A chemically etched D-band waveguide orthomode transducer for CMB measurements

E. Manzan, A. Mennella, F. Cavaliere +21

This study presents a prototype D-band waveguide orthomode transducer (OMT) fabricated using chemically etched brass platelets. This method offers a fast, cost-effective, and scala…

Measuring the CMB spectral distortions with COSMO: the multi-mode antenna system

E. Manzan, L. Albano, C. Franceschet +29

In this work, we present the design and manufacturing of the two multi-mode antenna arrays of the COSMO experiment and the preliminary beam pattern measurements of their fundamenta…

Observing galaxy clusters and the cosmic web through the Sunyaev Zel'dovich effect with MISTRAL

E. S. Battistelli, E. Barbavara, P. de Bernardis +33

Galaxy clusters and surrounding medium, can be studied using X-ray bremsstrahlung emission and Sunyaev Zel'dovich (SZ) effect. Both astrophysical probes, sample the same environmen…

Total power horn-coupled 150 GHz LEKID array for space applications

A. Paiella, A. Coppolecchia, P. de Bernardis +17

We have developed two arrays of lumped element kinetic inductance detectors working in the D-band, and optimised for the low radiative background conditions of a satellite mission…

A precise numerical estimation of the magnetic field generated around recombination

Christian Fidler, Guido Pettinari, Cyril Pitrou

We investigate the generation of magnetic fields from non-linear effects around recombination. As tight-coupling is gradually lost when approaching , the velocity dif…

Impact of polarisation on the intrinsic CMB bispectrum

Guido W. Pettinari, Christian Fidler, Robert Crittenden +3

We compute the bispectrum induced in the cosmic microwave background (CMB) temperature and polarisation by the evolution of the primordial density perturbations using the second-or…

The intrinsic bispectrum of the Cosmic Microwave Background [PhD thesis]

Guido Walter Pettinari

The CMB bispectrum is a potential window on exciting new physics, as it is sensitive to the non-Gaussian features in the primordial fluctuations, the same fluctuations that evolved…

The intrinsic B-mode polarisation of the Cosmic Microwave Background

Christian Fidler, Guido W. Pettinari, Martin Beneke +3

We estimate the B-polarisation induced in the Cosmic Microwave Background by the non-linear evolution of density perturbations. Using the second-order Boltzmann code SONG, our anal…

Spectral distortions in the cosmic microwave background polarization

Sebastien Renaux-Petel, Christian Fidler, Cyril Pitrou +1

We compute the spectral distortions of the Cosmic Microwave Background (CMB) polarization induced by non-linear effects in the Compton interactions between CMB photons and cold int…

The intrinsic bispectrum of the Cosmic Microwave Background

Guido W. Pettinari, Christian Fidler, Robert Crittenden +2

We develop a new, efficient code for solving the second-order Einstein-Boltzmann equations, and use it to estimate the intrinsic CMB non-Gaussianity arising from the non-linear evo…

Orthogonal non-Gaussianity in DBI Galileon: prospect for Planck polarisation and post-Planck experiments

Kazuya Koyama, Guido Walter Pettinari, Shuntaro Mizuno +1

In this note, we study cosmic microwave background (CMB) constraints on primordial non-Gaussianity in DBI galileon models in which an induced gravity term is added to the Dirac-Bor…

Using galaxy pairs as cosmological tracers

Alicia Bueno Belloso, Guido Walter Pettinari, Nikolai Meures +1

The Alcock-Paczynski (AP) effect uses the fact that, when analyzed with the correct geometry, we should observe structure that is statistically isotropic in the Universe. For struc…

On the Evidence for Axion-like Particles from Active Galactic Nuclei

Guido Walter Pettinari, Robert Crittenden

Burrage, Davis, and Shaw recently suggested exploiting the correlations between high and low energy luminosities of astrophysical objects to probe possible mixing between photons a…
