Internal r-process abundance spread of M15 and a single stellar population model
Yuta Tarumi, Naoki Yoshida, Shigeki Inoue
The member stars in globular cluster M15 show a substantial spread in the abundances of r-process elements. We argue that a rare and prolific r-process event enriched the natal clo…
Detecting preheating in proto-clusters with Lyman- Forest Tomography
Robin Kooistra, Shigeki Inoue, Khee-Gan Lee +2
Studies of low redshift galaxy clusters suggest the intra-cluster medium (ICM) has experienced non-gravitational heating during the formation phase of the clusters. Using simple ph…
Instability analysis for spiral arms of local galaxies: M51, NGC3627 and NGC628
Shigeki Inoue, Toshinobu Takagi, Atsushi Miyazaki +3
We investigate dynamical states of grand-design spiral arms in three local galaxies: M51, NGC3627 and NGC628. Based on linear perturbation analysis considering multiple components…
Fragmentation of ring galaxies and transformation to clumpy galaxies
Shigeki Inoue, Naoki Yoshida, Lars Hernquist
We study the fragmentation of collisional ring galaxies (CRGs) using a linear perturbation analysis that computes the physical conditions of gravitational instability, as determine…
Capturing the inside-out quenching by black holes with far-infrared atomic line ratios
Shigeki Inoue, Hiroshi Matsuo, Naoki Yoshida +2
We propose to use relative strengths of far-infrared fine structure lines from galaxies to characterise early phases of the inside-out quenching by massive black holes (BHs). The B…
