This paper will describe the Marshall Space Flight Center's Solar Ultraviolet Magnetograph (SUMI) sounding rocket program, with emphasis on the polarization characteristics of the VUV optics and their spectral, spatial and polarization resolution. SUMI's first flight (7/30/2010) met all of its mission success criteria and this paper will describe the data that was acquired with emphasis on the ...

We monitored the superluminal QSO 3C 345 at three epochs during a one-year We imaged the radio source both in total and in polarized intensity. In the images at 5 and 8.4 GHz, the jet emission is traced up to 20 milliarcseconds (mas) from the jet core. In the 15 and 22 GHz images, we identify several enhanced emission regions moving at apparent speeds of 5c. Images of the linear polarized emiss...

We present total-intensity and linear-polarization observations made with the Very Large Array at λ20 and 6 cm of a representative sample of 42 radio galaxies and quasars selected from the Molonglo Complete Sample. The sources have been chosen to be of large size to probe the depolarizing medium on these scales using our present data and later with observations at lower frequencies with the Gia...

By suitably adding rightand left-hand circularly polarized helicon waves in a cylinder, it is possible, in principle, to form linearly polarized modes, contrary to the notion that whistler waves must be circularly polarized. The plane-polarized component is accompanied by a left-hand circularly polarized component which vanishes on axis but becomes important at large radii. The field lines of t...
