Simulation-Based Priors for HI Bias from Halo Occupation Physics
Debanjan Sarkar, Simon Foreman
Full-shape analyses of 21 cm intensity maps with the effective field theory of large-scale structure will require priors on HI bias parameters, and the standard choice of broad uni…

Mapping quark-level kinematics to hadrons in a new hybrid model of semileptonic meson decays
Philipp Horak, Robert Kowalewski, Tommy Martinov
The need to map parton-level processes to color-neutral hadrons in a way that respects quark-hadron duality arises in several areas of physics, including in the semileptonic decays…

Boosting HI-Galaxy Cross-Clustering Signal through Higher-Order Cross-Correlations
Eishica Chand, Arka Banerjee, Simon Foreman +1
After reionization, neutral hydrogen (HI) traces the large-scale structure (LSS) of the Universe, enabling HI intensity mapping (IM) to capture the LSS in 3D and constrain key cosm…
