A Robust Estimator for the Lyman- Forest 1D Power Spectrum at High Redshift
Molly Wolfson, Joseph F. Hennawi, Frederick B. Davies +1
The Lyman- (Ly) forest flux power spectrum is sensitive to a range of astrophysical and cosmological effects, including the thermal state of and large-scale fluctuatio…
The impact of varying inhomogeneous reionization histories on metrics of Ly opacity
Caitlin C. Doughty, Joseph F. Hennawi, Jose Oñorbe +2
The epoch of hydrogen reionization is complete by , but its progression at higher redshifts is uncertain. Measurements of Ly forest opacity show large scatter at , sug…
Measurement of the small-scale 3D Lyman- forest power spectrum
Marie Lynn Abdul-Karim, Eric Armengaud, Guillaume Mention +3
Small-scale correlations measured in the Lyman- (Ly) forest encode information about the intergalactic medium and the primordial matter power spectrum. In this article, we pr…
Forecasting constraints on the high-z IGM thermal state from the Lyman- forest flux auto-correlation function
Molly Wolfson, Joseph F. Hennawi, Frederick B. Davies +2
The auto-correlation function of the Lyman- (Ly) forest flux from high-z quasars can statistically probe all scales of the intergalactic medium (IGM) just after the epoch of…
Measurements of the Lyman- forest flux auto-correlation functions from the extended XQR-30 data set
Molly Wolfson, Joseph F. Hennawi, Sarah E. I. Bosman +14
Recently, the Lyman- (Ly) forest flux auto-correlation function has been shown to be sensitive to the mean free path of hydrogen-ionizing photons, , for simul…
Impact of Self-shielding Minihalos on the Ly Forest at High Redshift
Hyunbae Park, Zarija Lukić, Jean Sexton +2
Dense gas in minihalos with masses of can shield themselves from reionization for Myr after being exposed to the UV background. These self-shielded sy…
Reconstructing Lyman- Fields from Low-Resolution Hydrodynamical Simulations with Deep Learning
Cooper Jacobus, Peter Harrington, Zarija Lukić
Hydrodynamical cosmological simulations are a powerful tool for accurately predicting the properties of the intergalactic medium (IGM) and for producing mock skies that can be comp…
AMRIC: A Novel In Situ Lossy Compression Framework for Efficient I/O in Adaptive Mesh Refinement Applications
Daoce Wang, Jesus Pulido, Pascal Grosset +11
As supercomputers advance towards exascale capabilities, computational intensity increases significantly, and the volume of data requiring storage and transmission experiences expo…
