Scientific paper

We propose short exploratory observations of 3 Low-Ionization Broad Absorption Line Quasars with unusual properties. One is the most radio-loud LoBAL quasar known and only the second classical radio double BAL quasar known. Since RLQs are X-ray brighter than RQQs, this BAL quasar should be intrinsically X-ray bright. The second target has LoBAL troughs spanning at least 13000 km/s, with 90% absorption of its flux blueward of MgII. However, since most BAL troughs are saturated, its BAL gas column density may be the same as in less extreme LoBAL quasars; X-ray observations can test this possibility. The last target is a unique bright LoBAL quasar with stronger FeIII than FeII absorption; X-ray data probing absorption from different ionization states will help understand its unique spectrum.
