Foreground simulations for the LOFAR - Epoch of Reionization Experiment
Vibor Jelic, Saleem Zaroubi, Panagiotis Labropoulos +10
Future high redshift 21-cm experiments will suffer from a high degree of contamination, due both to astrophysical foregrounds and to non-astrophysical and instrumental effects. In…
A large population of metal-rich, compact, intergalactic C IV absorbers - Evidence for poor small-scale metal mixing
Joop Schaye, Robert F. Carswell, Tae-Sun Kim
We carried out a survey for high-metallicity C IV absorbers at redshift z ~ 2.3 in the spectra of 9 high-quality quasar spectra. Using a novel analysis technique, based on detectio…
Explaining the Lyman-alpha forest
Joop Schaye
It is shown that many properties of Ly-alpha forest absorbers can be derived using simple physical arguments. Analytical expressions are derived for the density and the size of an…
Mining for Metals in the Lyman Alpha Forest
Sara L. Ellison, Antoinette Songaila, Joop Schaye +1
In order to ascertain the extent of metal enrichment in the Ly alpha forest, we have analysed a very high S/N spectrum of the z = 3.625 QSO Q1422+231. We find that in high column d…
Constraining reionization using the thermal history of the baryons
Joop Schaye, Tom Theuns, Michael Rauch +2
The thermal evolution of the intergalactic medium (IGM) depends on the reionization history of the universe. Numerical simulations indicate that the low density IGM, which is respo…
Measuring the temperature of the intergalactic medium
Joop Schaye, Tom Theuns, Anthony Leonard +1
Numerical simulations indicate that the smooth, photoionized intergalactic medium (IGM) responsible for the low column density Lyman-alpha forest follows a well defined temperature…
