Description soft gamma repeaters (sgrs) are sources that produce short, repeated bursts of x- and gamma-radiation up to about 100 kev. three of them have been observed. one, sgr0525-66, is located in the n49 supernova remnant in the lmc. the second, sgr1806-20, is in the plerionic supernova remnant g10.0-0.3. the third, sgr1900+14, appears to be associated with both a strong iras source and a rosat soft x-ray source in the vicinity of g42.8+0.6, another galactic snr. it has been suggested that all three sgrs are young (<10000 yr) neutron stars in plerionic snrs, with strong magnetic fields, and that the synchrotron radiation of relativistic electrons in the magnetic fields of the nebulae should span the entire electromagnetic spectrum, with a spectrum similar to that of the crab. this hypothesis may be tested by measuring the electromagnetic spectra of the three sgrs over as broad a wavelength range as possible. sgr0525-66 is a soft x-ray source; sgr1806-20 is a radio and x-ray source. sgr1900+14 is an iras, 2.2 micron, and x-ray source. iso observations will define the spectra of these objects over a wavelength range where the synchrotron break energy is likely to occur, allowing estimates of the ages or magnetic field strengths to be made. iso will also be able to make the first observations of the polarizations of these objects.

Mission Description The Infrared Space Observatory (ISO) was the world's first true orbiting infrared observatory. Equipped with four highly-sophisticated and versatile scientific instruments, it was launched by Ariane in November 1995 and provided astronomers world-wide with a facility of unprecedented sensitivity and capabilities for a detailed exploration of the Universe at infrared wavelengths.
