then its broad-line region is expected to have the largest physical and angular diameter occurring in the Universe and this will allow the Very Large Telescope Interferometer to image its rotation and measure its black-hole mass directly. This will be an important test for broad-line region size...
An 800-million-solar-mass black hole in a significantly neutral Universe at a redshift of 7.5. Nature, 553:473-476, January 2018.Ban˜ados, E., Venemans, B. P., Mazzucchelli, C., Farina, E. P., Walter, F., Wang, F. and Decarli, R. et al. (2018). An 800-million-solar...
Combined with the Hα velocity dispersion σline = 426 ± 1 km s−1, this lag determines a mass of about 10,000 M⊙ for the black hole (MBH). This mass is among the smallest central black hole masses reported, near the low end of expected masses for heavy ‘seeds...
Combined with the Hα velocity dispersion=426±1kms, this lag determines a mass of about 10,000for the black hole (). This mass is among the smallest central black hole masses reported, near the low end of expected masses for heavy 'seeds', and the best direct mass measurement for a ...
Observations of an ultraluminous quasar, SDSS J010013.02+280225.8, at redshift z = 6.30 show that the object has an optical and near-infrared luminosity a few times greater than those of previously known quasars at z > 6; the black hole that

An Earth mass black hole for instance would be smaller than a ping-pong ball. Now take something the size of 6 ping-pong balls and calculate the odds of it hitting anything in the vastness of space. Being so compact and depending on how fast they are moving in relation to the solar ...
