The Design and Integrated Performance of SPT-3G
J. A. Sobrin, A. J. Anderson, A. N. Bender +120
SPT-3G is the third survey receiver operating on the South Pole Telescope dedicated to high-resolution observations of the cosmic microwave background (CMB). Sensitive measurements…
Particle Physics with the Cosmic Microwave Background with SPT-3G
J. S. Avva, P. A. R. Ade, Z. Ahmed +85
The cosmic microwave background (CMB) encodes information about the content and evolution of the universe. The presence of light, weakly interacting particles impacts the expansion…
Sub-femtosecond absolute timing precision with a 10 GHz hybrid photonic-microwave oscillator
T. M. Fortier, C. W. Nelson, A. Hati +10
We present an optical-electronic approach to generating microwave signals with high spectral purity. By circumventing shot noise and operating near fundamental thermal limits, we d…
Asteroid Measurements at Millimeter Wavelengths with the South Pole Telescope
P. M. Chichura, A. Foster, C. Patel +141
We present the first measurements of asteroids in millimeter wavelength (mm) data from the South Pole Telescope (SPT), which is used primarily to study the cosmic microwave backgro…
Broadband, millimeter-wave antireflection coatings for large-format, cryogenic aluminum oxide optics
A. Nadolski, J. D. Vieira, J. A. Sobrin +86
We present two prescriptions for broadband (~77 - 252 GHz), millimeter-wave antireflection coatings for cryogenic, sintered polycrystalline aluminum oxide optics: one for large-for…
On-sky performance of the SPT-3G frequency-domain multiplexed readout
A. N. Bender, A. J. Anderson, J. S. Avva +86
Frequency-domain multiplexing (fMux) is an established technique for the readout of large arrays of transition edge sensor (TES) bolometers. Each TES in a multiplexing module has a…
Measurements of the E-Mode Polarization and Temperature-E-Mode Correlation of the CMB from SPT-3G 2018 Data
D. Dutcher, L. Balkenhol, P. A. R. Ade +118
We present measurements of the -mode () polarization power spectrum and temperature--mode () cross-power spectrum of the cosmic microwave background using data collec…
A Measurement of Gravitational Lensing of the Cosmic Microwave Background Using SPT-3G 2018 Data
Z. Pan, F. Bianchini, W. L. K. Wu +133
We present a measurement of gravitational lensing over 1500 deg of the Southern sky using SPT-3G temperature data at 95 and 150 GHz taken in 2018. The lensing amplitude relativ…
Performance and characterization of the SPT-3G digital frequency-domain multiplexed readout system using an improved noise and crosstalk model
J. Montgomery, P. A. R. Ade, Z. Ahmed +118
The third generation South Pole Telescope camera (SPT-3G) improves upon its predecessor (SPTpol) by an order of magnitude increase in detectors on the focal plane. The technology u…
Detection of Galactic and Extragalactic Millimeter-Wavelength Transient Sources with SPT-3G
S. Guns, A. Foster, C. Daley +119
High-angular-resolution cosmic microwave background experiments provide a unique opportunity to conduct a survey of time-variable sources at millimeter wavelengths, a population wh…
Performance of Al-Mn Transition-Edge Sensor Bolometers in SPT-3G
A. J. Anderson, P. A. R. Ade, Z. Ahmed +86
SPT-3G is a polarization-sensitive receiver, installed on the South Pole Telescope, that measures the anisotropy of the cosmic microwave background (CMB) from degree to arcminute s…
Cosmology From CMB Lensing and Delensed EE Power Spectra Using 2019-2020 SPT-3G Polarization Data
F. Ge, M. Millea, E. Camphuis +93
From CMB polarization data alone we reconstruct the CMB lensing power spectrum, comparable in overall constraining power to previous temperature-based reconstructions, and an unlen…
