This week’s post covers the resurgence of cosmic triangles in the context of the Hubble tension, how to use redshift drift to probe dark energy in a model-independent way, and how to self-calibrate polarization efficiency in CMB experiments. Enjoy the read and have a nice weekend!

This week’s entry looks at the first measurement of the cosmic birefringence angle from the CMB, the generation of large primordial non-Gaussianity from Higgs-induced modulated reheating, and a quasi-model-independent inference of the Hubble constant and the late-time expansion. Happy Thanksgiving to my American readers!
