Cosmological Constraints from the eBOSS Lyman- Forest using the PRIYA Simulations
M. A. Fernandez, Simeon Bird, Ming-Feng Ho
We present new cosmological parameter constraints from the eBOSS Lyman- forest survey. We use a new theoretical model and likelihood based on the PRIYA simulation suite. PRIYA i…
A Multi-Fidelity Emulator for the Lyman- Forest Flux Power Spectrum
M. A. Fernandez, Ming-Feng Ho, Simeon Bird
In this work we extend our recently developed multi-fidelity emulation technique to the simulated Lyman- forest flux power spectrum. Multi-fidelity emulation allows interpolatio…
Effect of Separate Initial Conditions on the Lyman- Forest in Simulations
M. A. Fernandez, Simeon Bird, Phoebe Upton Sanderbeck
Using a set of high resolution simulations, we quantify the effect of species specific initial transfer functions on probes of the IGM via the Lyman- forest. We focus on redshif…
Cosmic Filaments from Cosmic Strings
M. A. Fernandez, Simeon Bird, Yanou Cui
Cosmic strings are generically predicted in many extensions of the Standard Model of particle physics. We propose a new avenue for detecting cosmic strings through their effect on…
