摘要：

The discovery of 3:2 quasi-periodic oscillations (QPOs) in the ultra-luminous X-ray source NGC 1313 X-1 suggests it harbors an intermediate-mass black hole (IMBH). We test this numerically by modelling the 3:2 QPOs and the associated X-ray spectrum based on the epicyclic resonance model and a disk-corona model with large-scale magnetic fields generated by the Cosmic Battery mechanism. The combined QPO-frequency and spectral fitting indicates that the BH mass ranges from 2524 M-circle dot to 6811 M-circle dot confirming its IMBH nature, and the BH spin is probably higher than similar to 0.3.
