The evolution of the low-density HI intergalactic medium from z=3.6 to 0: Data, transmitted flux and HI column density
Tae-Sun Kim, Bart P. Wakker, Fahad Nasir +8
We present a new, uniform analysis of the HI transmitted flux (F) and HI column density (N(HI)) distribution in the low-density IGM as a function of redshift z for 0<z<3.6 using 55…
Probing Inhomogeneity in the Helium Ionizing UV Background
Sean Morrison, Matthew M. Pieri, David Syphers +1
We present an analysis combining the simultaneous measurement of intergalactic absorption by hydrogen (H I), helium (He II) and oxygen (O VI) in UV and optical quasar spectra. The…
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…
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…
Nearby galaxy filaments and the Lya forest: confronting simulations and the UV background with observations
Bart P. Wakker, Audra K. Hernandez, David French +3
Simulations of the formation of large-scale structure predict that dark matter, low density highly ionized gas, and galaxies form 10 40 Mpc scale filaments. These structure are eas…
