Radio-continuum observations of small, radially polarised Supernova Remnant J0519-6902 in the large Magellanic cloud
We report on new Australian Telescope Compact Array (ATCA) observations of SNR J0519-6902. The Supernova Remnant (SNR) is small in size (~8 pc) and exhibits a typical SNR spectrum with α = -0.53±0.07, with steeper spectral indices towards the northern limb of the remnant. SNR J0519-6902 con...

| description | We report on new Australian Telescope Compact Array (ATCA) observations of
SNR J0519-6902. The Supernova Remnant (SNR) is small in size (~8 pc) and
exhibits a typical SNR spectrum with α = -0.53±0.07, with steeper spectral
indices towards the northern limb of the remnant. SNR J0519-6902 contains a
low level of radially orientated polarisation at wavelengths of 3 and 6 cm,
which is typical of younger SNRs. A fairly strong magnetic field was
estimated to ~171µG. The remnant appears to be the result of a typical Type
Ia supernova, sharing many properties with another small and young Type Ia
LMC SNR, J0509-6731. [Projekat Ministarstva nauke Republike Srbije, br. 176005] |
