Angular Momentum Evolution in Dark Matter Halos
Laura G. Book, Alyson Brooks, Annika H. G. Peter +2
We have analyzed high resolution N-body simulations of dark matter halos, focusing specifically on the evolution of angular momentum. We find that not only is individual particle a…
The Dual Origin of Stellar Halos II: Chemical Abundances as Tracers of Formation History
Adi Zolotov, Beth Willman, Alyson Brooks +4
Fully cosmological, high resolution N-Body + SPH simulations are used to investigate the chemical abundance trends of stars in simulated stellar halos as a function of their origin…
Analytic and numerical realisations of a disk galaxy
M. J. Stringer, A. M. Brooks, A. J. Benson +1
Recent focus on the importance of cold, unshocked gas accretion in galaxy formation -- not explicitly included in semi-analytic studies -- motivates the following detailed comparis…
