題名
SU(N)-natural inflation

概要
Inflation is widely accepted as a part of the standard cosmology, while its mechanism is still unknown. Among many proposed models, natural inflation have attracted much attention, because this class of inflation models offers not only natural realization of inflation but also rich phenomenology such as magnetogenesis, baryogenesis, gravitational wave production, etc. In this context, we constructed a new model where the axionic inflation is coupled to general SU(N) gauge fields. After briefly reviewing natural inflation, I will introduce our model and discuss recent developments and open questions.

題名
IGM Tomography with Subaru/HSC: implications to reionization and SMBH

概要
The art of cosmography, i.e. map-making of the Universe, is essential for the progress in astronomy. In this talk, I present a new technique to reconstruct a large-scale structure of the intergalactic medium (IGM) using a unique combination of the narrow-band filters with Subaru/HSC. The technique is applicable to high redshifts across z~4-6 and is perfectly suited to examine the ionizing radiation and the gaseous environment of galaxies and quasars. I demonstrate the method using the public release of HSC data and present the first co-spatial, large-scale map of the Lyman-alpha emitters and the IGM in the COSMOS field at z~5. I also discuss the potential applications of IGM tomography and the implications for our understanding of reionization and the growth of supermassive black holes.
