Ongoing assembly of massive galaxies by major merging in large groups and clusters from the SDSS
general surveys
2014/12/23
We investigate the incidence of major mergers creating massive (Mstar > 1011 M⊙) galaxies in present-day (z≤ 0.12) groups and clusters. Using a volume-limited sample of 845 groups with dark matter hal...
Aims. The goal of this work is to infer the star formation properties and the mass assembly process of high redshift (0.3 ≤ z < 2.5) galaxies from their IR emission using the 24 μm band of MIPS-Spitze...
Dark Matter Halos: Assembly, Clustering and Sub-halo Accretion
Dark matter Galaxy formation Halos
2014/12/9
I carried out systematic studies on the assembly history of dark matter halos, using numerical simulations and semi-analytical methods. First, I look into dark halo mass assembly history. I confirmed ...
The Assembly of Galaxies Over Cosmic Time

2014/12/9
To Understand how galaxies were assembled across the cosmic time remains one of the most outstanding questions in astronomy. The core of this question is how today's Hubble Sequence, namely the differ...

2011/9/26
We investigate the properties of satellite galaxies that surround isolated hosts within the redshift range 0.01 < z < 0.15, using data taken as part of the Galaxy And Mass Assembly survey. Making use ...
The dark matter assembly of the Local Group in constrained cosmological simulations of a LambdaCDM universe
galaxies: haloes cosmology: theory methods: N-body simulations
2011/9/26
We make detailed theoretical predictions for the assembly properties of the Local Group (LG) in the standard LambdaCDM cosmological model. We use three cosmological N-body dark matter simulations from...
