Characterization of the Mid-Frequency Arrays for Advanced ACTPol
Steve K. Choi, Jason Austermann, James A. Beall +17
The Advanced ACTPol upgrade on the Atacama Cosmology Telescope aims to improve the measurement of the cosmic microwave background anisotropies and polarization, using four new dich…
Advanced ACTPol Low Frequency Array: Readout and Characterization of Prototype 27 and 39 GHz Transition Edge Sensors
Brian J. Koopman, Nicholas F. Cothard, Steve K. Choi +13
Advanced ACTPol (AdvACT) is a third generation polarization upgrade to the Atacama Cosmology Telescope, designed to observe the cosmic microwave background (CMB). AdvACT expands on…
Magnetic Sensitivity of AlMn TESes and Shielding Considerations for Next-Generation CMB Surveys
E. M. Vavagiakis, S. W. Henderson, K. Zheng +17
In the next decade, new ground-based Cosmic Microwave Background (CMB) experiments such as Simons Observatory (SO), CCAT-prime, and CMB-S4 will increase the number of detectors obs…
The Atacama Cosmology Telescope: The Two-Season ACTPol Sunyaev-Zel'dovich Effect Selected Cluster Catalog
Matt Hilton, Matthew Hasselfield, Cristóbal Sifón +41
We present a catalog of 182 galaxy clusters detected through the Sunyaev-Zel'dovich effect by the Atacama Cosmology Telescope in a contiguous 987.5 deg field. The clusters we…
