Dark matter dynamics in Abell 3827: new data consistent with standard Cold Dark Matter
Richard Massey, David Harvey, Jori Liesenborgs +23
We present integral field spectroscopy of galaxy cluster Abell 3827, using ALMA and VLT/MUSE. It reveals an unusual configuration of strong gravitational lensing in the cluster cor…
The behaviour of dark matter associated with 4 bright cluster galaxies in the 10kpc core of Abell 3827
Richard Massey, Liliya Williams, Renske Smit +20
Galaxy cluster Abell 3827 hosts the stellar remnants of four almost equally bright elliptical galaxies within a core of radius 10kpc. Such corrugation of the stellar distribution i…
The non-gravitational interactions of dark matter in colliding galaxy clusters
David Harvey, Richard Massey, Thomas Kitching +2
Collisions between galaxy clusters provide a test of the non-gravitational forces acting on dark matter. Dark matter's lack of deceleration in the `bullet cluster collision' constr…
Gas around galaxy haloes: methodology comparisons using hydrodynamical simulations of the intergalactic medium
Avery Meiksin, James S. Bolton, Eric R. Tittley
We perform cosmological simulations of the intergalactic medium (IGM) at redshift z ~ 3 using the numerical gravity-hydrodynamics codes GADGET-3 and Enzo for the purpose of modelli…
On the cross-section of Dark Matter using substructure infall into galaxy clusters
David Harvey, Eric Tittley, Richard Massey +6
We develop a statistical method to measure the interaction cross-section of Dark Matter, exploiting the continuous minor merger events in which small substructures fall into galaxy…
Dark Matter Astrometry: Accuracy of sub-halo positions for the measurement of self-interaction cross sections
David Harvey, Richard Massey, Thomas Kitching +5
Direct evidence for the existence of dark matter and measurements of its interaction cross-section have been provided by the physical offset between dark matter and intra- cluster…
