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…
Pressure profiles and mass estimates using high-resolution Sunyaev-Zel'dovich effect observations of Zwicky 3146 with MUSTANG-2
Charles E. Romero, Jonathan Sievers, Vittorio Ghirardini +12
The galaxy cluster Zwicky 3146 is a sloshing cool core cluster at that in X-ray imaging does not appear to exhibit significant pressure substructure in the intracluster m…
The Simons Observatory: Astro2020 Decadal Project Whitepaper
The Simons Observatory Collaboration, Maximilian H. Abitbol, Shunsuke Adachi +280
The Simons Observatory (SO) is a ground-based cosmic microwave background (CMB) experiment sited on Cerro Toco in the Atacama Desert in Chile that promises to provide breakthrough…
Quantifying the Thermal Sunyaev-Zel'dovich Effect and Excess Millimeter Emission in Quasar Environments
Kirsten R. Hall, Nadia L. Zakamska, Graeme Addison +23
In this paper we probe the hot, post-shock gas component of quasar-driven winds through the thermal Sunyaev-Zel'dovich (tSZ) effect. Combining datasets from the Atacama Cosmology T…
Atacama Cosmology Telescope: Dusty star-forming galaxies and active galactic nuclei in the equatorial survey
Megan B. Gralla, Tobias A. Marriage, Graeme Addison +30
We present a catalog of 510 radio-loud active galactic nuclei (AGN, primarily blazars) and 287 dusty star-forming galaxies (DSFGs) detected by the Atacama Cosmology Telescope at $>…
Mass Variance from Archival X-ray Properties of Dark Energy Survey Year-1 Galaxy Clusters
A. Farahi, X. Chen, A. E. Evrard +76
Using archival X-ray observations and a log-normal population model, we estimate constraints on the intrinsic scatter in halo mass at fixed optical richness for a galaxy cluster sa…
Stellar mass as a galaxy cluster mass proxy: application to the Dark Energy Survey redMaPPer clusters
A. Palmese, J. Annis, J. Burgad +82
We introduce a galaxy cluster mass observable, , based on the stellar masses of cluster members, and we present results for the Dark Energy Survey (DES) Year 1 observation…
Dark Energy Survey Year 1 Results: Calibration of Cluster Mis-centering in the redMaPPer Catalogs
Y. Zhang, T. Jeltema, D. L. Hollowood +83
The center determination of a galaxy cluster from an optical cluster finding algorithm can be offset from theoretical prescriptions or -body definitions of its host halo center.…
