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…
