摘要：VHE g -ray emission was discovered from the high-frequency-peaked BL Lac object RGB J0152+017 in Nov. 2007. Observations with the X-ray satellite Swift (XRT, UVOT) and the optical telescope ATOM from Nov. 2007 to Jan. 2008 show flux variations on time scales of 10 days but with different variability patterns. This implies that at least 30% of the host-galaxy subtracted optical and UV flux is due to synchrotron emission from a compact component. Simultaneous observations of RGB J0152+017 by Swift/XRT and RXTE/PCA reveal that the spectra obtained from the non-imaging RXTE/PCA detector with its large field of view are contaminated by nearby bright X-ray sources.
