Constraints on cosmological birefringence energy dependence from CMB polarization data

Journal Article Gubitosi, G. ; Paci, F., E-mail: giulia.gubitosi@roma1.infn.it, E-mail: fpaci@sissa.it - Journal of Cosmology and Astroparticle Physics

We study the possibility of constraining the energy dependence of cosmological birefringence by using CMB polarization data. We consider four possible behaviors, characteristic of different theoretical scenarios: energy-independent birefringence motivated by Chern-Simons interactions of the electromagnetic field, linear energy dependence motivated by a 'Weyl' interaction of the electromagnetic field, quadratic energy dependence, motivated by quantum gravity modifications of low-energy electrodynamics, and inverse quadratic dependence, motivated by Faraday rotation generated by primordial magnetic fields. We constrain the parameters associated to each kind of dependence and use our results to give constraints on the models mentioned. We forecast the sensitivity that Planckmore »« less

Cosmological birefringence constraints from CMB and astrophysical polarization data

Journal Article Galaverni, M. ; Gubitosi, G. ; Paci, F. ; ... - Journal of Cosmology and Astroparticle Physics

Cosmological birefringence is a rotation of the polarization plane of photons coming from sources of astrophysical and cosmological origin. The rotation can also depend on the energy of the photons and not only on the distance of the source and on the cosmological evolution of the underlying theoretical model. In this work, we constrain few selected models for cosmological birefringence, combining CMB and astrophysical data at radio, optical, X and γ wavelengths, taking into account the specific energy and distance dependences.

Constraints on the neutrino parameters by future cosmological 21 cm line and precise CMB polarization observations

Journal Article Oyama, Yoshihiko ; Kohri, Kazunori ; Hazumi, Masashi - Journal of Cosmology and Astroparticle Physics

Observations of the 21 cm line radiation coming from the epoch of reionization have a great capacity to study the cosmological growth of the Universe. Besides, CMB polarization produced by gravitational lensing has a large amount of information about the growth of matter fluctuations at late time. In this paper, we investigate their sensitivities to the impact of neutrino property on the growth of density fluctuations, such as the total neutrino mass, the effective number of neutrino species (extra radiation), and the neutrino mass hierarchy. We show that by combining a precise CMB polarization observation such as Simons Array withmore »« less

CMB polarization systematics due to beam asymmetry: Impact on cosmological birefringence

Journal Article Miller, N J ; Shimon, M ; Keating, B G - Physical Review. D, Particles Fields

The standard cosmological model is assumed to respect parity symmetry. Under this assumption the cross correlations of the cosmic microwave background's temperature anisotropy and 'gradient'-like polarization, with the 'curl'-like polarization, identically vanish over the full sky. However, extensions of the standard model which allow for light scalar field or axion coupling to the electromagnetic field, or coupling to the Riemann gravitational field strength, as well as other modifications of field theories, may induce a rotation of the cosmic microwave background polarization plane on cosmological scales and manifest itself as nonvanishing TB and EB cross correlations. Recently, the degree of paritymore »« less

On the impact of large angle CMB polarization data on cosmological parameters

Journal Article Lattanzi, Massimiliano ; Mandolesi, Nazzareno ; Natoli, Paolo ; ... - Journal of Cosmology and Astroparticle Physics

We study the impact of the large-angle CMB polarization datasets publicly released by the WMAP and Planck satellites on the estimation of cosmological parameters of the ΛCDM model. To complement large-angle polarization, we consider the high resolution (or 'high-ℓ') CMB datasets from either WMAP or Planck as well as CMB lensing as traced by Planck 's measured four point correlation function. In the case of WMAP, we compute the large-angle polarization likelihood starting over from low resolution frequency maps and their covariance matrices, and perform our own foreground mitigation technique, which includes as a possible alternative Planck 353 GHz datamore »« less
