Velocity Reconstruction with Autodifferentiable Forward Modelling and Optimization
We present an optimal estimator for the peculiar radial velocity field by jointly maximizing the posterior of the CMB temperature anisotropy given galaxy survey induced by the kinetic SZ effect.

Reconstruction of the non-linear cosmological density fields from galaxies
We develop a new method of reconstruction of the cosmological fields, such as dark matter and baryon density, from the observed luminous galaxies

KSZ Velocity Reconstruction with ACT and DESI‑LS using a Tomographic QML Power Spectrum Estimator
We perform a reconstruction of the radial velocity with the kSZ effect. We use the ACT-DR6 CMB data and the DESI-LS galaxy sample. We find a strong cross correlation detection signifficance (\(\sim 11 \sigma\))

QML-FAST - A Fast Code for Low-ℓ Tomographic Maximum Likelihood Power Spectrum Estimation
We present a novel implementation for the quadratic maximum likelihood (QML) power spectrum estimator for multiple correlated scalar fields on the sphere with computational optimizations making it tractable for low-ℓ analysis.

Two-field formalism for a neural network-enhanced non-Gaussianity search with halos
We introduce a new, neural-net-enhanced method for measuring the local non-Gaussianity \(f_{NL}\) from the dark matter halos with the estimator that reconstructs the local value of \(\sigma_8\) and the large-scale linear dark matter field
