Hydrodynamical simulations of merging galaxy clusters: giant dark matter particle colliders, powered by gravity
Ellen L. Sirks, David Harvey, Richard Massey +7
Terrestrial particle accelerators collide charged particles, then watch the trajectory of outgoing debris - but they cannot manipulate dark matter. Fortunately, dark matter is the…

Weak gravitational lensing measurements of Abell 2744 using JWST and shear measurement algorithm pyRRG-JWST
David R. Harvey, Richard Massey
We update the publicly available weak lensing shear measurement algorithm pyRRG for the James Webb Space Telescope, and apply it to UNCOVER DR1 imaging of galaxy cluster Abell 2744…
