Description
SNR 0540-69.3 is a ~1000 year-old-supernova remnant (SNR) located in the Large Magellanic Cloud. This remnant is associated with an active pulsar and a pulsar-wind nebula (PWN) and also possesses an oxygen-rich ejecta. Oftentimes, SNR 0540 is referred to as the Crab’s twin due to their similar properties, including the millisecond pulsar and PWN.
We study the continuum emission of the remnant’s pulsar and PWN. This emission sheds light on the emission mechanism and the complex particle distributions near the pulsar. However, previous studies have yielded conflicting results regarding the shape of the spectra.
We use data from the X-shooter spectrograph as well as MUSE (an integral-field spectrograph), both mounted on the VLT. These data provide the first NIR spectrum of this source along with the most complete coverage of the UV and optical range. With these data, we are also able to investigate the spatial differences in the spectral shape of the nebula spectrum.
In this talk, I present the preliminary results of the continuum emission analysis.
