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…
Estimating Galactic Distances From Images Using Self-supervised Representation Learning
Md Abul Hayat, Peter Harrington, George Stein +2
We use a contrastive self-supervised learning framework to estimate distances to galaxies from their photometric images. We incorporate data augmentations from computer vision as w…
The Power Spectrum of the Lyman- Forest at z < 0.5
Vikram Khaire, Michael Walther, Joseph F. Hennawi +6
We present new measurements of the flux power-spectrum P(k) of the HI Lyman- forest spanning scales k ~ 0.001-0.1 s/km. These results were derived from 65 far ultraviole…
New Constraints on IGM Thermal Evolution from the Lyα Forest Power Spectrum
Michael Walther, Jose Oñorbe, Joseph F. Hennawi +1
We determine the thermal evolution of the intergalactic medium (IGM) over of cosmic time by comparing measurements of the Lyα forest power spectrum t…
Quantitative Constraints on the Reionization History from the IGM Damping Wing Signature in Two Quasars at z > 7
Frederick B. Davies, Joseph F. Hennawi, Eduardo Bañados +10
During reionization, neutral hydrogen in the intergalactic medium (IGM) imprints a damping wing absorption feature on the spectrum of high-redshift quasars. A detection of this sig…
Obtaining material identification with cosmic ray radiography
Christopher Morris, Konstantin Borozdin, Jeffrey Bacon +14
The passage of muons through matter is mostly affected by their Coulomb interactions with electrons and nuclei. The muon interactions with electrons lead to continuous energy loss…
