Supernova Remnant LMC N 49
at Different Wavelengths

2 Micron Survey: Atlas Image, covering 5.0´ × 5.0´ on the sky, of the supernova remnant (SNR) N49 in the Large Magellanic Cloud (LMC). This appears to be the first near-infrared image of this SNR. The optical, X-ray, near-infrared and radio morphology for N49 all are in general agreement, with an incomplete shell covering nearly 1´ in diameter... N49 is also intriguing, with its possible association with the soft gamma-ray repeater SGR 0525-66 near the SNR's northern edge, however, this association has not yet been firmly established. SGRs are linked to isolated neutron stars, so if the association holds, this is further possible evidence of a massive stellar progenitor for this SNR...

ROSAT X-Ray Satellite: The grayscale shows the ROSAT X-ray image of the supernova remnant (SNR) N49 overlaid with contours of X-ray emission different levels. [X-rays are brightest at the eastern limb of the remnant.] The mass of gas in this molecular cloud is estimated to be only 104 solar masses.
