Suzaku observations find X-ray intraday variability of the blazar PKS 2155'304

Using the Suzaku satellite, astronomers have examined a very high energy (VHE) blazar known as PKS 2155'304. They found that the source exhibits an X-ray intraday variability, which could improve the understanding of its nature. The finding is reported in a paper published January 15 on arXiv.org.
