  • Accurate photometric redshift probability density estimation - method comparison and application

    Rau, Michael M.; Seitz, Stella; Frank, Eibe; Brimioulee, Fabrice; Friedrich, Oliver; Gruen, Daniel; Hoyle, Ben (Oxford University Press (OUP): Policy P - Oxford Open Option A, 2015)
    We introduce an ordinal classification algorithm for photometric redshift estimation, which significantly improves the reconstruction of photometric redshift probability density functions (PDFs) for individual galaxies and ...

  • Fast magnetic reconnection via jets and current microsheets

    Watson, P.G.; Craig, Ian J.D. (The American Astronomical Society, 2003-06)
    Numerical simulations of highly nonlinear magnetic reconnection provide evidence of ultrathin current microsheets. These small-scale sheets are formed by strong exhaust jets from a primary large-scale current layer. The ...
