Non-voigt Lyα absorption line profiles.

OUTRAM P.J., CARSWELL R.F. and THEUNS T.

Abstract (from CDS):

Recent numerical simulations have lead to a paradigm shift in our understanding of the intergalactic medium and the loss of a physical justification for Voigt profile fitting of the Lyα forest. Many individual lines seen in simulated spectra have significant departures from the Voigt profile, yet could be well fitted by a blend of two or more such lines. We discuss the expected effect on the line profiles due to ongoing gravitational structure formation and Hubble expansion. We develop a method to detect departures from Voigt profiles of the absorption lines in a statistical way and apply this method to simulated Lyα forest spectra, confirming that the profiles seen do statistically differ from Voigt profiles.
