The Aquila comparison Project: The Effects of Feedback and Numerical Methods on Simulations of Galaxy Formation
C. Scannapieco, M. Wadepuhl, O. H. Parry +20
We compare the results of thirteen cosmological gasdynamical codes used to simulate the formation of a galaxy in the LCDM structure formation paradigm. The various runs differ in t…
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…
The Baryons in the Milky Way Satellites
Owen H. Parry, Vincent R. Eke, Carlos S. Frenk +1
We investigate the formation and evolution of satellite galaxies using smoothed particle hydrodynamics (SPH) simulations of a Milky Way(MW)-like system, focussing on the best resol…
ARGOT: Accelerated radiative transfer on grids using oct-tree
Takashi Okamoto, Kohji Yoshikawa, Masayuki Umemura
We present two types of numerical prescriptions that accelerate the radiative transfer calculation around point sources within a three-dimensional Cartesian grid by using the oct-t…
N-body simulation for self-gravitating collisional systems with a new SIMD instruction set extension to the x86 architecture, Advanced Vector eXtensions
Ataru Tanikawa, Kohji Yoshikawa, Takashi Okamoto +1
We present a high-performance N-body code for self-gravitating collisional systems accelerated with the aid of a new SIMD instruction set extension of the x86 architecture: Advance…
Lyman-alpha Emitters in Cosmological Simulations I: Lyman-alpha Escape Fraction and Statistical Properties at z=3.1
Ikkoh Shimizu, Naoki Yoshida, Takashi Okamoto
We use very large cosmological Smoothed-Particle-Hydrodynamics simulations to study the properties of high redshift Lyman-alpha emitters (LAEs). We identify star-forming galaxies a…
