TL;DR
The EPIC-IM mission aims to measure primordial gravitational waves through CMB B-mode polarization, expanding scientific scope with increased aperture and sensitivity to extract comprehensive cosmological and Galactic information.
Contribution
This study introduces an intermediate aperture design for the EPIC mission, enhancing sensitivity and scientific capabilities beyond previous concepts.
Findings
Broader science case enabled by increased aperture.
High sensitivity allows detailed polarization and lensing measurements.
All-sky Galactic dust polarization data collected.
Abstract
Measurements of Cosmic Microwave Background (CMB) anisotropy have served as the best experimental probe of the early universe to date. The inflationary paradigm, inspired in part by the extreme isotropy of the CMB, is now a cornerstone in modern cosmology. Inflation has passed a series of rigorous experimental tests, but we still do not understand the physical mechanism or energy scale behind inflation. A general prediction of inflation and one that can provide certain insights into inflationary physics is a background of primordial gravitational waves. These perturbations leave a distinct signature in the CMB B-modes of polarization. The EPIC (Experimental Probe of Inflationary Cosmology) study team has investigated several CMB polarization mission concepts to carry out a definitive measurement of the inflationary B-mode polarization spectrum. In this report we study a mission with an…
