Spin Parity of Spiral Galaxies VI -- A Search for Dynamical Memory in the Spin Distribution of Galaxies in HSC WIDE Survey Regions
Masanori Iye, Masafumi Yagi
We analyzed the distribution of spin parity in spiral galaxies using the HSC DR2 data. The spiral winding parity of disk galaxies, observed as S-spiral or Z-spiral projected onto t…

Re-recognized universality of Kozai oscillation on three-body dynamics
Masanori Iye, Takashi Ito
In 1962, Yoshihide Kozai reported his findings on the secular dynamics of asteroids moving in orbits with high inclination and eccentricity. In contrast to the classic understandin…

Spin Parity of Spiral Galaxies IV -- Differential Reddening of Globular Cluster Systems of Nearby Spiral Galaxies
Masanori Iye, Masafumi Yagi
The northwest side of the disk of M31 is known to be the near side because of the differential reddening of globular clusters found from their photographic photometry. This paper r…
