The Growth of Intracluster Light in XCS-HSC Galaxy Clusters from $0.1 < z < 0.5$

We find that the ICL makes up about $\sim$ 24% of the total cluster stellar mass on average ($\sim$ 41% including the flux contained in the BCG within 50 kpc); this value is well-matched with other observational studies and semi-analytic/numerical simulations, but is significantly smaller than results from recent hydrodynamical simulations (even when measured in an observationally consistent way).

Renewal Strings for Cleaning Astronomical Databases

no code implementations7 Aug 2014 Amos J. Storkey, Nigel C. Hambly, Christopher K. I. Williams, Robert G. Mann

Large astronomical databases obtained from sky surveys such as the SuperCOSMOS Sky Surveys (SSS) invariably suffer from a small number of spurious records coming from artefactual effects of the telescope, satellites and junk objects in orbit around earth and physical defects on the photographic plate or CCD.
