The Atacama Cosmology Telescope: Two-Season ACTPol Lensing Power Spectrum
Blake D. Sherwin, Alexander van Engelen, Neelima Sehgal +43
We report a measurement of the power spectrum of cosmic microwave background (CMB) lensing from two seasons of Atacama Cosmology Telescope Polarimeter (ACTPol) CMB data. The CMB le…
An Open Source, FPGA-based LeKID readout for BLAST-TNG: Pre-flight Results
Samuel Gordon, Bradley Dober, Adrian Sinclair +17
We present a highly frequency multiplexed readout for large-format superconducting detector arrays intended for use in the next generation of balloon-borne and space-based sub-mill…
The Atacama Cosmology Telescope: Two-Season ACTPol Spectra and Parameters
Thibaut Louis, Emily Grace, Matthew Hasselfield +80
We present the temperature and polarization angular power spectra measured by the Atacama Cosmology Telescope Polarimeter (ACTPol). We analyze night-time data collected during 2013…
The Cosmology Large Angular Scale Surveyor
Kathleen Harrington, Tobias Marriage, Aamir Ali +33
The Cosmology Large Angular Scale Surveyor (CLASS) is a four telescope array designed to characterize relic primordial gravitational waves from inflation and the optical depth to r…
Instrumental performance and results from testing of the BLAST-TNG receiver, submillimeter optics, and MKID arrays
Nicholas Galitzki, Peter Ade, Francesco E. Angile +39
Polarized thermal emission from interstellar dust grains can be used to map magnetic fields in star forming molecular clouds and the diffuse interstellar medium (ISM). The Balloon-…
Optical modeling and polarization calibration for CMB measurements with ACTPol and Advanced ACTPol
Brian Koopman, Jason Austermann, Hsiao-Mei Cho +21
The Atacama Cosmology Telescope Polarimeter (ACTPol) is a polarization sensitive upgrade to the Atacama Cosmology Telescope. Located at an elevation of 5190 m, ACTPol measures the…
