Cosmic Constraints: New Limits on Primordial Non-Gaussianity from DESI and Planck
Analysis
This research combines data from the Dark Energy Spectroscopic Instrument (DESI) and the Planck satellite to investigate primordial non-Gaussianity, offering a robust test of inflationary cosmology. The study's findings contribute to a deeper understanding of the early universe and its evolution.
Key Takeaways
- •Combines DESI quasar data and Planck CMB lensing to constrain primordial non-Gaussianity.
- •Provides tighter constraints on the deviation from Gaussianity in the early universe.
- •Offers a valuable contribution to understanding the physics of inflation.
