We point out that although the observations discussed here are of black holes in x-ray binaries, dim (or dark) formation of black holes should also occur in massive progenitors that are not in binary systems, where the massive hydrogen envelope has been retained by ...

The aspect solution consists of a time history of the absolute pointing direction (RA, Dec, and Roll) of the Chandra HRMA, as well as the displacement of th ...
