Abstract

We present a spectral and timing analysis of X-ray emission from the actively accreting supermassive black hole (SMBH) in RX~J1301.9+2747 with prominent quasi-periodic eruptions (QPEs) using {\it ASCA, ROSAT, XMM-Newton}, and {\it NICER} observations. {\it NICER} detected renewed QPE activity from this source in 2024. We examined in detail the X-ray spectrum formation in this source during QPE outbursts applying the first-principal model, Bulk Motion Comptonization. We find an increase of the photon index Γ with a mass accretion rate Ṁ, the index saturation at Γsat=2.7± 0.1 at high Ṁ value during outburst peaks. Based on the derived Γ−Ṁ correlation, we apply the scaling technique for the first time to measure the black hole mass in RX~J1301.9+2747. The SMBH mass in this source was estimated to be between 4× 105 M⊙ and 7× 106 M⊙ for the inclination range from 0∘ to 70∘, which is adopted as a plausible range based on the AGN unified model assumption, applying HLX--1~ESO 243--49, OJ~287, and 1H~0707--495 as reference scaling sources. We also estimate a BH mass in RX~J1301.9+2747 applying a timing analysis, in which the Compton cloud size to be ∼ 1011 cm, estimated from the quasi-periodic oscillation frequency, ν∼ 10−4 Hz, indicates SMBH mass in RX~J1301.9+2747 is of order of 106 M⊙. Overall, the BH mass obtained by the scaling method in this source is consistent with previous measurements using other methods.
