Multiple MgII Absorption Systems in the Lines of Sight to Quadruply Lensed Quasar H1413+1143

Katsuya Okoshi, Yosuke Minowa, Nobunari Kashikawa +6

We find multiple Mg II absorption systems at redshift z=1.66, 2.069, and 2.097 in the spatially resolved spectra of the quadruply gravitationally lensed quasar H1413+1143 utilizing…
