The halo mass function from the dark ages through the present day

The halo mass function from the dark ages through the present day

We use an array of high-resolution N-body simulations to determine the mass function of dark matter haloes at redshifts 10–30. We develop a new method for compensating for the effects of finite simulation volume that allows us to find an approximation to the true ‘global’ mass function. By simulating a …
