Relation between the variations in the MgII $\lambda 2798$ emission-line and the 3000 Å continuum

Dongchun Zhu, Mouyuan Sun, Tinggui Wang

We investigate the relationship between the MgII $\lambda 2798$ emission-line and the 3000 Å continuum variations using a sample of 68 intermediate-redshift ($z\sim$ 0.65$-$1.50) br…
