The rotational kinematic Sunyaev-Zeldovich (rkSZ) signal, imprinted on the cosmic microwave background (CMB) by the gaseous halos (spinning "atmospheres") of foreground galaxies, would be a novel probe of galaxy formation. Although the signal is too weak to detect in individual galaxies, we analyze the feasibility of its statistical detection via stacking CMB data on many galaxies for which the spin orientation can be estimated spectroscopically. We use an "optimistic" model, in which fully…

Cosmology with the Thermal-Kinetic Sunyaev-Zel'dovich Effect.

It is shown that with currently envisioned CMB missions the tkSZ effect can be detected and can be used to reconstruct large scale velocity fields, with no appreciable bias from either the kSZeffect or other extragalactic foregrounds, and the degeneracy due to uncertain gas physics will be significantly reduced.

Optimal filters for the moving lens effect

We assess the prospects for detecting the moving lens effect using cosmological surveys. The bulk motion of cosmological structure induces a small-scale dipolar temperature anisotropy of the cosmic

CMB-HD: Astro2020 RFI Response

CMB-HD is a proposed ultra-deep (0.5 uk-arcmin), high-resolution (15 arcseconds) millimeter-wave survey over half the sky that would answer many outstanding questions in both fundamental physics of



Measurement of the pairwise kinematic Sunyaev-Zeldovich effect with Planck and BOSS data

We present a new measurement of the kinetic Sunyaev-Zeldovich effect (kSZ) using Planck cosmic microwave background (CMB) and Baryon Oscillation Spectroscopic Survey (BOSS) data. Using the `LowZ

Detection of the pairwise kinematic Sunyaev-Zel'dovich effect with BOSS DR11 and the Atacama Cosmology Telescope

We present a new measurement of the kinematic Sunyaev-Zel'dovich effect using data from the Atacama Cosmology Telescope (ACT) and the Baryon Oscillation Spectroscopic Survey (BOSS). Using 600 square

Kinematic Sunyaev-Zel'dovich Effect with Projected Fields: A Novel Probe of the Baryon Distribution with Planck, WMAP, and WISE Data.

A novel estimator for the KSZ-large-scale structure cross-correlation based on projected fields is implemented: it does not require redshift estimates for individual objects, allowing KSZ measurements from large-scale imaging surveys, and will yield enormous signal-to-noise ratios when applied to upcoming high-resolution, multifrequency CMB surveys.

Constraining the rotational kinematic Sunyaev-Zel'dovich effect in massive galaxy clusters

We constrain the rotational kinematic Sunyaev-Zel'dovich (rkSZ) effect in Planck data using a sample of rotating galaxy clusters identified in the Sloan Digital Sky Survey (SDSS) . We extract

Kinetic Sunyaev–Zel’dovich effect in rotating galaxy clusters from MUSIC simulations

The masses of galaxy clusters are a key tool to constrain cosmology through the physics of large-scale structure formation and accretion. Mass estimates based on X-ray and Sunyaev--Zel'dovich

Using the kinematic Sunyaev-Zeldovich effect to determine the peculiar velocities of clusters of galaxies

We have investigated the possibility of inferring peculiar velocities for clusters of galaxies from the Doppler shift of scattered cosmic microwave background (CMB) photons. We find that if the core

Evidence of galaxy cluster motions with the kinematic Sunyaev-Zel'dovich effect.

Using high-resolution microwave sky maps made by the Atacama Cosmology Telescope, strong evidence for motions of galaxy clusters and groups via microwave background temperature distortions due to the kinematic Sunyaev-Zel'dovich effect is presented.

Kinetic Sunyaev-Zeldovich Effect from Halo Rotation

We discuss the kinetic Sunyaev-Zeldovich (SZ) contribution to cosmic microwave background (CMB) temperature fluctuations due to the coherent rotational velocity component of electrons within halos.

We present a simultaneous detection of gravitational magnification and dust reddening effects due to galactic haloes and large-scale structure. The measurement is based on correlating the brightness
