A new SNR candidate hidden in the luminous H2 region N159. Interstellar absorption lines as diagnostics for hidden SNRs. The supergiant shell LMC3

摘要

The observations for the first project were very noisy, and no publishable results were obtained. The observations obtained for 'Interstellar Absorption Lines as Diagnostics for Hidden super nova remnants (SNRs)' include two stars in the superbubble N144 and one star in the superbubble N11; the observations for 'The supergiant Shell LMC3' include two stars in LMC3. These spectra are useful and are being analyzed together with our ROSAT PSPC X-ray data of the associated superbubbles or supergiant shell in order to achieve a comprehensive understanding of the physical processes that produce the UV absorption lines and the diffuse X-ray emission.
