Different traces give different gravitational mass distributions [PDF]

, 2009
Context. Charting the extent and amount of dark matter (DM) in the Universe is highly appealing but is equally hard since it is only through the interpretation of its effect that we can track the DM distribution, i.e.

Non-parametric modeling of the intra-cluster gas using APEX-SZ bolometer imaging data [PDF]

, 2010
Aims. We aim to demonstrate the usability of mm-wavelength imaging data obtained from the APEX-SZ bolometer array to derive the radial temperature profile of the hot intra-cluster gas out to radius r(500) and beyond.
