A Merger Tree with Microsolar Mass Resolution: Application to -ray Emission from Subhalo Population
Carlo Giocoli, Lidia Pieri, Giuseppe Tormen +1
The hierarchical growth of dark matter haloes, in which galaxies are hosted, has been studied and modeled using various approaches. In this paper we use a modified version the Shet…
The Population of Dark Matter Subhaloes: Mass Functions and Average Mass Loss Rates
Carlo Giocoli, Giuseppe Tormen, Frank C. van den Bosch
Using a cosmological N-Body simulation and a sample of re-simulated cluster-like haloes, we study the mass loss rates of dark matter subhaloes, and interpret the mass function of s…
Analytical Approach to Subhaloes Population in Dark Matter Haloes
Carlo Giocoli, Lidia Pieri, Giuseppe Tormen
In the standard model of cosmic structure formation, dark matter haloes form by gravitational instability. The process is hierarchical: smaller systems collapse earlier, and later…
Dark matter halo creation in moving barrier models
Jorge Moreno, Carlo Giocoli, Ravi K. Sheth
In hierarchical models, the time derivative of the halo mass function may be thought of as the difference of two terms - a creation term, which describes the increase in the number…
Merger history trees of dark matter haloes in moving barrier models
Jorge Moreno, Carlo Giocoli, Ravi K. Sheth
We present an algorithm for generating merger histories of dark matter haloes. The algorithm is based on the excursion set approach with moving barriers whose shape is motivated by…
An improved model for the formation times of dark matter haloes
Carlo Giocoli, Jorge Moreno, Ravi K. Sheth +1
A dark matter halo is said to have formed when at least half its mass hass been assembled into a single progenitor. With this definition, it is possible to derive a simple but usef…
