MERLIN在1666 MHz的观测中，在M82中心几百秒差距内探测到18个致密（<0.25弧秒）射电源。M82是众所周知的“星暴”星系，这些天体很可能是非常年轻的超新星遗迹。射电源的分布相对于星系中心是不对称的，我们认为这是由于当前的星星形成区域位于分子环内。
MERLIN observations at 1666 MHz detect 18 compact (< 0.25 arcsec) radio sources within the central few hundred parsecs of M82. M82 is well known as a ‘starburst’ galaxy, and it is probable that these objects are very young supernova remnants. The distribution of radio sources appears asymmetric with respect to the centre of the galaxy, and we suggest that this is due to the current region of star formation lying within a molecular ring.
