Reconciling galaxy cluster shapes, measured by theorists vs observers
David Harvey, Andrew Robertson, Sut-Ieng Tam +4
If properly calibrated, the shapes of galaxy clusters can be used to investigate many physical processes: from feedback and quenching of star formation, to the nature of dark matte…
A forward-modelling method to infer the dark matter particle mass from strong gravitational lenses
Qiuhan He, Andrew Robertson, James Nightingale +7
A fundamental prediction of the cold dark matter (CDM) model of structure formation is the existence of a vast population of dark matter haloes extending to subsolar masses. By con…
The surprising accuracy of isothermal Jeans modelling of self-interacting dark matter density profiles
Andrew Robertson, Richard Massey, Vincent Eke +2
Recent claims of observational evidence for self-interacting dark matter (SIDM) have relied on a semi-analytic method for predicting the density profiles of galaxies and galaxy clu…
The distribution of dark matter and gas spanning six megaparsecs around the post-merger galaxy cluster MS0451-03
Sut-Ieng Tam, Mathilde Jauzac, Richard Massey +11
Using the largest mosaic of Hubble Space Telescope images around a galaxy cluster, we map the distribution of dark matter throughout a Mpc area centred on the…
Mapping dark matter and finding filaments: calibration of lensing analysis techniques on simulated data
Sut-Ieng Tam, Richard Massey, Mathilde Jauzac +1
We quantify the performance of mass mapping techniques on mock imaging and gravitational lensing data of galaxy clusters. The optimum method depends upon the scientific goal. We as…
Velocity-dependent Self-interacting Dark Matter from Groups and Clusters of Galaxies
Laura Sagunski, Sophia Gad-Nasr, Brian Colquhoun +2
We probe the self-interactions of dark matter using observational data of relaxed galaxy groups and clusters. Our analysis uses the Jeans formalism and considers a wider range of s…
