Cosmological Concordance in an Especially Opaque Universe: A Tentative Cosmological Detection of Physical Neutrino Mass in CDM
James M. Sullivan, Roger de Belsunce, Mikhail M. Ivanov
The measurement of the sum of neutrino masses is among the primary promises of precision cosmology, achievable by combining complementary early- and late-Universe probes. However,…
CORDEX-ML-Bench: A Benchmark for Data-Driven Regional Climate Downscaling -Experiment Design and Overview
Neelesh Rampal, José González-Abad, Henry Addison +34
Machine learning (ML) has emerged as a cost-effective approach to complement dynamical downscaling for producing high-resolution regional climate projections. However, the absence…
Analytic compression of the effective field theory of the Lyman-alpha forest
N. G. Karaçaylı, M. Ivanov, R. de Belsunce +3
The 1D flux power spectrum () of the Ly forest provides an exceptionally high-resolution probe of structure formation down to small scales ($k\approx1-10~\text{…
Climate Downscaling with Stochastic Interpolants (CDSI)
Erik Larsson, Ramon Fuentes-Franco, Mikhail Ivanov +1
Global climate projections rely on computationally demanding Earth System Models (ESMs), which are typically limited to coarse spatial resolutions due to their high cost. To obtain…
Bridging Simulations and EFT: A Hybrid Model of the Lyman-Alpha Forest Field
Roger de Belsunce, Boryana Hadzhiyska, Mikhail M. Ivanov
The Lyman-alpha (Lya) forest is a unique probe of cosmology and the intergalactic medium at high redshift and small scales. The statistical power of the ongoing Dark Energy Spectro…
Modeling the Cosmological Lyman- Forest at the Field Level
Roger de Belsunce, Mikhail M. Ivanov, James M. Sullivan +2
The distribution of absorption lines in the spectra of distant quasars, called the Lyman- (Ly-) forest, is a unique probe of cosmology and the intergalactic medium at high re…
Measuring and unbiasing the BAO shift in the Lyman-Alpha forest with AbacusSummit
Boryana Hadzhiyska, Roger de Belsunce, Andrei Cuceu +4
The currently observing Dark Energy Spectroscopic Instrument (DESI) places sub-percent constraints on the Baryon Acoustic Oscillations (BAO) scaling parameters from the Lyman- (…
The ACCEL2 Project: Precision Measurements of EFT Parameters and BAO Peak Shifts for the Lyman- Forest
Roger de Belsunce, Shi-Fan Chen, Mikhail M. Ivanov +4
We present precision measurements of the bias parameters of the one-loop power spectrum model of the Lyman-alpha (Lya) forest, derived within the effective field theory of large-sc…
