Characterizing the Low-redshift Intergalactic Medium towards Pks1302–102
We present a detailed analysis of the intergalactic metal-line absorption systems in the archival HST/STIS and FUSE ultraviolet spectra of the low-redshift quasar PKS1302–102 (zQSO = 0.2784). We supplement the archive data with CLOUDY ionization models and a survey of galaxies in the quasar field. There are 15 strong Lyα absorbers with column densities logNHI > 14. Of these, six are associated ...
متن کاملAbundances in the high - redshift Intergalactic Medium
The enrichment of the intergalactic medium (IGM) with heavy elements provides us with a record of past star formation and with an opportunity to study the interactions between galaxies and their environments. We summarize current data analysis methods and observational constraints on abundances in the diffuse, high-redshift (z > 2) IGM. This review is targeted at interested outsiders and attemp...
متن کاملFluorescent Lyα Emission from the High-redshift Intergalactic Medium
We combine a high-resolution hydro-simulation of the ΛCDM cosmology with two radiative transfer schemes (for continuum and line radiation) to predict the properties, spectra and spatial distribution of fluorescent Lyα emission at z ∼ 3. We focus on line radiation produced by recombinations in the dense intergalactic medium ionized by UV photons. In particular, we consider both a uniform backgro...
متن کاملX-ray Absorption by the Low-redshift Intergalactic Medium: A Numerical Study of the ΛCDM model
Using a hydrodynamic simulation of a cold dark matter universe with a cosmological constant (ΛCDM), we investigate the “X-ray forest” absorption imprinted on the spectra of background quasars by the intervening intergalactic medium (IGM), at redshift z ≈ 0. In agreement with previous studies, we find that O VII and O VIII produce the strongest absorption features. The strong oxygen absorbers th...
متن کاملTracing the Warm-Hot Intergalactic Medium at Low Redshift: X-ray Forest Observations Towards H1821+643
We present a high resolution (λ/∆λ ≈ 500) X-ray spectrum of the bright quasar H1821+643 (z = 0.297), obtained in a 470 ksec observation with the Chandra X-ray Observatory. We search for X-ray absorption by highly ionized metal species, Ovii and Oviii in particular, at the redshifts of the six intervening Ovi absorption systems known from UV studies. We detect features with & 2σ significance at ...
