MgII abs. toward SDSS QSOs with rotation measures

We probed the magnetic fields in high-redshift galaxies using excess extragalactic contribution to residual rotation measure (RRM) for quasar sightlines with intervening MgII...我们针对带有居间MgII吸收系统的类星体视线方向，借助残余旋转量度（residual rotation measure, RRM）中的过剩河外贡献，对高红移星系内的磁场开展了探测。
