Measurement of gravitational lensing of the cosmic microwave background using SPT-3G 2018 data

Z. Pan, F. Bianchini, W. L. K. Wu, P. A. R. Ade et autres

This work presents the first gravitational lensing measurements with the 3G camera on the South Pole Telescope (SPT). Notably, it places constraints on key cosmological parameters consistent with those from SPT-SZ, SPTpol, ACT, and Planck.

Asteroid Measurements at Millimeter Wavelengths with the South Pole Telescope

P. M. Chichura, A. Foster, C. Patel, N. Ossa-Jaen et autres

Abstract We present the first measurements of asteroids in millimeter wavelength data from the South Pole Telescope (SPT), which is used primarily to study the cosmic microwave background (CMB). We analyze maps of two ∼270 deg2 sky regions near the ecliptic plane, …

The Design and Integrated Performance of SPT-3G

J. A. Sobrin, A. J. Anderson, B. A. Benson, D. Dutcher et autres

Abstract 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 of the temperature and polarization anisotropies of the CMB provide a powerful data set for constraining cosmology. …

Performance and characterization of the SPT-3G digital frequency-domain multiplexed readout system using an improved noise and crosstalk model

J. Montgomery, Peter A. R. Ade, Zeeshan Ahmed, Ethan Anderes et autres

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 used to read out and control these detectors, digital frequency-domain multiplexing (DfMUX), is conceptually the same …

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, Zeeshan Ahmed et autres

We present measurements of the $E$-mode ($EE$) polarization power spectrum and temperature-$E$-mode ($TE$) cross-power spectrum of the cosmic microwave background using data collected by SPT-3G, the latest instrument installed on the South Pole Telescope. This analysis uses observations of a $1500\text{ }\text{ …

A demonstration of improved constraints on primordial gravitational waves with delensing

P. A. R. Ade, Zeeshan Ahmed, M. Amiri, A. J. Anderson et autres

We present a constraint on the tensor-to-scalar ratio, $r$, derived from measurements of cosmic microwave background (CMB) polarization $B$-modes with ``delensing,'' whereby the uncertainty on $r$ contributed by the sample variance of the gravitational lensing $B$-modes is reduced by cross-correlating against a …

Optimal CMB Lensing Reconstruction and Parameter Estimation with SPTpol Data

M. Millea, C. Daley, T.-L. Chou, Ethan Anderes et autres

We perform the first simultaneous Bayesian parameter inference and optimal reconstruction of the gravitational lensing of the cosmic microwave background (CMB), using 100 deg$^2$ of polarization observations from the SPTpol receiver on the South Pole Telescope. These data reach noise levels as …

Event Horizon Telescope imaging of the archetypal blazar 3C 279 at an extreme 20 microarcsecond resolution

Jae-Young Kim, T. P. Krichbaum, Avery E. Broderick, Maciek Wielgus et autres

3C 279 is an archetypal blazar with a prominent radio jet that show broadband flux density variability across the entire electromagnetic spectrum. We use an ultra-high angular resolution technique – global Very Long Baseline Interferometry (VLBI) at 1.3 mm (230 GHz) – …

The SPTpol Extended Cluster Survey

L. E. Bleem, S. Bocquet, B. Stalder, Michael D. Gladders et autres

Abstract We describe the observations and resultant galaxy cluster catalog from the 2770 deg2 SPTpol Extended Cluster Survey (SPT-ECS). Clusters are identified via the Sunyaev–Zel’dovich (SZ) effect and confirmed with a combination of archival and targeted follow-up data, making particular use of …

Detection of CMB-Cluster Lensing using Polarization Data from SPTpol

S. Raghunathan, S. Patil, Eric J. Baxter, B. A. Benson et autres

We report the first detection of gravitational lensing due to galaxy clusters using only the polarization of the cosmic microwave background (CMB). The lensing signal is obtained using a new estimator that extracts the lensing dipole signature from stacked images formed by …
