A new Measurement of the Intergalactic Temperature at
Alberto Rorai, Robert F. Carswell, Martin G. Haehnelt +3
We present two measurements of the temperature-density relationship (TDR) of the intergalactic medium (IGM) in the redshift range using a sample of 13 high-qualit…
The effect of stellar and AGN feedback on the low redshift Lyman- forest in the Sherwood simulation suite
Fahad Nasir, James S. Bolton, Matteo Viel +4
We study the effect of different feedback prescriptions on the properties of the low redshift () Ly forest using a selection of hydrodynamical simulations drawn from t…
First constraints on fuzzy dark matter from Lyman- forest data and hydrodynamical simulations
Vid Iršič, Matteo Viel, Martin G. Haehnelt +2
We present constraints on the masses of extremely light bosons dubbed fuzzy dark matter from Lyman- forest data. Extremely light bosons with a De Broglie wavelength of …
The Lyman-alpha forest power spectrum from the XQ-100 Legacy Survey
Vid Iršič, Matteo Viel, Trystyn A. M. Berg +12
We present the Lyman- flux power spectrum measurements of the XQ-100 sample of quasar spectra obtained in the context of the European Southern Observatory Large Programme "Quasa…
New Constraints on the free-streaming of warm dark matter from intermediate and small scale Lyman- forest data
Vid Iršič, Matteo Viel, Martin G. Haehnelt +12
We present new measurements of the free-streaming of warm dark matter (WDM) from Lyman- flux-power spectra. We use data from the medium resolution, intermediate redshift XQ-100…
Gas around galaxy haloes - III: hydrogen absorption signatures around galaxies and QSOs in the Sherwood simulation suite
Avery Meiksin, James S. Bolton, Ewald Puchwein
Modern theories of galaxy formation predict that galaxies impact on their gaseous surroundings, playing the fundamental role of regulating the amount of gas converted into stars. W…
