Detecting HeliumII reionization from a sudden injection of entropy in the intergalactic medium
Tom Theuns, Saleem Zaroubi, Tae-Sun Kim
The temperature of the low-density intergalactic medium is set by the balance between adiabatic cooling resulting from the expansion of the universe, and photo-heating by the UV-ba…
Temperature fluctuations in the intergalactic medium
Tom Theuns, Saleem Zaroubi, Tae-Sun Kim +2
The temperature of the low-density intergalactic medium is set by the balance between adiabatic cooling resulting from the expansion of the universe, and photo-heating by the UV-ba…
PINOCCHIO and the hierarchical build-up of dark matter haloes
G. Taffoni, P. Monaco, T. Theuns
We study the ability of PINOCCHIO (PINpointing Orbit-Crossing Collapsed HIerarchical Objects) to predict the merging histories of dark matter (DM) haloes, comparing the PINOCCHIO p…
Predicting the number, spatial distribution and merging history of dark matter haloes
P. Monaco, T. Theuns, G. Taffoni +3
We present a new algorithm (PINOCCHIO, PINpointing Orbit-Crossing Collapsed HIerarchical objects) to predict accurately the formation and evolution of individual dark matter haloes…
PINOCCHIO: pinpointing orbit-crossing collapsed hierarchical objects in a linear density field
P. Monaco, T. Theuns, G. Taffoni
PINOCCHIO (PINpointing Orbit-Crossing Collapsed Hierarchical Objects) is a new algorithm for identifying dark matter halos in a given numerical realisation of the linear density fi…
