Dark energy constraints and correlations with systematics from CFHTLS weak lensing, SNLS supernovae Ia and WMAP5
M. Kilbinger, K. Benabed, J. Guy +15
We combine measurements of weak gravitational lensing from the CFHTLS-Wide survey, supernovae Ia from CFHT SNLS and CMB anisotropies from WMAP5 to obtain joint constraints on cosmo…
The radial alignment of dark matter subhalos: from simulations to observations
Alexander Knebe, Hideki Yahagi, Hiroyuki Kase +2
We explore the radial alignment of subhalos in 2-dimensional projections of cosmological simulations. While most other recent studies focussed on quantifying the signal utilizing t…
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…
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…
On the Origin of Mass--Metallicity Relations, Blue Tilts, and Scaling Relations for Metal-poor Globular Cluster Systems
K. Bekki, H. Yahagi, D. A. Forbes
We investigate formation processes and physical properties of globular cluster systems (GCSs) in galaxies based on high-resolution cosmological simulations with globular clusters.…
On spatial distributions of old globular clusters in clusters of galaxies
Kenji Bekki, Hideki Yahagi
We investigate structural properties of old, metal-poor globular clusters (GCs) formed at high redshifts (z>6) and located inside and outside virialized galaxy-scale halos in clust…
