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…
Constraints on Cosmological Parameters from the 500 deg SPTpol Lensing Power Spectrum
F. Bianchini, W. L. K. Wu, P. A. R. Ade +68
We present cosmological constraints based on the cosmic microwave background (CMB) lensing potential power spectrum measurement from the recent 500 deg SPTpol survey, the most…
Measurements of B-mode Polarization of the Cosmic Microwave Background from 500 Square Degrees of SPTpol Data
J. T. Sayre, C. L. Reichardt, J. W. Henning +62
We report a B-mode power spectrum measurement from the cosmic microwave background (CMB) polarization anisotropy observations made using the SPTpol instrument on the South Pole Tel…
The SPTpol Extended Cluster Survey
L. E. Bleem, S. Bocquet, B. Stalder +135
We describe the observations and resultant galaxy cluster catalog from the 2770 deg SPTpol Extended Cluster Survey (SPT-ECS). Clusters are identified via the Sunyaev-Zel'dovich…
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…
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…
Galaxy Clusters Selected via the Sunyaev-Zel'dovich Effect in the SPTpol 100-Square-Degree Survey
N. Huang, L. E. Bleem, B. Stalder +74
We present a catalog of galaxy cluster candidates detected in 100 square degrees surveyed with the SPTpol receiver on the South Pole Telescope. The catalog contains 89 candidates d…
A Detection of CMB-Cluster Lensing using Polarization Data from SPTpol
S. Raghunathan, S. Patil, E. Baxter +126
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 u…
Fractional Polarisation of Extragalactic Sources in the 500-square-degree SPTpol Survey
N. Gupta, C. L. Reichardt, P. A. R. Ade +77
We study the polarisation properties of extragalactic sources at 95 and 150 GHz in the SPTpol 500 deg survey. We estimate the polarised power by stacking maps at known source p…
First M87 Event Horizon Telescope Results. VI. The Shadow and Mass of the Central Black Hole
The Event Horizon Telescope Collaboration
We present measurements of the properties of the central radio source in M87 using Event Horizon Telescope data obtained during the 2017 campaign. We develop and fit geometric cres…

The Event Horizon Telescope Collaboration
The Event Horizon Telescope (EHT) has mapped the central compact radio source of the elliptical galaxy M87 at 1.3 mm with unprecedented angular resolution. Here we consider the phy…
First M87 Event Horizon Telescope Results. IV. Imaging the Central Supermassive Black Hole
The Event Horizon Telescope Collaboration
We present the first Event Horizon Telescope (EHT) images of M87, using observations from April 2017 at 1.3 mm wavelength. These images show a prominent ring with a diameter of ~40…
