Environment is one of the primary drivers of galaxy evolution; via multiple mechanisms, it
can control the critical process of transforming galaxies from star forming to quiescent …

We present a sample-variance-limited measurement of the temperature power spectrum
(TT) of the cosmic microwave background using observations of a∼ 1500 deg 2 field made …

We present a measurement of gravitational lensing over 1500 deg 2 of the Southern sky
using SPT-3G temperature data at 95 GHz and 150 GHz taken in 2018. The lensing …

Cosmic inflation provides a window to the highest energy densities accessible in nature, far
beyond those achievable in any realistic terrestrial experiment. Theoretical insights into the …

Transition Edge Sensors (TESs) are amongst the most sensitive cryogenic detectors and
can be easily optimized for the detection of massive particles or photons ranging from X-rays …

We obtain a reliable cosmological bound on the axion mass ma by (1) deriving the
production rate directly from pion-pion scattering data, which overcomes the breakdown of …

We report results from an analysis aimed at detecting the trispectrum of the kinematic
Sunyaev-Zel'dovich (kSZ) effect by combining data from the South Pole Telescope (SPT) …

In this paper we explore the existing tensions in the local cosmological expansion rate, H 0,
and amplitude of the clustering of the large-scale structure at 8 h-1 Mpc, σ 8, as well as …

Modified theories of gravity predict deviations from general relativity (GR) in the propagation
of gravitational waves (GWs) across cosmological distances. A key prediction is that the GW …

We describe the newest generation of the SLAC Microresonator RF (SMuRF) electronics, a
warm digital control and readout system for microwave-frequency resonator-based …
