Optimal and exact wide-angle power spectrum estimation
Noah Sailer, Kendrick Smith, Yurii Kvasiuk +2
What is the optimal power spectrum estimator on ultra-large scales where the plane-parallel approximation breaks down? Conventional estimators, such as the Yamamoto estimator, are…
First detection of the moving lens effect with ACT and DESI LS
Selim C. Hotinli, Kendrick M. Smith, Simone Ferraro +4
The moving lens effect is a secondary CMB anisotropy induced by the transverse motion of gravitational potentials. We develop a Fourier-space cross-spectrum estimator that retains…
Measurement of the galaxy-velocity power spectrum of DESI tracers with the kinematic Sunyaev-Zeldovich effect using DESI DR2 and ACT DR6
Edmond Chaussidon, Selim C. Hotinli, Simone Ferraro +49
Joint analyses of high-resolution CMB temperature maps with galaxy surveys provide a unique way to reconstruct the radial velocity field of the underlying matter distribution via t…
Inferring the Impacts of Baryonic Feedback from Kinetic Sunyaev-Zeldovich Cross-Correlations
Alex Laguë, Mathew S. Madhavacheril, Josh Borrow +4
The complex processes of baryonic feedback associated with galaxy evolution are still poorly understood, and their impact on the clustering of matter on small scales remains diffic…
Electrons Everywhere, All at Once: A Novel kSZ Estimator for Electron-Electron Correlations
Neha Anil Kumar, Mesut ÃalıÅkan, Selim C. Hotinli +2
Recent advancements in small-scale observations of the cosmic microwave background (CMB) have provided a unique opportunity to characterize the distribution of baryons in the outsk…
Velocity Reconstruction from KSZ: Measuring with ACT and DESILS
Selim C. Hotinli, Kendrick M. Smith, Simone Ferraro
The kinetic Sunyaev-Zel'dovich (kSZ) effect offers an indirect way to reconstruct large-scale cosmic velocities, by correlating high-resolution CMB temperature maps with galaxy sur…
