FOSSIL: A future mission for CMB spectral distortion measurements
N. Aghanim, B. Maffei, J. Aumont +96
We present FOSSIL, a proposed space mission which is designed to deliver unprecedented absolute spectroscopic measurements of the sky intensity over a broad frequency range (50GHz…
Peering Beyond the Veil of Last Scattering: A View of the Universe with CMB Spectral Distortions
Bryce Cyr, Nabila Aghanim, Ethan Baker +37
The frequency spectrum of the cosmic microwave background is the most precise blackbody ever measured in nature, with deviations constrained at the level of almost one part per mil…
Distinguishing Distance Duality breaking models using electromagnetic and gravitational waves measurements
Chiara De Leo, Matteo Martinelli, Rocco D'Agostino +2
Several assumptions at the foundation of the standard cosmological model have as a direct consequence a specific relation between cosmological distances, known as the distance dual…
Cosmic strings and other topological defects in nonscaling regimes
R. P. L. Azevedo, C. J. A. P. Martins
Cosmic strings are topological defects possibly formed in the early Universe, which may be observable due to their gravitational effects on the cosmic microwave background radiatio…
Constraining spatial variations of the fine structure constant using clusters of galaxies and Planck data
I. de Martino, C. J. A. P. Martins, H. Ebeling +1
We propose an improved methodology to constrain spatial variations of the fine structure constant using clusters of galaxies. We use the {\it Planck} 2013 data to measure the therm…
Constraints on the CMB temperature redshift dependence from SZ and distance measurements
A. Avgoustidis, G. Luzzi, C. J. A. P. Martins +1
The relation between redshift and the CMB temperature, is a key prediction of standard cosmology, but is violated in many non-standard models. Constraining po…
Astrophysical Probes of Fundamental Physics
C. J. A. P. Martins
The dramatic confrontation between new observations and theories of the early and recent universe makes cosmology one of the most rapidly advancing fields in the physical sciences.…
