【摘要】 在本文中我们给出了对M87的宽波束的射电观测结果。结合Ceccareli等人对室女座的红外观测资料(1982),我们论证了,为了便于统一解释射电及红外的观测资料,在M87的周围除了一个高温的晕(～10~8K)外,还可能存在一个微温的延伸晕(～10~5K)。这个微温的晕将会造成M87和高温晕的引力封闭。更多还原

【Abstract】 We show how combined large-beam infrared and radio observations towards M87 may be explained by assuming the existence of a large tepid (105K) dark matter halo surrounding the giant galaxy M87. The total mass of the more extended tepid halo is 1013 M⊙ Such a halo would be able to close the duster gravitationally.更多还原
