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…
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…
