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 …

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 …

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 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 …

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 …

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

Ultralight axionlike particles (ALPs) are compelling dark matter candidates because of their
potential to resolve small-scale discrepancies between Λ CDM predictions and …

We present Capse. jl, a novel emulator that utilizes neural networks to predict Cosmic
Microwave Background (CMB) temperature, polarization and lensing angular power spectra …

We implement and explore high-dimensional generalized dark matter (HDGDM) with an
arbitrary equation of state as a function of redshift as an extension to Λ cold dark matter …
