LiteBIRD Science Goals and Forecasts: constraining isotropic cosmic birefringence
E. de la Hoz, P. Diego-Palazuelos, J. Errard +112
Cosmic birefringence (CB) is the rotation of the photons' linear polarisation plane during propagation. Such an effect is a tracer of parity-violating extensions of standard electr…

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…

Constraining Ultralight ALP Dark Matter in Light of Cosmic Birefringence
Dongdong Zhang, Elisa G. M. Ferreira, Ippei Obata +1
Cosmic birefringence, the observed rotation of the polarization plane of the cosmic microwave background (CMB), serves as a compelling probe for parity-violating physics beyond the…
