Galaxy Formation in the Presence of Ultraviolet Background Radiation Field --- A Simulation by Radiation-SPH ---
We studied galaxy formation with Radiation-SPH simulations in order to find the effects of UVB field on the star formation in the forming galaxies. We find the UVB radiation field can delay the star formation in protogalactic clouds, especially at low redshift (z < 2). This result suggests that galaxies formed at lower redshift tend to be late type galaxies and early type galaxies tend to be formed at higher redshift.
