Cosmological simulations of Milky Way-sized galaxies. Their haloes ware taken from the Aquarius project. We have simulated two Aquarius galaxies: Aq-C and Aq-D. They form discs and in their centre they have pseudobulges instead of classical ones.

Aq-C:
This movie shows gas (upper) and stellar (lower) distributions in a 50 kpc/h box in physical coordinates centred on
the main progenitor.
The viewing angles are chosen to be face-on at redshfit 0 in the left panels and edge-on in the rigth panels.
Aq-D:
Same as above movie but for Aq-D.
A cosmological simulation of disc galaxy formation in a LCDM universe. The initial condition is the same as used in Okamoto et al. 2005 but now we consider growing black holes and associated AGN feedback. We assume accretion discs can produce strong jets only when accretion rate onto black holes is much lower then the Eddington rate, i.e. only RIAFs produce strong radio jets.

This movie shows stellar (left) and gas (right) distributions in a 3 Mpc/h comoving box centred on the main progenitor (upper panels) and in a 50 kpc/h box in physical coordinates (lower panels), where brightness represents three dimensional density.The circles in each panel indicate the position of the black hole particles and their radii are proportional to the log of the black hole masses.

A cosmological simulation of spiral galaxy formation in a LCDM universe. The simulation box size is 35.325 Mpc/h and we put gas and high-resolution dark matter particles into the region where an isolated dark halo forms. This simulation includes the metallicity dependent radiative cooling, chemical enrichment of the gas by Type Ia and II SNe, and the non-instantaneous feedback together with a multi-phase description for the ISM.

Stars
This movie shows stellar distribution in a 100 kpc/h cube in physical coordinates. The viewing angles are fixed to be face-on (left) and edge-on (right) at z = 0. Redshift and comoving box sizes are shown in the movies. Colors are coded by projected densities.
Gas
The same as the above movie but for gas.
Dark matter
Dark matter distribution in a 200 kpc/h box in physical coordinates, which is twice as large as those for baryons. The viewing angle is chosen to be edge-on for the galaxy at z = 0.
Wanna see both of stars and gas at the same time?
