The Simons Observatory (SO) is a ground-based cosmic microwave background (CMB) experiment sited on Cerro Toco in the Atacama Desert in Chile that promises to provide breakthrough discoveries in fundamental physics, cosmology, and astrophysics. Supported by the Simons Foundation, the Heising-Simons Foundation, and with contributions from collaborating institutions, SO will see first light in 2021 and start a five year survey in 2022. SO has 287 collaborators from 12 countries and 53 institutions, including 85 students and 90 postdocs. The SO experiment in its currently funded form ('SO-Nominal') consists of three 0.4 m Small Aperture Telescopes (SATs) and one 6 m Large Aperture Telescope (LAT). Optimized for minimizing systematic errors in polarization measurements at large angular scales, the SATs will perform a deep, degree-scale survey of 10% of the sky to search for the signature of primordial gravitational waves. The LAT will survey 40% of the sky with arc-minute resolution. These observations will measure (or limit) the sum of neutrino masses, search for light relics, measure the early behavior of Dark Energy, and refine our understanding of the intergalactic medium, clusters and the role of feedback in galaxy formation. With up to ten times the sensitivity and five times the angular resolution of the Planck satellite, and roughly an order of magnitude increase in mapping speed over currently operating ("Stage 3") experiments, SO will measure the CMB temperature and polarization fluctuations to exquisite precision in six frequency bands from 27 to 280 GHz. SO will rapidly advance CMB science while informing the design of future observatories such as CMB-S4.

Detection of Millimeter-Wavelength Flares from Two Accreting White Dwarf Systems in the SPT-3G Galactic Plane Survey
The first blind millimeter-wave search of the Galactic Plane found two roughly one-day flares from accreting white dwarf binaries, with isotropic luminosities near 10^31 erg/s.

In-Band Scattering and Absorption of Infrared Blocking Foam Filters for Millimeter-wave Cameras
Zotefoam LD24/LD15 filters cut in-band mm-wave scattering to <1% versus ~10% for Styrofoam, with batch variability up to 2 points, motivating SO SAT filter replacement.

Cosmological evolution with decaying dark matter: an integral-equation approach
CLASSIER-DDM evaluates generic two-body decaying dark matter perturbations via iterative integral equations at O(0.1%) accuracy and O(1 min) cost without a Boltzmann hierarchy or fluid approximation.

Direct detection of solar chameleons with electron recoil data from XENONnT
XENONnT electron-recoil data bound solar chameleons to log10 β_eff < −6.9, independent of the potential index n for inverse power-law chameleons at the dark-energy scale.

Neutrino Mass Constraints from kSZ Tomography
kSZ tomography will add little to neutrino mass constraints from Stage IV surveys unless the kSZ optical depth degeneracy is broken.

From Quantum Correlations to Inflationary Tracking Scalar Field Evolution
The author argues, via condensed-matter-style analogies, that the inflationary tracking condition emerges when the correlation length of primordial quantum degrees of freedom scales as a power of the Hubble radius.

GW170817 Viable Einstein-Gauss-Bonnet Inflation Compatible with the Atacama Cosmology Telescope Data
Einstein-Gauss-Bonnet inflation models with tuned small couplings can reproduce the ACT scalar spectral index and the Planck tensor-to-scalar ratio bound while keeping the gravitational wave speed within the GW170817 limit.
