Reconstructing cosmological initial conditions from galaxy peculiar velocities. III. Constrained simulations
Timur Doumler, Stefan Gottloeber, Yehuda Hoffman +1
In previous works we proposed the Reverse Zeldovich Approximation (RZA) method, which can be used to estimate the cosmological initial conditions underlying the galaxy distribution…
Reconstructing cosmological initial conditions from galaxy peculiar velocities. II. The effect of observational errors
Timur Doumler, Helene Courtois, Stefan Gottloeber +1
The Reverse Zeldovich Approximation (RZA) is a reconstruction method which allows to estimate the cosmic displacement field from galaxy peculiar velocity data and to constrain init…
Reconstructing cosmological initial conditions from galaxy peculiar velocities. I. Reverse Zeldovich Approximation
Timur Doumler, Yehuda Hoffman, Helene Courtois +1
We propose a new method to recover the cosmological initial conditions of the presently observed galaxy distribution, which can serve to run constrained simulations of the Local Un…
Cosmic vorticity and the origin of halo spins
Noam I Libeskind, Yehuda Hoffman, Matthias Steinmetz +3
In the standard model of cosmology, structure emerges out of non-rotational flow and the angular momentum of collapsing halos is induced by tidal torques. The growth of halo angula…
Dwarf Galaxies and the Cosmic Web
Alejandro Benitez-Llambay, Julio F. Navarro, Mario G. Abadi +4
We use a cosmological simulation of the formation of the Local Group of Galaxies to identify a mechanism that enables the removal of baryons from low-mass halos without appealing t…
The velocity shear tensor: tracer of halo alignment
Noam I. Libeskind, Yehuda Hoffman, Jaime Forero-Romero +4
The alignment of DM halos and the surrounding large scale structure (LSS) is examined in the context of the cosmic web. Halo spin, shape and the orbital angular momentum of subhalo…
