The CMB Cold Spot under the lens II: Lensing signatures in polarization and cosmic texture footprints
Pedro da Silveira Ferreira, Stephen Owusu
We forecast the detectability of the lensing footprint of a collapsing cosmic texture, a topological defect proposed as an explanation of the CMB Cold Spot. Our pipeline is a quadr…
The CMB cold spot under the lens: ruling out a supervoid interpretation
Stephen Owusu, Pedro da Silveira Ferreira, Alessio Notari +1
The Cosmic Microwave Background (CMB) anisotropies are thought to be statistically isotropic and Gaussian. However, several anomalies are observed, including the CMB Cold Spot, an…
Oscillating soliton stars with network of domain walls
Stephen Owusu, Jose A. V. Campos, Francisco A. Brito
In this work we study oscillating soliton stars (oscillatons) with network of domain walls. We consider a Lagrangian with three scalar fields coupled among themselves by a specific…
