Dynamical formation of Gaia neutron star binaries in star clusters as a phase-dependent process
Ryutaro Iwakura, Long Wang, Ataru Tanikawa +3
Gaia has discovered dormant compact-object binaries in which the compact object shows no observable interaction with its luminous companion. These systems, hereafter Gaia BHs and G…
SIRIUS Project: Dynamical Evolution of Primordial Binaries during Star Cluster Formation
Naoto Harada, Michiko S. Fujii, Takayuki R. Saitoh +1
Binary populations are closely linked to the star formation process; however, their primordial properties can be changed by subsequent dynamical interactions within their natal clu…
SIRIUS: The relation between the diversity of dwarf galaxies and their formation histories
Chi-Hong Lin, Michiko S Fujii, Takayuki R Saitoh +1
Low-mass dwarf galaxies () are fundamental cosmological building blocks, yet the physical processes driving their structural diversity remain…
SIRIUS: Dark matter cusp evolution in dense dwarf galaxies
Katsuhiro Kaneko, Takayuki R. Saitoh, Yutaka Hirai +1
Dwarf galaxies have a wide variety of structures, such as dark matter (DM) distribution, stellar-to-halo mass ratio, and stellar density. Recent high-resolution simulations have sh…
Nitrogen enhancement of GN-z11 by metal pollution from supermassive stars
Sho Ebihara, Michiko S. Fujii, Takayuki R. Saitoh +4
Spectroscopic observations by the James Webb Space Telescope (JWST) have revealed young, compact, high-redshift () galaxies with high nitrogen-to-oxygen (N/O) ratios. GN-z11 at…
