The survival of globular clusters in a cuspy Fornax
Shi Shao, Marius Cautun, Carlos S. Frenk +5
It has long been argued that the radial distribution of globular clusters (GCs) in the Fornax dwarf galaxy requires its dark matter halo to have a core of size kpc. We rev…
Deviations from tidal torque theory: evolution of the halo spin-filament alignment
Pablo López, Marius Cautun, Dante Paz +2
The alignment between halo spins and the cosmic web is still poorly understood despite being a widely studied topic. Here, we study this alignment within the context of tidal torqu…
Constraints on the properties of warm dark matter using the satellite galaxies of the Milky Way
Oliver Newton, Matteo Leo, Marius Cautun +5
The satellite galaxies of the Milky Way (MW) are effective probes of the underlying dark matter (DM) substructure, which is sensitive to the nature of the DM particle. In particula…
Caught in the cosmic web: Environmental effect on halo concentrations, shape, and spin
Wojciech A. Hellwing, Marius Cautun, Rien van de Weygaert +1
Using a set of high-resolution simulations we study the statistical correlation of dark matter halo properties with the large-scale environment. We consider halo populations split…
Testing the theory of gravity with DESI: estimators, predictions and simulation requirements
Shadab Alam, Christian Arnold, Alejandro Aviles +33
Shortly after its discovery, General Relativity (GR) was applied to predict the behavior of our Universe on the largest scales, and later became the foundation of modern cosmology.…
Joint constraints on thermal relic dark matter from strong gravitational lensing, the Lyman- forest, and Milky Way satellites
Wolfgang Enzi, Riccardo Murgia, Oliver Newton +10
We derive joint constraints on the warm dark matter (WDM) half-mode scale by combining the analyses of a selection of astrophysical probes: strong gravitational lensing with extend…
Constraining cosmology with weak lensing voids
Christopher T. Davies, Marius Cautun, Benjamin Giblin +3
Upcoming surveys such as \LSST{} and \Euclid{} will significantly improve the power of weak lensing as a cosmological probe. To maximise the information that can be extracted from…
Cosmic Ballet III: halo spin evolution in the cosmic web
Punyakoti Ganeshaiah Veena, Marius Cautun, Rien van de Weygaert +2
We explore the evolution of halo spins in the cosmic web using a very large sample of dark matter haloes in the CDM Planck-Millennium N-body simulation. We use the NEXUS+ multis…
The twisted dark matter halo of the Milky Way
Shi Shao, Marius Cautun, Alis J. Deason +1
We analyse systems analogous to the Milky Way (MW) in the EAGLE cosmological hydrodynamics simulation in order to deduce the likely structure of the MW's dark matter halo. We ident…
Optimal void finders in weak lensing maps
Christopher T. Davies, Enrique Paillas, Marius Cautun +1
Cosmic voids are a key component of the large-scale structure that contain a plethora of cosmological information. Typically, voids are identified from the underlying galaxy distri…
The orbital phase space of contracted dark matter halos
Thomas M. Callingham, Marius Cautun, Alis J. Deason +4
We study the orbital phase-space of dark matter (DM) halos in the AURIGA suite of cosmological hydrodynamics simulations of Milky Way analogues. We characterise halos by their sphe…
