Cosmic variance of the local Hubble flow in large-scale cosmological simulations
Radoslaw Wojtak, Alexander Knebe, William A. Watson +5
The increasing precision in the determination of the Hubble parameter has reached a per cent level at which large-scale cosmic flows induced by inhomogeneities of the matter distri…
Dark Matter in the Local Universe
Gustavo Yepes, Stefan Gottloeber, Yehuda Hoffman
We review how dark matter is distributed in our local neighbourhood from an observational and theoretical perspective. We will start by describing first the dark matter halo of our…
Simulations of the Local Universe Constrained by Observational Peculiar Velocities
Jenny G. Sorce, Helene M. Courtois, Stefan Gottloeber +2
Peculiar velocities, obtained from direct distance measurements, are data of choice to achieve constrained simulations of the Local Universe reliable down to a scale of a few Megap…
The stellar-to-halo mass relation for Local Group galaxies
C. B. Brook, A. Di Cintio, A. Knebe +4
We contend that a single power law halo mass distribution is appropriate for direct matching to the stellar masses of observed Local Group dwarf galaxies, allowing the determinatio…
Halo Abundance Matching: accuracy and conditions for numerical convergence
Anatoly Klypin, Francisco Prada, Gustavo Yepes +2
Accurate predictions of the abundance and clustering of dark matter haloes play a key role in testing the standard cosmological model. Here, we investigate the accuracy of one of t…
The velocity shear and vorticity across redshifts and non-linear scales
Noam I Libeskind, Yehuda Hoffman, Stefan Gottlöber
The evolution of the large scale distribution of matter in the universe is often characterized by the density field. Here we take a complimentary approach and characterize it using…
High resolution simulations of the reionization of an isolated Milky Way - M31 galaxy pair
P. Ocvirk, D. Aubert, J. Chardin +5
We present the results of a set of numerical simulations aimed at studying reionization at galactic scale. We use a high resolution simulation of the formation of the Milky Way-M31…
The MUSIC of Galaxy Clusters III: Properties, evolution and Y-M scaling relation of protoclusters of galaxies
Federico Sembolini, Marco De Petris, Gustavo Yepes +3
In this work we study the properties of protoclusters of galaxies by employing the MUSIC set of hydrodynamical simulations, featuring a mass-limited sample of 282 resimulated clust…
The Jubilee ISW Project I: simulated ISW and weak lensing maps and initial power spectra results
W. A. Watson, J. M. Diego, S. Gottlöber +11
We present initial results from the Jubilee ISW project, which models the expected \LambdaCDM Integrated Sachs-Wolfe (ISW) effect in the Jubilee simulation. The simulation volume i…
Dynamical signatures of infall around galaxy clusters: a generalized Jeans equation
Martina Falco, Gary A. Mamon, Radoslaw Wojtak +2
We study the internal kinematics of galaxy clusters in the region beyond the sphere of virialization. Galaxies around a virialized cluster are infalling towards the cluster centre…
Cold versus Warm Dark Matter simulations of a galaxy group
Noam I. Libeskind, Arianna Di Cintio, Alexander Knebe +5
The differences between cold (CDM) and warm (WDM) dark matter in the formation of a group of galaxies is examined by running two identical simulations where in the WDM case the ini…
Statistics of extreme objects in the Juropa Hubble Volume simulation
W. A. Watson, I. T. Iliev, J. M. Diego +4
We present the first results from the JUropa huBbLE volumE (Jubilee) project, based a large N-body, dark matter-only cosmological simulation with a volume of $V=(6 h^{-1}\mathrm{Gp…
Simulating Structure Formation of the Local Universe
Steffen Heß, Francisco-Shu Kitaura, Stefan Gottloeber
In this work we present cosmological N-body simulations of the Local Universe with initial conditions constrained by the Two-Micron Redshift Survey (2MRS) within a cubic volume of…
Structure Finding in Cosmological Simulations: The State of Affairs
Alexander Knebe, Frazer R. Pearce, Hanni Lux +32
The ever increasing size and complexity of data coming from simulations of cosmic structure formation demands equally sophisticated tools for their analysis. During the past decade…
The kinematics of the Local Group in a cosmological context
Jaime E. Forero-Romero, Yehuda Hoffman, Sebastian Bustamante +2
Recent observations constrained the tangential velocity of M31 with respect to the Milky Way (MW) to be v_tan<34.4 km/s and the radial velocity to be in the range v_rad=-109+/- 4.4…
Orbital anisotropy in cosmological haloes revisited
Radoslaw Wojtak, Stefan Gottloeber, Anatoly Klypin
The velocity anisotropy of particles inside dark matter (DM) haloes is an important physical quantity, which is required for the accurate modelling of mass profiles of galaxies and…
