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.

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.
