What the Formation of the First Stars Left in its Wake

PDF Version Also Available for Download.

Description

The formation of the first stars marked a crucial transition in the formation of structure in the universe. Through their feedback effects, which include ionization by their radiation and the supernovae or black holes formed at the end of their lives, they were able to influence the evolution of their surroundings. In this paper we present a new visualization and use analytical calculations in order to study the influence of these first stars. The visualization was created using both Enzo, a simulation program that uses adaptive mesh refinement, and Amira, a 3D volume rendering program. This visualization allows for a ... continued below

Description

The formation of the first stars marked a crucial transition in the formation of structure in the universe. Through their feedback effects, which include ionization by their radiation and the supernovae or black holes formed at the end of their lives, they were able to influence the evolution of their surroundings. In this paper we present a new visualization and use analytical calculations in order to study the influence of these first stars. The visualization was created using both Enzo, a simulation program that uses adaptive mesh refinement, and Amira, a 3D volume rendering program. This visualization allows for a better understanding of the impact these stars had on their surroundings and conveys the importance of these stars to a broader audience. The analytical calculations used investigate the possibility that black holes left by the first stars could be seeds for the 10{sup 9} M{sub {circle_dot}} black holes seen as quasars at redshift z{approx}6. We find that if a remnant black hole was to begin Eddington accretion at z{approx}20, then it would be able to form a 10{sup 9} M{sub {circle_dot}} black hole by z{approx}6, but that there is likely to be a delay in the onset of accretion onto the seed black hole because of the radiative feedback of its progenitor. Future, more detailed numerical calculations will be necessary to understand whether the black holes left by the first stars could possibly be seeds for quasar formation.
