Dual-disk galaxies and thermal states of circumgalactic medium
Masafumi Noguchi
Disk galaxies often have dual-disk structures composed of thin disks and thick disks. Recent observations reveal that such duality is ubiquitous across broad galaxy mass and cosmic…
Feedback shaped the galaxy morphological sequence in presence of mergers
Masafumi Noguchi
Bulges and disks are major structural components that define galaxy morphology. The mass ratios of bulges and disks increase statistically with the galaxy mass, with the high-mass…
Anatomy of galactic star formation history: Roles of different modes of gas accretion, feedback, and recycling
Masafumi Noguchi
We investigate how the diverse star formation histories observed across galaxy masses emerged using models that evolve under gas accretion from host halos. They also include ejecti…
Formation of galactic bulges from the cold gas filaments in high-redshift dark matter halos
Masafumi Noguchi
Formation process(es) of galactic bulges are not yet clarified although several mechanisms have been proposed. In a previous study, we suggested one possibility that galactic bulge…
Fundamental mechanism of the creation of chemical bimodality in the Milky Way disc in the cold accretion theory
Masafumi Noguchi
Chemical bimodality of the Milky Way (MW) disc stars constitutes one of the most remarkable properties of MW. The cold accretion theory for the cosmological gas accretion provides…
Structural diversity of disc galaxies originating in the cold gas inflow from cosmic webs
Masafumi Noguchi
Disc galaxies show a large morphological diversity with varying contribution of three major structural components; thin discs, thick discs, and central bulges. Dominance of bulges…
