Super-resolved 9 GHz images of the remnant of SN 1987A (SNR 1987A) obtained using the 6 km Australia Telescope Compact Array. The radio image fits within the inner optical recombination line ring and is aligned with it. Although the radio source is steadily increasing in brightness, it is expanding rather slowly. The east-west asymmetry is becoming more pronounced with time.
Flux densities for SNR 1987A measured at the ATCA since July 1990 are listed below. Each file contains the day number since the SN explosion (MJD - 46849.3), the central observing frequency in MHz, the integrated flux density of SNR 1987A in mJy and its estimated uncertainty in mJy, and the integrated flux density of J0536-6918 in mJy and its estimated uncertainty in mJy.
Measured flux densities for the radio remnant of SN 1987A in four bands, obtained using the ATCA. Note that recent data are preliminary only and in some cases are affected by instrumental problems.
