No evidence for a low-mass black hole in Swift J1753.5-0127
No evidence for a low-mass black hole in Swift J1753.5-0127
We present high-resolution, time-resolved optical spectroscopy of the black hole X-ray transient Swift J1753.5−0127. Our optical spectra do not show features that we can associate with the companion star. However we do observe broad, double-peaked emission lines, typical of an accretion disc. We show that the mass of the compact object is likely >7.4 ± 1.2 M⊙, much higher than previous suggestions of a low-mass (<5 M⊙) black hole.

Abstract
We present high-resolution, time-resolved optical spectroscopy of the black hole X-ray transient Swift J1753.5−0127. Our optical spectra do not show features that we can associate with the companion star. However we do observe broad, double-peaked emission lines, typical of an accretion disc. We show that the mass of the compact object is likely >7.4 ± 1.2 M⊙, much higher than previous suggestions of a low-mass (<5 M⊙) black hole.
