Description
will summarize the main properties of young pulsar-powered supernova remnants,
and discuss in detail two of them, namely 3C 58 and SNR 0540-69.3. Both remnants are
classified as Crab-like supernova remnants, but as I will discuss, "Crab-like" may be
misleading. 3C 58 is located in our galaxy and was only recently identified in the optical
and near infrared.
It is actually only the third pulsar-wind nebula to be seen in the optical.
SNR 0540-69.3 is located in the Large Magellanic Cloud (LMC), and in contrast to for the Crab
and 3C 58, an outer shell produced by interaction of the forward shock with interstellar
gas has been observed. While the Crab pulsar wind shows variation, the pulsar wind nebula
of PSR B0540-69.3 is very dynamical even on large scales, which makes it unique and
interesting to study.
I will discuss new features revealed by detailed optical and X-ray studies.
