Observations of Linear Polarization in the Galactic Centre Region

Polarized radio emission has been detected near Sgr A along the radio Arc and its extension above and below the galactic plane [1,2,3,4,5,6]. There is a compact source on the radio Arc (A) and the north-western (B) and south-eastern (C) “plumes” extending up to {b} = 0.6. Rotation measures (RM) at 10 GHz exceed 1000 rad m-2 at some places. The magnetic field direction is perpendicular to the galactic plane.

SYMMETRICAL STRUCTURES IN THE GALACTIC CENTRE REGION

Symmetrical structures do exist, in the Galactic Centre region, In this article we attempt, to summarize their properties and draw the attention of the scientific community to the advantages of taking them into account when working with models of the Centre of our Galaxy, Our work is corroborated by two new maps of the region at 10.7 GHz.
