Scientific paper

A high-resolution X-ray image of the Local Group dwarf IC 1613 reveals that the principal source of X-ray emission in this direction arises in a background cluster of galaxies, as first suggested by Eskridge. In addition, however, we find a bright X-ray source coincident with the only known supernova remnant in this galaxy, S8. Extensive ground-based follow-up observations in the radio and optical regimes are reported. We confirm the nonthermal radio spectral index of the source and measure its extent to be ~3" at 20 cm. Imaging spectrophotometric observations taken with the multipupil spectrograph of the Special Astrophysical Observatory allow us to determine the density and velocity distribution of the gas in the remnant. The simultaneous presence of luminous X-ray and optical emission suggests a relatively young remnant in which the outward-moving shock has recently encountered dense material. We note that many of this object's properties are similar to those of the brightest optical remnant in the Large Magellanic Cloud, N49.
