The Santiago-Harvard-Edinburgh-Durham void comparison II: unveiling the Vainshtein screening using weak lensing
Enrique Paillas, Marius Cautun, Baojiu Li +4
We study cosmic voids in the normal-branch Dvali-Gabadadze-Porrati (nDGP) braneworld models, which are representative of a class of modified gravity theories where deviations from…
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…
Reconstructing the baryon acoustic oscillations using biased tracers
Jack Birkin, Baojiu Li, Marius Cautun +1
The reconstruction of the initial conditions of the Universe is an important topic in cosmology, particularly in the context of sharpening the measurement of the baryon acoustic os…
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…
The Cosmic Ballet: spin and shape alignments of haloes in the cosmic web
Punyakoti Ganeshaiah Veena, Marius Cautun, Rien van de Weygaert +4
We investigate the alignment of haloes with the filaments of the cosmic web using an unprecedently large sample of dark matter haloes taken from the P-Millennium CDM cosmologica…
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…
Weak lensing by voids in weak lensing maps
Christopher T. Davies, Marius Cautun, Baojiu Li
Cosmic voids are an important probe of large-scale structure that can constrain cosmological parameters and test cosmological models. We present a new paradigm for void studies: vo…
Evolution of LMC/M33-mass dwarf galaxies in the EAGLE simulation
Shi Shao, Marius Cautun, Alis J. Deason +2
We investigate the population of dwarf galaxies with stellar masses similar to the Large Magellanic Cloud (LMC) and M33 in the EAGLE galaxy formation simulation. In the field, gala…
