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…
CosmoGAN: creating high-fidelity weak lensing convergence maps using Generative Adversarial Networks
Mustafa Mustafa, Deborah Bard, Wahid Bhimji +3
Inferring model parameters from experimental data is a grand challenge in many sciences, including cosmology. This often relies critically on high fidelity numerical simulations, w…
Measurement of the small-scale structure of the intergalactic medium using close quasar pairs
Alberto Rorai, Joseph F. Hennawi, Jose Oñorbe +6
The distribution of diffuse gas in the intergalactic medium (IGM) imprints a series of hydrogen absorption lines on the spectra of distant background quasars known as the Lyman-…
Constraining Reionization with the Lyman- Forest Power Spectrum: the Outlook after Planck
J. Oñorbe, J. F. Hennawi, Z. Lukić +1
The latest measurements of CMB electron scattering optical depth reported by Planck significantly reduces the allowed space of HI reionization models, pointing toward a later endin…
Statistical Detection of the HeII Transverse Proximity Effect: Evidence for Sustained Quasar Activity for 25 Million Years
Tobias M. Schmidt, Gabor Worseck, Joseph F. Hennawi +2
The HeII transverse proximity effect -- enhanced HeII Ly~transmission in a background sightline caused by the ionizing radiation of a foreground quasar -- offers a unique opport…
