Biography

Yuto Minami is a researcher in particle physics experiments at the RCNP, Osaka Univ. His research interests include particle physics and cosmology. He analyzes observed data from a neutrinoless double beta decay experiment and studies readout systems for next-generation detectors. He has been studying the calibration of polarization-sensitive detectors for cosmic microwave background (CMB) experiments and has been developing a foreground removal method for CMB experiments.

Methodological note on patchy reionization and anisotropic cosmic birefringence

I wrote a methodological note on how to interpret anisotropic cosmic birefringence constraints when an effective contribution from patchy reionization is present. The note emphasizes that current anisotropic cosmic birefringence constraints should be read as constraints on the total birefringence power, rather than automatically as limits on a single ALP-induced fluctuation component.
