DESI DR2 Results IV: Alcock-Paczyński Measurements from the Lyman Alpha Forest and Cosmological Constraints
DESI Collaboration, A. G. Adame, J. Aguilar +152
We present Alcock-Paczyński (AP) measurements from the full shape of Lyman- (Ly) forest correlation functions measured from the second data release (DR2) of the Dark Energy S…
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…
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…
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…
Forecast Cosmological Constraints with the 1D Wavelet Scattering Transform and the Lyman- forest
Hurum Maksora Tohfa, Simeon Bird, Ming-Feng Ho +2
We make forecasts for the constraining power of the 1D Wavelet Scattering Transform (WST) when used with a Lyman- forest cosmology survey. Using mock simulations and a Fisher ma…
