A Structure for Quasars

A model which combines all the main spectral features of AGN/quasars into a single structure. The structure is formed by an accretion disk wind. Elvis M. 2000, Astrophysical Journal, 545, 63 (Dec 10) (astro-ph/0008064) Color 2-D figure of structure (postscript)

3-D views of the quasar structure:

• From the side (postscript)
Through the cylindrical flow; spectrum shows narrow X-ray and UV absorption lines (NALs).

• From the top (postscript)


• Along the flow (postscript)
Spectrum shows Broad Absorption Lines (BALs)
