An axion can couple to photons in a parity-violating manner. Through this coupling, variations in the axion field induce a rotation of the linear polarization plane of photons, i.e., cosmic birefringence. Recently, a hint of isotropic cosmic birefringence has been reported in the EB cross-correlation of the CMB data. In this talk, I will explain the relation between the EB signal and cosmic...
The fundamental nature of dark matter (DM) so far eludes direct detection experiments, but it has left its imprint in the cosmic microwave background (CMB) and large-scale structure (LSS) of the Universe. I will present new results demonstrating how the discrepancy in the amplitude of density fluctuations between CMB and LSS observations (galaxy clustering, weak lensing and Lyman-alpha forest)...
The frequency spectrum of the cosmic microwave background (CMB) remains a valuable and nearly untapped resource of cosmological data. By searching for departures from a perfect blackbody, it is possible to sensitively constrain the thermal history of the universe back to redshifts roughly three orders of magnitude higher than with CMB temperature anisotropies. In this talk, I will review the...
