Strictly speaking it is not a dynamical BH but there is either a robust mass function or mass determination suggesting the presence of a BH

| Swift J1753.5-0127 remained in a low/hard X-ray state since its outburst in 2005 until 2016. In June 2015, it reached its lowest flux since its outburst (Neustroev2015). After 11 years in outburst, it started to decay towards its quiescent state around September 2016 (Russell2016). By early November 2016, the source was not detected in X-rays by Swift (Shaw2016a). There is a discrepance between the K2,Porb and M1 measured by Neustroev2014 and Shaw2016 The FWHM(Hα) scaling (Casares2015) coupled with the Porb (Zurita2008) strongly indicates a BH (Shaw2016). Gandhi2019 obtained a distance of 7.15+3.99-2.48 kpc from Gaia DR2. In 2023, Alabarta2023 reported a new outburst of the system which was detected in optical wavelengths with XB-NEWS (Russell2019). The system was reported to be back in quiescence in March 2024 (Alabarta2024) |
