LATIS Data Release: Spectra of Galaxies, Redshifts, and Intergalactic Medium Tomography Maps
Andrew B. Newman, Gwen C. Rudie, Guillermo A. Blanc +8
We present the data release of the Ly Tomography IMACS Survey (LATIS), one of the largest optical spectroscopic surveys of faint high-redshift galaxies. The survey provides 7408…
LATIS: Galaxy-Environment Relations at Cosmic Noon and the Role of Sample Selection
Nima Chartab, Andrew B. Newman, Gwen C. Rudie +6
We investigate the environmental dependence of galaxy properties at using the Ly Tomography IMACS Survey (LATIS), which provides high-resolution three-dimensional map…
Small-scale Lyman alpha forest cosmology with PRIYA: Constraints from XQ100 and KODIAQ-SQUAD one-dimensional flux power spectra
Ming-Feng Ho, Mahdi Qezlou, Simeon Bird +4
We present a new cosmological analysis of the small-scale Lyman alpha forest 1D flux power spectrum (P1D) using high-resolution quasar spectra from XQ100 and KODIAQ-SQUAD, interpre…
Exploring the impact of AGN feedback model variations on the Lyman- Forest Flux Power Spectrum
Megan Pirecki, Megan Taylor Tillman, Blakesley Burkhart +2
We study the effects of varying different Active Galactic Nuclei (AGN) feedback parameters on the Lyman- (Ly) forest 1D transmitted flux power spectrum (P1D). We use the Cosm…
An AI super-resolution field emulator for cosmological hydrodynamics: the Lyman-α forest
Fatemeh Hafezianzadeh, Xiaowen Zhang, Yueying Ni +4
We extend our super-resolution and emulation framework for cosmological dark matter simulations to include hydrodynamics. We present a two-stage deep learning model to emulate high…
LATIS: Comparing Galaxy and IGM Tomography Maps as Tracers of Large-scale Structure and Protoclusters at
Andrew B. Newman, Nima Chartab, Mahdi Qezlou +11
We investigate the consistency of intergalactic medium (IGM) tomography and galaxy surveys as tracers of the cosmic web and protoclusters at . We use maps from the Ly$α…
LATIS: A Sample of IGM-selected Protoclusters and Protogroups at
Andrew B. Newman, Mahdi Qezlou, Gwen C. Rudie +11
The Ly Tomography IMACS Survey (LATIS) has produced large 3D maps of the intergalactic medium (IGM), providing a new window on the cosmic web at . A key advantage of L…
Design and optimization of neural networks for multifidelity cosmological emulation
Yanhui Yang, Simeon Bird, Ming-Feng Ho +1
Accurate and efficient simulation-based emulators are essential for interpreting cosmological survey data down to nonlinear scales. Multifidelity emulation techniques reduce simula…
Ten-dimensional neural network emulator for the nonlinear matter power spectrum
Yanhui Yang, Simeon Bird, Ming-Feng Ho +1
We present GokuNEmu, a ten-dimensional neural network emulator for the nonlinear matter power spectrum, designed to support next-generation cosmological analyses. Built on the Goku…
Hints of an Anomalous Lens Population towards the Galactic Bulge
Scott E. Perkins, Peter McGill, William A. Dawson +4
The dark and dynamic parts of the Galaxy, including the bulk shape and movement of the Galactic Bulge and characteristics of dark compact object populations, such as a hypothetical…
Ten-parameter simulation suite for cosmological emulation beyond CDM
Yanhui Yang, Simeon Bird, Ming-Feng Ho
We present Goku, a suite of cosmological -body simulations, and the corresponding 10-dimensional emulator, GokuEmu, for the nonlinear matter power spectrum. The simulations span…
