Hot on the heels of my NGC253 paper, our paper showing that NGC300 X-1 is a Wolf-Rayet/Black Hole binary has beeb accepted. The mass of the black hole is 16-24 times more massive than our Sun, for inclinations of 60-75 degrees, making it the second heaviest stellar black hole known. The heaviest is IC10 X-1, which is also a known Wolf-Rayet/Black hole binary
