We test the statistical isotropy and Gaussianity of the cosmic microwave background (CMB) anisotropies using observations made by the Planck satellite. Our results are based mainly on the full Planck mission for temperature, but also include some pol... Read More about Planck 2015 results: XVI. Isotropy and statistics of the CMB.

Astronomy and Astrophysics, 594, Article A7. https://doi.org/10.1051/0004-6361/201525844

The Planck High Frequency Instrument (HFI) has observed the full sky at six frequencies (100, 143, 217, 353, 545, and 857 GHz) in intensity and at four frequencies in linear polarization (100, 143, 217, and 353 GHz). In order to obtain sky maps, the... Read More about Planck 2015 results. VII. High Frequency Instrument data processing: time-ordered information and beams.

The European Space Agency’s Planck satellite, which is dedicated to studying the early Universe and its subsequent evolution, was launched on 14 May 2009. It scanned the microwave and submillimetre sky continuously between 12 August 2009 and 23 Octob... Read More about Planck 2015 results. I. Overview of products and scientific results.

CMB constraints on cosmic strings and superstrings (2016)
Journal Article
Charnock, T., Avgoustidis, A., Copeland, E. J., & Moss, A. (2016). CMB constraints on cosmic strings and superstrings. Physical Review D - Particles, Fields, Gravitation and Cosmology, 93(12), Article 123503. https://doi.org/10.1103/PhysRevD.93.123503

We present the first complete MCMC analysis of cosmological models with evolving cosmic (super)string networks, using the Unconnected Segment Model in the unequal-time correlator formalism. For ordinary cosmic string networks, we derive joint constra... Read More about CMB constraints on cosmic strings and superstrings.

Tension between the power spectrum of density perturbations measured on large and small scales (2015)
Journal Article
Battye, R., Charnock, T., & Moss, A. (2015). Tension between the power spectrum of density perturbations measured on large and small scales. Physical Review D, 91(10), Article 103508. https://doi.org/10.1103/PhysRevD.91.103508

There is a tension between measurements of the amplitude of the power spectrum of density perturbations inferred using the cosmic microwave background (CMB) and directly measured by large-scale structure (LSS) on smaller scales. We show that this ten... Read More about Tension between the power spectrum of density perturbations measured on large and small scales.

Did BICEP2 See Vector Modes? First B-Mode Constraints on Cosmic Defects (2014)
Journal Article
Moss, A., & Pogosian, L. (2014). Did BICEP2 See Vector Modes? First B-Mode Constraints on Cosmic Defects. Physical Review Letters, 112(17), Article 171302. https://doi.org/10.1103/PhysRevLett.112.171302

Scaling networks of cosmic defects, such as strings and textures, actively generate scalar, vector, and tensor metric perturbations throughout the history of the Universe. In particular, vector modes sourced by defects are an efficient source of the... Read More about Did BICEP2 See Vector Modes? First B-Mode Constraints on Cosmic Defects.
