[143.08] The Spatial Extent of Line-Emitting Regions in the Cloverleaf

The Cloverleaf QSO (H1413+1143) is a four-component gravitationally-lensed broad absorption line (BAL) QSO with an emission redshift of z=2.55. HST broad-band imaging shows the four components to be unresolved and separated by about 1 arcsec. These broad-band images primarily show H1413+1143's compact continuum-emitting region. However, by imaging in the line-emitting regions we can hope to use the natural lens present in the Cloverleaf to study the sizes of these more spatially-extended regions. Here we report on the results of such observations.
