Millimeter-wave observations of Euclid Deep Field South using the South Pole Telescope

M. Archipley, A. Hryciuk, L.E. Bleem, K. Kornoelje et autres

Context. The South Pole Telescope third-generation camera (SPT-3G) has observed over 10 000 square degrees of sky at 95, 150, and 220 GHz (3.3, 2.0, 1.4 mm, respectively) and will significantly overlap the ongoing 14 000 square-degree Euclid Wide Survey. The Euclid …

SPT-3G D1: Quadratic-Estimator CMB Lensing Reconstruction and Cosmology

Y. Omori, W. L. K. Wu, Y. Nakato, F. Bianchini et autres

We present a map of the cosmic microwave background (CMB) lensing potential reconstructed from observations taken during the 2019 and 2020 seasons with the third-generation camera on the South Pole Telescope (SPT), covering the $1500\,{\rm deg}^{2}$ SPT-3G Main field, referred to as …

SPT-3G D1: Foreground-Robust Lensing Templates for Primordial Gravitational Wave Searches

Y. Nakato, W. L. K. Wu, Y. Omori, E. Anderes et autres

Gravitational lensing of the cosmic microwave background (CMB) generates B-mode polarization that acts as a source of contamination to searches for B modes generated by primordial gravitational waves (PGWs). The strongest constraint on PGW B modes is already significantly limited by lensing …

Characterization of the Polarization Beam Response of SPT-3G Using Point Sources

T. de Haan, M. Archipley, N. Huang, A.J Anderson et autres

Precise measurements of cosmic microwave background (CMB) polarization require rigorous control of instrumental systematics. For the South Pole Telescope’s third-generation camera (SPT-3G), which observes in three frequency bands roughly centered on 95, 150, and 220 GHz, accurate characterization of the beam—the instrument’s …

CMB Lensing Reconstruction Using Two Years of Temperature Data from the SPT-3G Summer Survey

K. Levy, S. Raghunathan, F. Guidi, Y. C. Li et autres

We present the first reconstruction of the cosmic microwave background (CMB) lensing potential from the SPT-3G Summer survey using two years of temperature data. The Summer survey has a total area of approximately 2640 deg$^2$, split into three fields covering 1210, 570, …

Galaxy Clusters Selected via the Sunyaev-Zel'dovich Effect in 5 year data from the SPT-3G Main Survey

L.E. Bleem, M. Klein, K. Kornoelje, S. Bocquet et autres

We report a new galaxy cluster catalog, selected using the thermal Sunyaev-Zel'dovich (SZ) effect, from 5 years of observations of the SPT-3G Main field. Drawn from arcminute-resolution data with white noise levels of 3.2, 2.5, and 8.9 $μ$K-arcmin at 95, 150, and …

Cross-correlation of SPT-3G D1 CMB lensing and DES Y3 galaxy lensing

A. Ouellette, Y. Omori, E. Anderes, A.J. Anderson et autres

Measurements of the weak lensing of galaxies and of the cosmic microwave background (CMB) provide direct probes of the cosmic matter density field, but the two observables are sensitive to different spatial scales, redshift ranges, and survey systematics. Their cross-correlation thus enables …

Millimeter-wave Detections of Symbiotic Stars in SPT and ACT Data

C. Tandoi, A. Foster, T. J. Maccarone, A.J. Anderson et autres

We present the results of a joint targeted search of candidate symbiotic stars at millimeter wavelengths using the South Pole Telescope (SPT) and the Atacama Cosmology Telescope (ACT). Candidates are selected from the New Online Database of Symbiotic Variables, restricting to objects …

Measurement of the Full Shape of the Thermal Sunyaev–Zel’dovich Power Spectrum from the South Pole Telescope and Herschel–SPIRE Observations

S. Raghunathan, P Ade, D. Anbajagane, Adam J. Anderson et autres

Abstract We present a measurement of the full shape of the power spectrum of the thermal Sunyaev–Zel’dovich (tSZ) effect down to arcminute scales using cosmic microwave background (CMB) data from the South Pole Telescope (SPT) over a roughly 100 deg 2 field. …

SPT-3G D1: Maps of the millimeter-wave sky from 2019 and 2020 observations of the SPT-3G Main field

W. Quan, E. Camphuis, C. Daley, N. Huang et autres

Maps of the sky in millimeter wavelengths contain rich information on cosmology through anisotropies of the cosmic microwave background (CMB). Creating multifrequency sky maps of anisotropies in the $I$, $Q$, and $U$ Stokes parameters is one of the first steps of CMB …

SPT-3G D1: Compton-$y$ maps using data from the SPT-3G and Planck surveys

A. S. Maniyar, F. Bianchini, W. L. K. Wu, S. Raghunathan et autres

We present thermal Sunyaev-Zel'dovich (tSZ) Compton-$y$ parameter maps constructed from two years (2019-2020) of observations with the South Pole Telescope (SPT) third-generation camera, SPT-3G, combined with data from the Planck satellite. Using a linear combination (LC) pipeline, we obtain a suite of …
