TL;DR: Hiss et al. as mentioned in this paper decompose the Lyman-α (Lyα) forest of an extensive sample of 75 high signal-to-noise ratio and high-resolution quasar spectra into a collection of Voigt profiles.

TL;DR: In this article, a profile fitting procedure for the inverted transmitted flux, $1-F$, similar to the widely used Voigt profile fitting of the transmitted flux $F$ at lower redshifts, was used to characterise the transmission spikes that probe predominately underdense regions of the intergalactic medium (IGM).

TL;DR: In this paper, a new measurement of the Lyα forest power spectrum at 1.8 l z l 3.4 using 74 Keck/HIRES and VLT/UVES high-resolution, high-signal-to-noise-ratio quasar spectra was presented.

TL;DR: In this paper, the temperature-density relationship (TDR) of the intergalactic medium (IGM) in the redshift range 2.55 < z < 2.95 was measured using a sample of 13 high-quality quasar spectra and high resolution numerical simulations of the IGM.

TL;DR: The authors' measurements are consistent with standard models for photoionization heating by the ultraviolet radiation backgrounds that reionized the universe and compared to hydrodynamical simulations, where pressure smoothing is determined by the integrated thermal history of the IGM.
