Swift Observation of the Candidate Supermassive Black Hole Binary SDSS J153636.22+044127.0
Abstract
The X-Ray Telescope (XRT) and Ultraviolet/Optical Telescope (UVOT) on board the Swift satellite observed the candidate supermassive black hole binary SDSS J153636.22+044127.0 (hereafter, J1536; Boroson & Lauer 2009, arXiv:0901.3779v1) on 2009-02-04 and 2009-02-05 for total exposures of 3738 s and 3544 s, respectively. A ROSAT Faint Source Catalog source (1RXS J153635.6+044118; countrate 0.03 ± 0.01 s-1) with a positional error-circle radius of 18 arcsec was previously known to lie 12.7 arcsec from the SDSS coordinates.
