    • Constraining the growth rate by combining multiple future surveys 

      Viljoen, Jan-Albert; Fonseca, Jos´e; Maartens, Roy (IOP Publishing, 2020)
      The growth rate of large-scale structure provides a powerful consistency test of the standard cosmological model and a probe of possible deviations from general relativity. We use a Fisher analysis to forecast constraints ...

    • Extending BEAMS to incorporate correlated systematic uncertainties 

      Knights, Michelle; Bassett, Bruce A.; Varughese, Melvin; Hlozek, Renee; Kunz, Martin; Smith, Mat; Newling, James (IOP Science, 2013)
      New supernova surveys such as the Dark Energy Survey, Pan-STARRS and the LSST will produce an unprecedented number of photometric supernova candidates, most with no spectroscopic data. Avoiding biases in cosmological ...
