Looking for dark matter trails in colliding galaxy clusters (2016)
Journal Article
Harvey, D., Robertson, A., Massey, R., & Kneib, J. (2017). Looking for dark matter trails in colliding galaxy clusters. Monthly Notices of the Royal Astronomical Society, 464(4), 3991-3997. https://doi.org/10.1093/mnras/stw2671

If dark matter interacts, even weakly, via non-gravitational forces, simulations predict that it will be preferentially scattered towards the trailing edge of the halo during collisions between galaxy clusters. This will temporarily create a non-symm... Read More about Looking for dark matter trails in colliding galaxy clusters.

What does the Bullet Cluster tell us about self-interacting dark matter? (2016)
Journal Article
Robertson, A., Massey, R., & Eke, V. (2017). What does the Bullet Cluster tell us about self-interacting dark matter?. Monthly Notices of the Royal Astronomical Society, 465(1), 569-587. https://doi.org/10.1093/mnras/stw2670

We perform numerical simulations of the merging galaxy cluster 1E 0657−56 (the Bullet Cluster), including the effects of elastic dark matter scattering. In a similar manner to the stripping of gas by ram pressure, dark matter self-interactions would... Read More about What does the Bullet Cluster tell us about self-interacting dark matter?.

The Extraordinary Amount of Substructure in the Hubble Frontier Fields Cluster Abell 2744 (2016)
Journal Article
Jauzac, M., Eckert, D., Schwinn, J., Harvey, D., Baugh, C., Robertson, A., …Tchernin, C. (2016). The Extraordinary Amount of Substructure in the Hubble Frontier Fields Cluster Abell 2744. Monthly Notices of the Royal Astronomical Society, 463(4), 3876-3893. https://doi.org/10.1093/mnras/stw2251

We present a joint optical/X-ray analysis of the massive galaxy cluster Abell 2744 (z=0.308). Our strong- and weak-lensing analysis within the central region of the cluster, i.e., at R < 1 Mpc from the brightest cluster galaxy, reveals eight substruc...

Euclid-VIS is the large format visible imager for the ESA Euclid space mission in their Cosmic Vision program, scheduled for launch in 2020. Together with the near infrared imaging within the NISP instrument, it forms the basis of the weak lensing me... Read More about VIS: the visible imager for Euclid.

We present a weak lensing study of the galaxy cluster IDCS J1426.5+3508 at z = 1.75, which is the highest-redshift strong lensing cluster known and the most distant cluster for which a weak lensing analysis has been undertaken. Using F160W, F814W, an... Read More about IDCS J1426.5+3508: Weak Lensing Analysis of a Massive Galaxy Cluster at z = 1.75.

We present a weak-lensing analysis of the merging Frontier Fields (FF) cluster Abell 2744 using new Subaru/Suprime-Cam imaging. The wide-field lensing mass distribution reveals this cluster is comprised of four distinct substructures. Simultaneously...
