SDSS J1553+0056: A BALQSO mimicking a Lyman-break galaxy

Abstract

Using the UVES echelle spectrograph at the ESO VLT we obtained high-resolution (R = 40 000) spectra of the object SDSS J1553+0056, which has been identified in the literature alternatively as a high-redshift quasar or as a Lyman-break galaxy (LBG). Although low-resolution spectra of SDSS J1553+0056 closely resemble those of LBGs, our high-resolution spectra allow us to identify this object unambiguously as a LoBAL quasar, probably belonging to the rare FeLoBALQSO class. Based on our spectrum we discuss how misidentifications of such objects from low-resolution spectra can be avoided.
