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 $>…
CMB-S4 Decadal Survey APC White Paper
Kevork Abazajian, Graeme Addison, Peter Adshead +222
We provide an overview of the science case, instrument configuration and project plan for the next-generation ground-based cosmic microwave background experiment CMB-S4, for consid…
The Atacama Cosmology Telescope: Cross-Correlation of CMB Lensing and Quasars
Blake D. Sherwin, Sudeep Das, Amir Hajian +28
We measure the cross-correlation of Atacama Cosmology Telescope CMB lensing convergence maps with quasar maps made from the Sloan Digital Sky Survey DR8 SDSS-XDQSO photometric cata…
Correlations in the (Sub)millimeter background from ACTxBLAST
Amir Hajian, Marco P. Viero, Graeme Addison +42
We present measurements of the auto- and cross-frequency correlation power spectra of the cosmic (sub)millimeter background at: 250, 350, and 500 um (1200, 860, and 600 GHz) from o…
The Atacama Cosmology Telescope: A Measurement of the Thermal Sunyaev-Zel'dovich Effect Using the Skewness of the CMB Temperature Distribution
Michael J. Wilson, Blake D. Sherwin, J. Colin Hill +35
We present a detection of the unnormalized skewness <T^3> induced by the thermal Sunyaev-Zel'dovich (tSZ) effect in filtered Atacama Cosmology Telescope (ACT) 148 GHz cosmic microw…
The Atacama Cosmology Telescope: Dusty Star-Forming Galaxies and Active Galactic Nuclei in the Southern Survey
Danica Marsden, Megan Gralla, Tobias A. Marriage +28
We present a catalog of 191 extragalactic sources detected by the Atacama Cosmology Telescope (ACT) at 148 GHz and/or 218 GHz in the 2008 Southern survey. Flux densities span 14-17…
Accounting for Correlations When Fitting Extra Cosmological Parameters
Yajing Huang, Graeme Addison, Charles Bennett
Current cosmological tensions motivate investigating extensions to the standard CDM model. Additional model parameters are typically varied one or two at a time, in a series of…
The Atacama Cosmology Telescope: Relation Between Galaxy Cluster Optical Richness and Sunyaev-Zel'dovich Effect
Neelima Sehgal, Graeme Addison, Nick Battaglia +33
We present the measured Sunyaev-Zel'dovich (SZ) flux from 474 optically-selected MaxBCG clusters that fall within the Atacama Cosmology Telescope (ACT) Equatorial survey region. Th…
CMB-S4 Science Case, Reference Design, and Project Plan
Kevork Abazajian, Graeme Addison, Peter Adshead +222
We present the science case, reference design, and project plan for the Stage-4 ground-based cosmic microwave background experiment CMB-S4.
The Atacama Cosmology Telescope: a measurement of the primordial power spectrum
Renée Hlozek, Joanna Dunkley, Graeme Addison +37
We present constraints on the primordial power spectrum of adiabatic fluctuations using data from the 2008 Southern Survey of the Atacama Cosmology Telescope (ACT). The angular res…
