A recent comparison of the massive galaxy cluster Abell 2744 with the Millennium XXL (MXXL) N-body simulation has hinted at a tension between the observed substructure distribution and the predictions of Λ cold dark matter (ΛCDM). Follow-up investiga... Read More about Uncovering substructure with wavelets: proof of concept using Abell 2744.

We present a gravitational lensing and X-ray analysis of a massive galaxy cluster and its surroundings. The core of MACS J0717.5+3745 (M(R < 1 Mpc) ∼ 2 × 1015 M, z = 0.54) is already known to contain four merging components. We show that this is surr...

Gilmozzi (Eds.), Ground-based and Airborne Telescopes VII : 10–15 June 2018, Austin, Texas, United States ; proceedings. https://doi.org/10.1117/12.2312339

Balloon-borne experiments present unique thermal design challenges, which are a combination of those present for both space and ground experiments. Radiation and conduction are the predominant heat transfer mechanisms with convection effects being mi... Read More about Auto-tuned thermal control on stratospheric balloon experiments.

A galaxy cluster acts as a cosmic telescope over background galaxies but also as a cosmic microscope magnifying the imperfections of the lens. The diverging magnification of lensing caustics enhances the microlensing effect of substructure present wi...
