Scientific paper
We request observations of the radio remnant of Supernova 1987A as part of our on-going monitoring and imaging campaigns. We propose to continue our programme of monitoring the flux of this source at 20/13/6/3 cm, and also propose to obtain the next epoch in our approximately annual sequence of 9 GHz super-resolved images. In addition, we request an imaging observation at 32 GHz, whcih will yield the highest quality image yet produced of this system. HST and Chandra imaging show increasing interaction of ejecta with circumstellar material. Deceleration of the radio shock front is now anticipated. ATCA 9 and 18 GHz data reveal that particle acceleration appears to be confined to a thick torus. We wish to follow the development of the radio emission as further interaction takes place with dense circumstellar matter.
