| 英文摘要 | Abstract we investigated the power density spectrum (pds) and time lag of ultraluminous x-ray sources (ulxs) observed by xmm-newton. we determined the pdss for each ulx and found that five of them show intrinsic variability due to obvious quasi-periodic oscillations (qpos) of mhz–1 hz, consistent with previous reports. we further investigated these five ulxs to determine their possible time lag. the ulx qpos exhibit a soft time lag that is linearly related to the qpo frequency. we discuss the likelihood of the ulx qpos being type-c qpo analogs, and the time lag models. the ulxs might harbor intermediate-mass black holes if their? qpos are type-c qpo analogs. we suggest that the soft lag and the linearity may be due to reverberation. |
