KSZ Velocity Reconstruction with ACT and DESI-LS using a Tomographic QML Power Spectrum Estimator
Anderson C. M. Lai, Yurii Kvasiuk, Moritz Münchmeyer
We perform kinetic Sunyaev-Zel'dovich (kSZ) velocity reconstruction on data from ACT DR6 and DESI-LS DR9. To estimate the cross-power between kSZ velocity reconstruction and galaxy…
Reconstruction of Continuous Cosmological Fields from Discrete Tracers with Graph Neural Networks
Yurii Kvasiuk, Jordan Krywonos, Matthew C. Johnson +1
We develop a hybrid GNN-CNN architecture for the reconstruction of 3-dimensional continuous cosmological matter fields from discrete point clouds, provided by observed galaxy catal…
Search for Isocurvature with Large-scale Structure: A Forecast for Euclid and MegaMapper using EFTofLSS
Daniel J. H. Chung, Moritz Münchmeyer, Sai Chaitanya Tadepalli
Isocurvature perturbations with a blue power spectrum are one of the natural targets for the future large scale structure observations which are probing shorter length scales with…
An optimal estimator for resonance bispectra in the CMB
Moritz Münchmeyer, P. Daniel Meerburg, Benjamin D. Wandelt
We propose an (optimal) estimator for a CMB bispectrum containing logarithmically spaced oscillations. There is tremendous theoretical interest in such bispectra, and they are pred…
