Title: An inhomogeneous universe as a possible interpretation of DESI BAO result
Speaker: Prof. Toshi Futamase (Tohoku University)
Venue: SC427, Science Building 3, NYCU
Abstract:
In 2024, DESI (Dark Energy Spectroscopic Instrument) reported the time variation of the Hubble parameter based on BAO (Baryon Acoustic Oscillation) observations, showing that it contradicts the predictions of standard cosmology. One interpretation of these discrepancies is to introduce an appropriate time variation to dark energy without changing the cosmological model. We do not take this point of view, but take a completely different point of view that is based on observations from infrared galaxy surveys, indicating that the Milky Way galaxy is located in a low-density region on a 300 Mpc scale.
In this talk, I will begin with a brief explanation of DESI, BAO, and the Hubble tension, and then consider the effect of inhomogeneous distribution of matter on the cosmological expansion. I will explain how this effect allows us to interpret the DESI results and simultaneously explain the Hubble tension.

Affiliation: Space Telescope Science Institute (STScI)
Place: Science Building III SC157
Abstract:
The superb capabilities of the James Webb Space Telescope (JWST) have extended our view to the ultra-high-redshift universe (z > 12). Among numerous scientific discoveries enabled by JWST, some early deep extragalactic observations have unexpectedly revealed an abundance of massive galaxies, presenting significant challenges to conventional galaxy formation models. To address this cosmic puzzle, we utilize some well-established galaxy formation models in conjunction with state-of-the-art cosmological simulations to seek understanding of physical mechanisms that enabled extremely rapid star formation activities in the early universe. We investigated and quantified the impact of various sources of uncertainty, including a potentially evolving mass-to-light ratio driven by changes in the IMF, underestimated field-to-field variance, and significant uncertainties in photometric redshifts, among others. Our study also examines the number density of halo populations during this epoch, alongside the gas cooling rates and star formation efficiencies of galaxies. I will also present new simulated results for various alternative star formation and stellar feedback models and discuss the essential conditions required to reproduce the observed ultra-high-redshift galaxy populations.
