MAGNETIC-STRUCTURE OF THE REMNANT OF TYCHOS SUPERNOVA (SN-1572)

The local magnetic field of Tycho's supernova remnant (3C10) is organized into cell-like regions correlated with regions of relatively high polarized intensity. The size scale of the largest region of locally organized field is approximately 110 arcsec (1.33 pc), and an apparent size scale of the local field organization of the ambient interstellar medium is approximately 30 arcsec (0.36 pc). The direction of the mean field in regions of high local field organization within the SNR rim defined by high total intensity is generally radial.
