Probing the thermal state of the intergalactic medium at with the transmission spikes in high-resolution Ly forest spectra
Prakash Gaikwad, Michael Rauch, Martin G. Haehnelt +13
We compare a sample of five high-resolution, high S/N Ly forest spectra of bright QSOs aimed at spectrally resolving the last remaining transmission spikes at…
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…
A New Measurement of the Temperature Density Relation of the IGM From Voigt Profile Fitting
Hector Hiss, Michael Walther, Joseph F. Hennawi +3
We decompose the Lyman-α (Lyα) forest of an extensive sample of 74 high signal-to-noise ratio and high-resolution quasar spectra into a collection of Voigt profiles. Absorbers loca…
A New Precision Measurement of the Small-Scale Line-of-Sight Power Spectrum of the Ly Forest
Michael Walther, Joseph F. Hennawi, Hector Hiss +4
We present a new measurement of the Ly forest power spectrum at using 74 Keck/HIRES and VLT/UVES high-resolution, high-S/N quasar spectra. We developed a custom…
Exploring the Thermal State of the Low-Density Intergalactic Medium at z=3 with an Ultra-High Signal-to-Noise QSO Spectrum
A. Rorai, G. D. Becker, M. G. Haehnelt +11
At low densities the standard ionisation history of the intergalactic medium (IGM) predicts a decreasing temperature of the IGM with decreasing density once hydrogen (and helium) r…
Characterizing the Pressure Smoothing Scale of the Intergalactic Medium
Girish Kulkarni, Joseph F. Hennawi, Jose Oñorbe +2
The thermal state of the intergalactic medium (IGM) at z < 6 constrains the nature and timing of cosmic reionization events, but its inference from the Ly-alpha forest is degenerat…
A New Method to Directly Measure the Jeans Scale of the Intergalactic Medium Using Close Quasar Pairs
Alberto Rorai, Joseph F. Hennawi, Martin White
Although the baryons in the intergalactic medium (IGM) trace dark matter on Mpc scales, small-scale (~100 kpc) fluctuations are suppressed by pressure support, analogous to the cla…
