Consistency of Planck, ACT and SPT constraints on magnetically assisted recombination and forecasts for future experiments
Silvia Galli, Levon Pogosian, Karsten Jedamzik +1
Primordial magnetic fields can change the recombination history of the universe by inducing clumping in the baryon density at small scales. They were recently proposed as a candida…
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…
Constraints on CDM Extensions from the SPT-3G 2018 and Power Spectra
L. Balkenhol, D. Dutcher, P. A. R. Ade +117
We present constraints on extensions to the CDM cosmological model from measurements of the -mode polarization auto-power spectrum and the temperature--mode cross-power sp…
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…
Breaking the degeneracy between polarization efficiency and cosmological parameters in CMB experiments
Silvia Galli, W. L. Kimmy Wu, Karim Benabed +3
Accurate cosmological parameter estimates using polarization data of the cosmic microwave background (CMB) put stringent requirements on map calibration, as highlighted in the rece…
