Abstract:
We present a multiwavelength spectral study of the quasar HE0359-3959, which has
been identified as an extreme radiating source at intermediate redshift (z = 1.5209). Along
the spectral range, the different ionic species give information about the substructures
in the broad line region. The presence of a powerful outflow with an extreme blueshifted
velocity of ~¿6,000 ± 500 km s¿1
is shown in the Civ¿1549 emission line. A prominent
blueshifted component is also associated with the 1900Å blend, resembling the one
observed in Civ¿1549. We detect a strong contribution of very the low¿ionization
lines, FeII and Near-Infrared Ca II triplet. We find that the physical conditions for
the low, intermediate, and high¿ionization emission lines are different, which indicate
that the emission lines are emitted in different zones of the broad line region. The
asymmetries shown by the profiles reveal different forces over emitter zones. The
high¿ionization region is strongly dominated by radiation forces, which also affect the
low and intermediate¿ionization emitter region, commonly governed by virial motions.
These results support the idea that highly radiating sources host a slim disk.
