New Statistical Measures of the Lya Forest Spectra for Accurate Comparison to Theoretical Models
J. Miralda-Escude, M. Rauch, W. L. W. Sargent +6
We propose a new method of analysis for the \lya forest, namely to measure the 1-point and 2-point joint probability distribution of the transmitted flux. The results for a sample…
Time stepping N-body simulations
Thomas Quinn, Neal Katz, Joachim Stadel +1
Leapfrog integration has been the method of choice in N-body simulations owing to its low computational cost for a symplectic integrator with second order accuracy. We introduce a…
Hubble Flow Broadening of the Lyman-alpha Forest and its Implications
David H. Weinberg, Lars Hernquist, Neal Katz +2
Lyman-alpha forest lines in QSO spectra have typical widths of 20-50 km/s. Low column density absorbers in cosmological simulations are large, diffuse structures, and the Hubble fl…
Characterization of Lyman Alpha Spectra and Predictions of Structure Formation Models: A Flux Statistics Approach
Rupert A. C. Croft, David H. Weinberg, Lars Hernquist +1
In gravitational instability models, \lya absorption arises from a continuous fluctuating medium, so that spectra provide a non-linear one-dimensional ``map'' of the underlying den…
