Magnetohydrodynamics Simulations of the First Galaxy Formation

[ Poster ]

Huai-Hsuan Chiu (ASIAA/NTU), Ke-Jung Chen (ASIAA)

With the modern large telescopes, astronomers can peek into the universe and study its large scale formation. At the kiloparsec scales, the magnetic field plays an important role in the star formation and galaxy evolution. In this poster, we study how the magnetic field influences on star formation with cosmological simulations. To achieve this goal, we use the N-body hydro code GIZMO (Philip F. Hopkins.,2018) to perform the cosmological simulation with 140 million particles including dark matter, gas, and star. The initial conditions of our simulations are generated by the MUSIC(Oliver Hahn and Tom Abel.,2011) code, which takes the cosmological parameters from the WMAP data and use ROCKSTAR (Peter S. Behroozi, 2013) code to search for dark matter halos. We discuss the results and compare them with previous models and provide new predictions for future observatories.
