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…
A Novel kinetic Sunyaev-Zel'dovich Estimator for Electron-Electron Correlations
Neha Anil Kumar, Mesut Çalışkan, 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…
Patchy Helium and Hydrogen Reionization from the Kinetic Sunyaev-Zel'dovich Effect and Galaxies
Neha Anil Kumar, Mesut Çalışkan, Selim C. Hotinli +3
Upcoming cosmic microwave background (CMB) experiments will measure temperature fluctuations on small angular scales with unprecedented precision, enabling improved measurements of…
Constraints on local primordial non-Gaussianity with 3d Velocity Reconstruction from the Kinetic Sunyaev-Zeldovich Effect
Alex Laguë, Mathew S. Madhavacheril, Kendrick M. Smith +2
The cosmic velocity field is an unbiased probe of the total matter distribution but is challenging to measure directly at intermediate and high redshifts. The large-scale velocity…
The Atacama Cosmology Telescope: Large-scale velocity reconstruction with the kinematic Sunyaev--Zel'dovich effect and DESI LRGs
Fiona McCarthy, Nicholas Battaglia, Rachel Bean +27
The kinematic Sunyaev--Zel'dovich (kSZ) effect induces a non-zero density-density-temperature bispectrum, which we can use to reconstruct the large-scale velocity field from a comb…
The Atacama Cosmology Telescope: Combined kinematic and thermal Sunyaev-Zel'dovich measurements from BOSS CMASS and LOWZ halos
Emmanuel Schaan, Simone Ferraro, Stefania Amodeo +55
The scattering of cosmic microwave background (CMB) photons off the free-electron gas in galaxies and clusters leaves detectable imprints on high resolution CMB maps: the thermal a…
Reconstructing CMB fluctuations and the mean reionization optical depth
P. Daniel Meerburg, Joel Meyers, Kendrick M. Smith +1
The Thomson optical depth from reionization is a limiting factor in measuring the amplitude of primordial fluctuations, and hence in measuring physics that affects the low-redshift…
Seven-Year Wilkinson Microwave Anisotropy Probe (WMAP) Observations: Galactic Foreground Emission
B. Gold, N. Odegard, J. L. Weiland +19
[Abridged] We present updated estimates of Galactic foreground emission using seven years of WMAP data. Using the power spectrum of differences between multi-frequency template-cle…
