Current and Future Constraints on the Primordial Power Spectrum

Zachary Cheslog, Emily Finson, Amanda MacInnis +4

The primordial scalar power spectrum provides a powerful window onto early-universe physics, including a broad class of inflationary scenarios. These models often predict a charact…

The Simons Observatory: Commissioning of the Mid-Frequency Small Aperture Telescopes

Kathleen Harrington, Remington Gerras, Nicholas Galitzki +88

The Simons Observatory (SO) is a cosmic microwave background (CMB) survey experiment observing from an altitude of 5,200 m in the Atacama Desert in Chile. The SO Small Aperture Tel…

Model Predictive Scoring Shows Specific BAO Observations (not SNIa) Drives Tension

Tanveer Karim, Joshua S. Speagle, Renée Hložek

The recent analyses of DESI DR2 BAO, Planck CMB and various Supernovae datasets have shown preferences for evolving dark energy at various levels of significance, under frequentist…

Constraining primordial oscillations and inflationary particle production with Planck, ACT DR6, and DESI DR2

Simran K. Nerval, Renee Hlozek, Hidde T. Jense +1

Non-standard inflationary models often predict oscillatory features in the primordial power spectrum. We present constraints on general oscillatory templates for primordial power s…

Uniform Rolling: An LSST Observing Cadence Offering Sufficient Survey Uniformity for Comprehensive Cosmological Analysis

Boris Leistedt, Matthew R. Becker, Humna Awan +14

The Legacy Survey of Space and Time (LSST) that will be carried out by the NSF-DOE Vera C. Rubin Observatory promises to be the defining survey of the next decade, supplying unprec…

The Simons Observatory: Development of a Pipeline to Detect Rapid Transients in Time-Ordered Data

Justin Clancy, Carlo Baccigalupi, Carlo Bacciagalupi +15

We introduce a method for detecting astrophysical transients evolving on timescales of milliseconds to minutes using cosmic microwave background (CMB) survey telescopes. While prev…
