DESCRIPTION:The Chern–Simons coupling between the scalar field in early 
 dark energy (EDE) models and CMB photons is regarded as a plausible mechan
 ism for generating cosmic birefringence.  Recent data from the SPIDER and
  Atacama Cosmology Telescope (ACT) deliver EB measurements at different mu
 ltipole moments than those previously achieved by Planck\, while DESI and 
 PantheonPlus datasets provide new and stringent constraints on the late-ti
 me expansion history.\n\nhttps://indico.ibs.re.kr/event/1392/
