The mass and galaxy distribution around SZ-selected clusters

T. Shin, B. Jain, S. Adhikari +136

We present measurements of the radial profiles of the mass and galaxy number density around Sunyaev-Zel'dovich-selected clusters using both weak lensing and galaxy counts. The clus…

The Atacama Cosmology Telescope: Detection of the Pairwise Kinematic Sunyaev-Zel'dovich Effect with SDSS DR15 Galaxies

Victoria Calafut, Patricio A. Gallardo, Eve M. Vavagiakis +49

We present a 5.4 detection of the pairwise kinematic Sunyaev-Zel'dovich (kSZ) effect using Atacama Cosmology Telescope (ACT) and CMB observations in combination wi…

The Atacama Cosmology Telescope: Probing the Baryon Content of SDSS DR15 Galaxies with the Thermal and Kinematic Sunyaev-Zel'dovich Effects

Eve M. Vavagiakis, Patricio A. Gallardo, Victoria Calafut +49

We present high signal-to-noise measurements (up to 12) of the average thermal Sunyaev Zel'dovich (tSZ) effect from optically selected galaxy groups and clusters and estimate th…

The Atacama Cosmology Telescope: A Catalog of > 4000 Sunyaev-Zel'dovich Galaxy Clusters

M. Hilton, C. Sifón, S. Naess +146

We present a catalog of 4195 optically confirmed Sunyaev-Zel'dovich (SZ) selected galaxy clusters detected with signal-to-noise > 4 in 13,211 deg of sky surveyed by the Atacama…

The Atacama Cosmology Telescope: Component-separated maps of CMB temperature and the thermal Sunyaev-Zel'dovich effect

Mathew S. Madhavacheril, J. Colin Hill, Sigurd Naess +51

Optimal analyses of many signals in the cosmic microwave background (CMB) require map-level extraction of individual components in the microwave sky, rather than measurements at th…
