Euclid: Field-level inference of primordial non-Gaussianity and cosmic initial conditions
A. Andrews, J. Jasche, G. Lavaux +147
A primary target of the \Euclid space mission is to constrain early-universe physics by searching for deviations from a primordial Gaussian random field. A significant detection of…
Multi-dimensional optimisation of the scanning strategy for the LiteBIRD space mission
Y. Takase, L. Vacher, H. Ishino +105
Large angular scale surveys in the absence of atmosphere are essential for measuring the primordial -mode power spectrum of the Cosmic Microwave Background (CMB). Since this pro…
Requirements on the gain calibration for LiteBIRD polarisation data with blind component separation
F. Carralot, A. Carones, N. Krachmalnicoff +106
Future cosmic microwave background (CMB) experiments are primarily targeting a detection of the primordial -mode polarisation. The faintness of this signal requires exquisite co…
Conversations in the dark: cross-correlating birefringence and LSS to constrain axions
S. Arcari, N. Bartolo, A. Greco +3
Unveiling the dark sector of the Universe is one of the leading efforts in theoretical physics. Among the many models proposed, axions and axion-like particles stand out due to the…
LiteBIRD Science Goals and Forecasts. Mapping the Hot Gas in the Universe
M. Remazeilles, M. Douspis, J. A. Rubiño-MartÃn +104
We assess the capabilities of the LiteBIRD mission to map the hot gas distribution in the Universe through the thermal Sunyaev-Zeldovich (SZ) effect. Our analysis relies on compreh…
A New Solution for the Observed Isotropic Cosmic Birefringence Angle and its Implications for the Anisotropic Counterpart through a Boltzmann Approach
Alessandro Greco, Nicola Bartolo, Alessandro Gruppuso
Cosmic Birefringence (CB) is a phenomenon in which the polarization of the Cosmic Microwave Background (CMB) radiation is rotated as it travels through space due to the coupling be…
