GGI Lectures on Large-Scale Structure Perturbation Theory (Effective Field Theory)
Mikhail M. Ivanov
These lecture notes introduce non-linear perturbation theory and effective field theory methods for modeling the large-scale distribution of galaxies, targeting undergraduate and e…
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…
A-BHPT-toolkit: Analytic Black Hole Perturbation Theory Package for Gravitational Scattering Amplitudes
Jovan Markovic, Mikhail M. Ivanov
Applications of effective field theory (EFT) and scattering amplitudes to gravitational problems have recently produced many unique results that advanced our understanding of the d…
Fresh Look at Neutrino Self-Interactions With the Lyman- Forest: Constraints from EFT and PRIYA Simulations
Adam He, Mikhail M. Ivanov, Simeon Bird +2
We present the first search for evidence of neutrino self-interaction with two new, state-of-the-art likelihoods for eBOSS Lyman- data. These are an effective field theory (EFT…
Bounds on Velocity-Dependent Dark Matter-Baryon Scattering from Large-Scale Structure
Adam He, Mikhail M. Ivanov, Rui An +2
We explore interacting dark matter (DM) models that allow DM and baryons to scatter off of each other with a cross section that scales with relative particle velocity. Using the ef…
