Dynamical response to supernova-induced gas removal in spiral galaxies with dark matter halo
Hiroko Koyama, Masahiro Nagashima, Takayuki Kakehata +1
We investigate the dynamical response, in terms of disc size and rotation velocity, to mass loss by supernovae in the evolution of spiral galaxies. A thin baryonic disc having the…
The origin of globular cluster systems from cosmological simulations
K. Bekki, H. Yahagi, M. Nagashima +1
We investigate the structural, kinematical, and chemical properties of globular cluster systems (GCSs) in galaxies of different Hubble types in a self-consistent manner based on hi…
Star formation history of galaxies from z=0 to z=0.7 A backward approach to the evolution of star-forming galaxies
V. Buat, S. Boissier, D. Burgarella +6
We investigate whether the mean star formation activity of star-forming galaxies from z=0 to z=0.7 in the GOODS-S field can be reproduced by simple evolution models of these system…
Formation of the Galactic globular clusters with He-rich stars in low-mass halos virialized at high redshift
K. Bekki, H. Yahagi, M. Nagashima +1
Recent observations have reported that the Galactic globular clusters (GCs) with unusually extended horizontal-branch (EHB) morphologies show a significantly lower velocity dispers…
Lyman Alpha Emitters in the Hierarchically Clustering Galaxy Formation
Masakazu A. R. Kobayashi, Tomonori Totani, Masahiro Nagashima
We present a new theoretical model for the luminosity functions (LFs) of Lyman alpha (Lya) emitting galaxies in the framework of hierarchical galaxy formation. We extend a semi-ana…
The Effect of Orbital Eccentricity on Gravitational Wave Background Radiation from Supermassive Black Hole Binaries
Motohiro Enoki, Masahiro Nagashima
A compact binary in an eccentric orbit radiates gravitational waves (GWs) at all integer harmonics of its orbital frequency. In this study, we investigate the effect of orbital ecc…
