Tamura, Yoichi

Tamura is a co-author of the study 'Bound star clusters observed in a lensed galaxy 460 Myr after the Big Bang', published in Nature. The research focuses on observing five star clusters located in a region smaller than 70 parsec of an intrinsically UV faint galaxy, which is thought to drive the reionization of the universe. Despite uncertainties inherent to the lensing model, these star clusters exhibit minimal dust attenuation and low metallicity, ages younger than 50 Myr and intrinsic masses of less than 106 M₎. Their lensing-corrected sizes are approximately 1 pc, resulting in stellar surface densities near 105 M₎/pc2. The authors conclude that star cluster formation and feedback likely contributed to shaping the properties of galaxies during the epoch of reionization.

Contradictions

95%

Examples:

  • The authors suggest that these star clusters are gravitationally bound stellar systems, i.e., proto-globular clusters (proto-GCs). Yet, they acknowledge that there are uncertainties inherent to the lensing model.
  • The author states that the galaxy is intrinsically UV faint and in the range of those now thought to drive the reionization of the universe. However, they also report observing five star clusters with minimal dust attenuation and low metallicity.
