Addressing Synchrotron Challenges for CMB Observations: ELFS-SA Collaboration for Robust Foreground Removal
E. de la Hoz, A. Mennella, K. Arnold +17
Upcoming cosmic microwave background (CMB) experiments aim to detect primordial gravitational waves with unprecedented sensitivity. Effective foreground removal is essential to avo…
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…
The European Low Frequency Survey on the Simons Array
Aniello Mennella, Kam Arnold, Susanna Azzoni +18
In this paper we present the European Low Frequency Survey (ELFS), a project that will enable foregrounds-free measurements of the primordial -mode polarization and a detection…
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…
