Additional images of supernova remnant 1987A
The first detection of sn1987a at 12mm. Image by Manchester and Gaensler,
November 2001 (see
IAU Circular 7757).
ATNF researchers have used the Australia Telescope Compact Array near Narrabri to image the radio
remnant of SN 1987A at 12 mm wavelength (18.5 GHz) using all six antennas of the Compact Array to give a
maximum baseline of 6km. This image is the highest resolution image ever obtained with the Compact
Array. Astronomers will compare this image with images of the supernova remnant obtained at optical
wavelengths with the Hubble Space Telescope and X-ray wavelengths with the Chandra space X-ray
observatory.
(Image by Manchester et al, 1 August 2003).
These image was made possible by the upgrading of the ATCA under the Major National Research Facilities
Program to receive signals at millimetre wavelengths.
