[51.11] Multiwavelength observations of the Loop I superbubble

K. Nishikida, D. N. Burrows (Penn State Univ.)

We present preliminary results of our multiwavelength observations of the Loop I superbubble, which is thought to be an old SNR reheated by more recent SNs/stellar winds from the Sco-Cen OB association. We are conducting a detailed geometrical and spectral study of Loop I in order to understand the interaction of the superbubble with its surrounding medium. Our study is based on selected ROSAT PSPC pointed observations, IRAS 100 \mum All Sky Survey map, 21 cm data obtained with the 140-foot telescope at Green Bank, and high-resolution interstellar NaI D observations carried out with the Coudé Feed telescope at KPNO.
