X-ray spectral scaling of black hole mass in quasi-periodic eruptive source RX J1301.9+2747
Lev Titarchuk, Elena Seifina, Vadim Arefiev +2
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 (Q…

Energy-independent X-Ray Polarization in 4U 1630-47 in the Intermediate State from Spectroscopy and Polarimetry
Elena Seifina, Lev Titarchuk, Paolo Soffitta +4
The IXPE mission enabled measurements of X-ray polarization in accreting binaries. The dependence of the X-ray polarization degree on the binary inclination and the optical depth o…
