A Model of the Crab Nebula Derived from Dual-Frequency Radio Measurements
OWENS VALLEY RADIO OBSERVATORY PASADENA CA
Pagination or Media Count:
The total intensity and linearly polarized emission from the Crab Nebula Taurus A were synthesized to a resolution of approximately 1 arc-minute at both 1420 and 2880 MHz. From these data were calculated the spectral index, rotation measure, intrinsic position angle, and depolarization ratio distributions. Then, combined with a source model, the physical conditions within the supernova remnant were established. The strength and orientation of both the homogeneous and random components of the magnetic field were determined and a measurement of the thermal electron plasma distribution obtained.
