Abstract
We present the discovery of four X-ray quasars (z_em = 0.26, 0.53, 0.61, 1.63) located behind the Large Magellanic Cloud; three of them are located behind the bar of the LMC. The quasars were identified via spectroscopy of optical counterparts to X-ray sources found serendipitously by the Chandra X-ray Observatory satellite. All four quasars have archival VI photometry from the OGLE-II project; one of them was found by OGLE to be variable. We present the properties of the quasars and discuss their possible applicationsKeywords
