Discovery of a new gravitationally lensed QSO with broad absorption lines.
Abstract
We announce the discovery of a new bright gravitionally lensed QSO, HE 2149-2745. The object at z=2.033 presents two images separated by 1.7", with B magnitudes 17.3 and 19.0, respectively. Their spectra look identical within the measurement errors; in particular, both components display indistinguishable P Cygni-type emission/absorption complexes. Near to the line of sight to the brighter component, an extended source with R~19.8 is detected which could be responsible for the lensing. If it is a luminous galaxy (L~L*), we infer a probable redshift range of ~0.2-0.5.
