Origin of multiple nuclei in ultraluminous infrared galaxies
Hidenori Matsui, Takayuki R. Saitoh, Junichiro Makino +6
Ultraluminous infrared galaxies (ULIRGs) with multiple () nuclei are frequently observed. It has been suggested that these nuclei are produced by multiple major mergers of g…
Natures of a clump-origin bulge: a pseudobulge-like but old metal-rich bulge
Shigeki Inoue, Takayuki R. Saitoh
Bulges in spiral galaxies have been supposed to be classified into two types: classical bulges or pseudobulges. Classical bulges are thought to form by galactic merger with bursty…
Shallowed cusp slope of dark matter in disc galaxy formation through clump clusters
Shigeki Inoue, Takayuki R. Saitoh
Cusp-core problem is a controversial problem on galactic dark matter haloes. Cosmological N-body simulations has demonstrated that galactic dark matter haloes have a cuspy density…
Nuclear Star-Forming Ring of the Milky Way: Simulations
Sungsoo S. Kim, Takayuki R. Saitoh, Myoungwon Jeon +3
We present hydrodynamic simulations of gas clouds in the central kpc region of the Milky Way that is modeled with a three-dimensional bar potential. Our simulations consider realis…
Interplay between Stellar Spirals and the ISM in Galactic Disks
Keiichi Wada, Junichi Baba, Takayuki R. Saitoh
We propose a new dynamical picture of galactic stellar and gas spirals, based on hydrodynamic simulations in a `live' stellar disk. We focus especially on spiral structures excited…
Shock-induced star cluster formation in colliding galaxies
Takayuki R. Saitoh, Hiroshi Daisaka, Eiichiro Kokubo +5
We studied the formation process of star clusters using high-resolution N-body/smoothed particle hydrodynamcs simulations of colliding galaxies. The total number of particles is 1.…
