Varying fundamental constants principal component analysis: additional hints about the Hubble tension
Varying fundamental constants (VFC; eg the fine-structure constant, αEM) can arise in
numerous extended cosmologies. Through their effect on the decoupling of baryons and …

Cosmic Birefringence from the Planck Data Release 4
We search for the signature of parity-violating physics in the cosmic microwave background,
called cosmic birefringence, using the Planck data release 4. We initially find a birefringence …

Small-scale clumping at recombination and the Hubble tension
Despite the success of the standard Λ CDM model of cosmology, recent data improvements
have made tensions emerge between low-and high-redshift observables, most importantly …

Consequences of neutrino self-interactions for weak decoupling and big bang nucleosynthesis
We calculate and discuss the implications of neutrino self-interactions for the physics of
