks of Type I Abelian Higgs cosmic strings to include both matter and radiation eras and cosmic microwave background (CMB) constraints. In Type I strings, the string ...
