Serendipitous Discovery of a Projected Pair of QSOs Separated by 4.5 arcsec on the Sky
International audience We present the serendipitous discovery of a projected pair of quasi-stellar objects (QSOs) with an angular separation of Δθ = 4.50 arcsec. The redshifts of the two QSOs are widely different: one, our program target, is a QSO with a spectrum consistent with being a narrow line...
