Primordial non-Gaussianity constraints on dissipative inflation
Santiago Agüà Salcedo, Thomas Colas, Petar Suman +3
Dissipative effects appear in many early-Universe scenarios, yet their universal observational signatures and systematic confrontation with data remain largely unexplored. We emplo…
Searching for Cosmological Collider in the Planck CMB Data II: collider templates and Modal analysis
Petar Suman, Dong-Gang Wang, Wuhyun Sohn +2
Signatures of massive particles during inflation are highly informative targets for cosmological experiments. With recent progress on both theoretical and observational frontiers,…
A Modal Approach to Constrain Inflation through Numerical Bispectra
Bowei Zhang, E. P. S. Shellard, James R. Fergusson
Constraining inflationary models with high precision bispectra across broad parameter ranges is a challenging task, requiring intensive computations at all stages, first, predictin…
The Simons Observatory: forecasted constraints on primordial gravitational waves with the expanded array of Small Aperture Telescopes
The Simons Observatory Collaboration, I. Abril-Cabezas, S. Adachi +479
We present updated forecasts for the scientific performance of the degree-scale (0.5 deg FWHM at 93 GHz), deep-field survey to be conducted by the Simons Observatory (SO). By 2027,…
How Significant are Cosmological Collider Signals in the Planck Data?
Petar Suman, Dong-Gang Wang, Wuhyun Sohn +2
The search for primordial non-Gaussianities (PNG) is theoretically well motivated but remains observationally challenging. Tight constraints with low significance for the standard…
The Simons Observatory: Science Goals and Forecasts for the Enhanced Large Aperture Telescope
The Simons Observatory Collaboration, M. Abitbol, I. Abril-Cabezas +419
We describe updated scientific goals for the wide-field, millimeter-wave survey that will be produced by the Simons Observatory (SO). Significant upgrades to the 6-meter SO Large A…
