Measuring the thermal and ionization state of the low- IGM using likelihood free inference

Teng Hu, Vikram Khaire, Joseph F. Hennawi +6

We present a new approach to measure the power-law temperature density relationship and the UV background photoionization rate of the IGM base…

Improving IGM temperature constraints using wavelet analysis on high-redshift quasars

Molly Wolfson, Joseph F. Hennawi, Frederick B. Davies +3

The thermal state of the intergalactic medium (IGM) contains vital information about the epoch of reionization, one of the most transformative yet poorly understood periods in the…

A Novel Statistical Method for Measuring the Temperature-Density Relation in the IGM Using the - Distribution of Absorbers in the Ly Forest

Hector Hiss, Michael Walther, José Oñorbe +1

We present a new method for determining the thermal state of the intergalactic medium based on Voigt profile decomposition of the Ly forest. The distribution of Doppler paramete…

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…
