Dark Matter Halos: Velocity Anisotropy -- Density Slope Relation
Amir Zait, Yehuda Hoffman, Isaac Shlosman
Dark matter (DM) halos formed in CDM cosmologies seem to be characterized by a power law phase-space density profile. The density of the DM halos is often fitted by the NFW profile…
The Local Hubble Flow: Is it a Manifestation of Dark Energy?
Yehuda Hoffman, Luis A. Martinez-Vaquero, Gustavo Yepes +1
To study the local Hubble flow, we have run constrained dark matter (DM) simulations of the Local Group (LG) in the concordance LCDM and OCDM cosmologies, with identical cosmologic…
Evolution of Phase-Space Density in Dark Matter Halos
Yehuda Hoffman, Emilio Romano-Diaz, Isaac Shlosman +1
The evolution of the phase-space density profile in dark matter (DM) halos is investigated by means of constrained simulations, designed to control the merging history of a given D…
The Future of the Local Large Scale Structure: the roles of Dark Matter and Dark Energy
Yehuda Hoffman, Ofer Lahav, Gustavo Yepes +1
We study the distinct effects of Dark Matter and Dark Energy on the future evolution of nearby large scale structures using constrained N-body simulations. We contrast a model of C…
Constrained simulations of the local universe: I. Mass and motion in the Local Volume
Luis A. Martinez-Vaquero, Gustavo Yepes, Yehuda Hoffman
It has been recently claimed that there is no correlation between the distribution of galaxies and their peculiar velocities within the Local Volume (LV), namely a sphere of R=7/h…
