Crossing the Eddington Limit: Examining Disk Spectra at High Accretion Rates by Sutton, A., Swartz, D., Roberts, T., Middleton, M., Soria, Roberto, Done, C.

“…These "broadened disk (BD)" spectra are thought to indicate near- or mildly super-Eddington accretion onto stellar remnant black holes. Here we report that a sample of bright thermal-dominant black hole binaries, which have Eddington ratios constrained to moderate values, also show BD spectra in the 0.3-10 keV band at an order of magnitude lower luminosities. …”

Revealing the nature of the ULX and X-ray population of the spiral galaxy NGC 4088 by Mezcua, M., Fabbiano, G., Gladstone, J., Farrell, S., Soria, Roberto

“…We conclude that N4088-X1 is most likely a stellar remnant BH in an HMXB, probably fed by Roche lobe overflow, residing in a super-Eddington ultraluminous state. …”

Cygnus X-1 contains a 21-solar mass black hole-Implications for massive star winds by Miller-Jones, James, Bahramian, Arash, Orosz, J.A., Mande, I., Gou, L., Maccarone, T.J., Neijsse, C.J., Zhao, X., Ziółkowski, J., Reid, M.J., Uttley, P., Zheng, X., Byun, D.Y., Dodson, R., Grinberg, V., Jung, T., Kim, J.S., Marcote, B., Markoff, S., Rioja, M.J., Rushton, A.P., Russell, D.M., Sivakoff, G.R., Tetarenko, A.J., Tudose, V., Wilms, J.

“…These winds limit the masses of the stellar remnants (such as black holes) that the stars ultimately produce. …”
