View Full Version : Now you see it, Now you don't..SN1987a pulsar?

SN1987a was the brightest supernova since Keplers in 1604. Post-explosion, searches have been made for its pulsar in the radio bands. The expectation is that eventually, discovery will be made, so intermittent funding of searches has been done, but detection can be hindered by absorption by the ejecta surrounding the remnant, and the morphology may be clumpy hindering things further. It has been shown that pulses from the Crab can be a million times stronger in signal strength over average pulse strength, so it may be possible to pick up a stray signal, but no regular conterpart.
Some signals have been seen in this try, but no periodicity, and the instrument, Parkes 64 meter was calibrated to the Large Cloud distance. If at first you don't succeed, try, try, again. SEE:https://arxiv.org/abs/1806.04062
