XMM Cluster Survey

The XMM Cluster Survey (XCS) is a serendipitous X-ray galaxy cluster survey being conducted using archival data taken by ESA’s XMM-Newton satellite. Galaxy clusters trace the large scale structure of the universe, and their number density evolution with redshift provides a way to measure cosmological parameters, independent of cosmic microwave background experiments or supernovae cosmology projects.[1]

The collaboration is based in the United Kingdom and this is also where the majority of researchers are based. However, there are members of the collaboration across Europe and the Atlantic.

Science Goals
  • Derivation of cosmological parameters
  • Measurement of X-ray scaling relations and their evolution
  • Galaxy evolution in dense environments
  • Properties of unusual (non cluster) X-ray sources, such as high redshift quasars and isolated neutron stars.

Achievements

The XCS collaboration have detected 503 clusters serendipitously in XMM-Newton observations.[2]

gollark: Also, you could sort of gain extra senses of some possible value by mapping things like LIDAR output (AR glasses will probably have something like that for object recognition) and the local wireless environment onto the display.
gollark: Oh, and there's the obvious probably-leading-to-terrible-consequences thing of being able to conveniently see the social media profiles of anyone you meet.
gollark: Some uses: if you are going shopping in a real-world shop you could get reviews displayed on the items you look at; it could be a more convenient interface for navigation apps; you could have an instructional video open while learning to do something (which is already doable on a phone, yes, but then you have to either hold or or stand it up somewhere, which is somewhat less convenient), and with some extra design work it could interactively highlight the things you're using; you could implement a real-world adblocker if there's some way to dim/opacify/draw attention away from certain bits of the display.
gollark: There's nothing you can't *technically* do with a phone, but a more convenient interface does a lot.
gollark: There are rather a lot of cool uses for being able to overlay information on reality.
