Expected Circular Polarization Detection by the Primordial Inflation Polarization Explorer (PIPER)

The Primordial Inflation Polarization Explorer (PIPER) is a balloon-borne mission searching for the polarization of the cosmic microwave background (CMB) created during the inflationary epoch of the early universe. Instruments will detect both linear and circular polarization (CP) with high precision. Though CP is not predicted in the CMB, it does exist in extragalactic radio sources. The objective of this study is to determine PIPER's expected CP detection from extragalactic radio sources. We will discuss the collection of CP detection from fifty-eight different sources and the expected flux when scaled using the PIPER beam and observing frequency. Also, we will present a CP sky map, which provides a sample of the intensity and location of these sources.
