A younger Universe implied by satellite pair correlations from SDSS observations of massive galaxy groups
Qing Gu, Qi Guo, Marius Cautun +5
Many of the satellites of galactic-mass systems such as the Miky Way, Andromeda and Centaurus A show evidence of coherent motions to a larger extent than most of the systems predic…
The impact of the Large Magellanic Cloud on dark matter direct detection signals
Adam Smith-Orlik, Nima Ronaghi, Nassim Bozorgnia +9
We study the effect of the Large Magellanic Cloud (LMC) on the dark matter (DM) distribution in the Solar neighborhood, utilizing the Auriga magneto-hydrodynamical simulations of M…
Determining Satellite Infall Times Using Machine Learning
Stan Barmentloo, Marius Cautun
A key unknown of the Milky Way (MW) satellites is their orbital history, and, in particular, the time they were accreted onto the MW system since it marks the point where they expe…
The spatial distribution of satellites in galaxy clusters
Qing Gu, Qi Guo, Tianchi Zhang +4
The planar distributions of satellite galaxies around the Milky Way and Andromeda have been extensively studied as potential challenges to the standard cosmological model. Using th…
The Milky Way's plane of satellites: consistent with CDM
Till Sawala, Marius Cautun, Carlos S. Frenk +7
The "plane of satellites problem" describes the arrangement of the Milky Way's 11 brightest satellite galaxies in a remarkably thin plane, possibly supported by rotation. This is i…
The Chemo-Dynamical Groups of Galactic Globular Clusters
Thomas M. Callingham, Marius Cautun, Alis J. Deason +3
We introduce a multi-component chemo-dynamical method for splitting the Galactic population of Globular Clusters (GCs) into three distinct constituents: bulge, disc, and stellar ha…
The spatial distribution of Milky Way satellites, gaps in streams and the nature of dark matter
Mark R. Lovell, Marius Cautun, Carlos S. Frenk +2
The spatial distribution of Milky Way (MW) subhaloes provides an important set of observables for testing cosmological models. These include the radial distribution of luminous sat…
Statistical strong lensing. I. Constraints on the inner structure of galaxies from samples of a thousand lenses
Alessandro Sonnenfeld, Marius Cautun
Context: The number of known strong gravitational lenses is expected to grow substantially in the next few years. The statistical combination of large samples of lenses has the pot…
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…
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…
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…
The mass of our Milky Way
Wenting Wang, Jiaxin Han, Marius Cautun +2
We perform an extensive review of the numerous studies and methods used to determine the total mass of the Milky Way. We group the various methods into seven broad classes, includi…
The Milky Way total mass profile as inferred from Gaia DR2
Marius Cautun, Alejandro Benitez-Llambay, Alis J. Deason +7
We determine the Milky Way (MW) mass profile inferred from fitting physically motivated models to the Gaia DR2 Galactic rotation curve and other data. Using various hydrodynamical…
Evolution of galactic planes of satellites in the EAGLE simulation
Shi Shao, Marius Cautun, Carlos S. Frenk
We study the formation of planes of dwarf galaxies around Milky Way (MW)-mass haloes in the EAGLE galaxy formation simulation. We focus on satellite systems similar to the one in t…
The Milky Way's total satellite population and constraining the mass of the warm dark matter particle
Oliver Newton, Marius Cautun, Adrian Jenkins +2
The Milky Way's (MW) satellite population is a powerful probe of warm dark matter (WDM) models as the abundance of small substructures is very sensitive to the properties of the WD…
The aftermath of the Great Collision between our Galaxy and the Large Magellanic Cloud
Marius Cautun, Alis J. Deason, Carlos S. Frenk +1
The Milky Way (MW) offers a uniquely detailed view of galactic structure and is often regarded as a prototypical spiral galaxy. But recent observations indicate that the MW is atyp…
The mass of the Milky Way from satellite dynamics
Thomas Callingham, Marius Cautun, Alis J. Deason +6
We present and apply a method to infer the mass of the Milky Way (MW) by comparing the dynamics of MW satellites to those of model satellites in the EAGLE cosmological hydrodynamic…
Aurigaia: mock Gaia DR2 stellar catalogues from the Auriga cosmological simulations
Robert J. J. Grand, John Helly, Azadeh Fattahi +12
We present and analyse mock stellar catalogues that match the selection criteria and observables (including uncertainties) of the Gaia satellite data release 2 (DR2). The source ar…

Alignments between galaxies, satellite systems and haloes
Shi Shao, Marius Cautun, Carlos S. Frenk +5
The spatial distribution of the satellite populations of the Milky Way and Andromeda are puzzling in that they are nearly perpendicular to the disks of their central galaxies. To u…
