  • We present detailed analyses of the absorption spectrum seen in QSO 2359-1241 (NVSS J235953-124148). Keck HIRES data reveal absorption from 20 transitions arising from He I, Mg I, Mg II, Ca II, and Fe II. Hubble Space Telescope data show broad absorption lines (BALs) from Al III ?1857, C IV ?1549, Si IV ?1397, and N V??1240. Absorption from excited Fe II states constrains the temperature of the absorber to 2000 T 10,000 K and puts a lower limit of 105 cm-3 on the electron number density… CONTINUE READING
