Discovery of Four X-Ray Quasars behind the Large Magellanic Cloud Academic Article uri icon

abstract

  • We present the discovery of four X-ray quasars (Zem = 0.26, 0.53, 0.61, and 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 second phase of the Optical Gravitational Lensing Experiment (OGLE-II); one of them was found by OGLE to be variable. We present the properties of the quasars and discuss their possible applications.
