A Concordance Model of the Lyman-alpha Forest at z = 1.95

T. Jena, M. L. Norman, D. Tytler +12

We present 40 fully hydrodynamical numerical simulations of the intergalactic gas that gives rise to the Ly-alpha forest. We make artificial spectra from each and measure three out…

Evolution strategies applied to the problem of line profile decomposition in QSO spectra

R. Quast, R. Baade, D. Reimers

We describe the decomposition of QSO absorption line ensembles applying an evolutionary forward modelling technique. The modelling is optimized using an evolution strategy (ES) bas…
