DESCRIPTION:Department of Physics Colloquium\, Professor Maria Dainotti\, N
 ational Astronomical Observatory of Japan\n\nTitle:  Probing the possible 
 redshift evolution of the Hubble constant with SNe Ia and future perspecti
 ves with Gamma-Ray Bursts\n\nHost:  Andre LeClair\n\nAbstract:  The persis
 tent Hubble constant tension motivates investigating whether H₀ may evol
 ve with redshift. I will present a 20-bin analysis of the Master Type Ia S
 upernova Sample within the flat ΛCDM model\, testing the inferred H₀ ev
 olution using logarithmic and power-law parameterizations. While both form
 s behave similarly up to the Cosmic Microwave Background epoch\, they dive
 rge increasingly toward Big Bang Nucleosynthesis and inflationary scales\,
  exhibiting qualitatively different high-redshift limits. I will discuss t
 he implications and limitations of these results and future work combining
  Type Ia supernovae with Gamma-Ray Bursts to extend these tests over a sub
 stantially wider redshift range.
