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…
