Thermal plasma in the giant lobes of the radio galaxy Centaurus A by O'Sullivan, S., Feain, I., McClure-Griffiths, N., Ekers, Ronald, Carretti, E., Robishaw, T., Mao, S., Gaensler, B., Bland-Hawthorn, J., Stawarz

“…We present a Faraday rotation measure (RM) study of the diffuse, polarized, radio emission from the giant lobes of the nearest radio galaxy, Centaurus A. After removal of the smooth Galactic foreground RM component, using an ensemble of background source RMs located outside the giant lobes, we are left with a residual RM signal associated with the giant lobes. …”

On the magnetic field through the Upper Centaurus-Lupus super bubble in the vicinity of the Southern Coalsack by Bhat, Ramesh, Andersson, B.

“…The Southern Coalsack is located in the interior of the Upper Centaurus-Lupus (UCL) super bubble and shows many traits that point to a much more energetic environment than might be expected from a dark, starless molecular cloud. …”
