Estimation of the masses in the Local Group by Gradient Boosted Decision Trees
Edoardo Carlesi, Yehuda Hoffman, Noam Libeskind
Our goal is to estimate the mass of the Local Group (LG) and the individual masses of its primary galaxies, the M31 and the Milky Way (MW). We do this by means of a supervised mach…
Partitioning the universe into gravitational basins using the cosmic velocity field
A. Dupuy, H. M. Courtois, F. Dupont +8
This letter presents a new approach using the cosmic peculiar velocity field to characterize the morphology and size of large scale structures in the local Universe. The algorithm…
The quasi-linear nearby Universe
Yehuda Hoffman, Edoardo Carlesi, Daniel Pomarède +5
The local Universe provides a unique opportunity for testing cosmology and theories of structure formation. To facilitate this opportunity we present a new method for the reconstru…
The dynamics of the local group as a probe of Dark Energy and Modified Gravity
Edoardo Carlesi, David F. Mota, Hans Winther
In this work we study the dynamics of the Local Group (LG) within the context of cosmological models beyond General Relativity (GR). Using observable kinematic quantities to identi…
Constrained Local UniversE Simulations: A Local Group Factory
Edoardo Carlesi, Jenny G. Sorce, Yehuda Hoffman +8
Near field cosmology is practiced by studying the Local Group (LG) and its neighbourhood. The present paper describes a framework for simulating the near field on the computer. Ass…
Cosmicflows Constrained Local UniversE Simulations
Jenny G. Sorce, Stefan Gottloeber, Gustavo Yepes +6
This paper combines observational datasets and cosmological simulations to generate realistic numerical replicas of the nearby Universe. These latter are excellent laboratories for…
Hidden from view: Coupled Dark Sector Physics and Small Scales
Pascal J. Elahi, Geraint F. Lewis, Chris Power +2
We study cluster mass dark matter haloes, their progenitors and surroundings in an coupled Dark Matter-Dark Energy model and compare it to quintessence and CDM models with adiab…
On the observability of coupled dark energy with cosmic voids
P. M. Sutter, Edoardo Carlesi, Benjamin D. Wandelt +1
Taking N-body simulations with volumes and particle densities tuned to match the SDSS DR7 spectroscopic main sample, we assess the ability of current void catalogs (e.g., Sutter et…
Hydrodynamical simulations of coupled and uncoupled quintessence models II: Galaxy clusters
Edoardo Carlesi, Alexander Knebe, Geraint F. Lewis +1
We study the properties of clusters (and large groups) of galaxies within the context of interacting and non-interacting quintessence cosmological models, using a series of a…
Hydrodynamical simulations of coupled and uncoupled quintessence models I: Halo properties and the cosmic web
Edoardo Carlesi, Alexander Knebe, Geraint F. Lewis +2
We present the results of a series of adiabatic hydrodynamical simulations of several quintessence models (both with a free and an interacting scalar field) in comparison to a stan…
N-body simulations with a cosmic vector for dark energy
Edoardo Carlesi, Alexander Knebe, Gustavo Yepes +3
We present the results of a series of cosmological -body simulations of a Vector Dark Energy (VDE) model, performed using a suitably modified version of the publicly available \…
Vector dark energy and high-z massive clusters
Edoardo Carlesi, Alexander Knebe, Gustavo Yepes +3
The detection of extremely massive clusters at such as SPT-CL J0546-5345, SPT-CL J2106-5844, and XMMU J2235.3-2557 has been considered by some authors as a challenge to the s…
