Broadening of QSO Lyα forest absorbers
We investigate the dependence of QSO Lyα absorption features on the temperature of the absorbing gas and on the amplitude of the underlying dark matter fluctuations. We use high-resolution hydrodynamic simulations in cold dark matter dominated cosmological models. In models with a hotter intergalactic medium (IGM), the increased temperature enhances the pressure gradients between low and high d...
متن کاملThe Local Lyα Forest: Association of Absorbers with Galaxies, Voids and Superclusters
We describe recent discoveries of low column density (NHI ≤ 10 cm) H I Lyα absorbers made with the Hubble Space Telescope (HST) which have allowed us a first look at gas in local intergalactic space between us and the “Great Wall”. Despite the mere 2.4m aperture of HST, these new observations allow us to detect absorbers with column densities, NHI ≈ 10 12.5 cm, as low as those found using Keck/...
متن کاملEXTREME ULTRAVIOLET ABSORPTION LINES IN Lyα FOREST ABSORBERS AND THE OXYGEN ABUNDANCE IN THE INTERGALACTIC MEDIUM
We create stacked composite absorption spectra from Hubble Space Telescope Faint Object Spectrograph data from four quasi-stellar objects to search for absorption lines in the extreme ultraviolet wavelength region associated with Lyα forest absorbers in the redshift range 1.6 < z < 2.9. We successfully detect O V λ630 in Lyα absorbers throughout the 1013 to 1016.2 cm−2 column density range. For...
متن کاملLyα ABSORBER CORRELATIONS AND THE “BIAS” OF THE Lyα FOREST
Lyα absorber correlations contain information about the underlying density distribution associated with a particular class of absorbers. As such, they provide an opportunity to independently measure the “bias” of the Lyman alpha forest, i.e. the relationship between H I column density and underlying dark matter density. In these proceedings we use hydrodynamic simulations to investigate whether...
متن کاملDetecting damped Lyα absorbers with Gaussian processes
We develop an automated technique for detecting damped Lyα absorbers (DLAs) along spectroscopic lines of sight to quasi-stellar objects (QSOs or quasars). The detection of DLAs in large-scale spectroscopic surveys such as SDSS III sheds light on galaxy formation at high redshift, showing the nucleation of galaxies from diffuse gas. We use nearly 50 000 QSO spectra to learn a novel tailored Gaus...
