The black hole in this quasar accretes around one solar mass per day onto an existing mass of ∼17 billion solar masses. In this process, the accretion disk alone releases a radiative energy of 2 × 10 41 W. If the quasar is not strongly gravitationally lensed, then its broad-line region is expected to have the largest physical and angular ...
A black hole is a region of spacetime where gravity is so strong that nothing, including light and other electromagnetic waves, is capable of possessing enough energy to escape it. Einstein's theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole. The boundary of no escape is called the event horizon.
20 de feb. de 2024 · The fastest-growing black hole ever recorded – devouring the equivalent of one sun every day – has been discovered by researchers at The Australian National University (ANU). Lead author Associate Professor Christian Wolf from ANU said it’s a record he doesn’t think will ever be beaten. “The incredible rate of growth also means a huge ...
18 de sept. de 2007 · IC 10 X-1 is a bright (Lx=10^38 ergs/s) variable X-ray source in the local group starburst galaxy IC 10. The most plausible optical counterpart is a luminous Wolf-Rayet star, making IC 10 X-1 a rare example of a Wolf-Rayet X-ray binary. In this paper, we report on the detection of an X-ray orbital period for IC 10 X-1of 34.4 hours. This result, combined with a re-examination of optical spectra ...

26 de ene. de 2010 · NGC 300 X-1 is a Wolf-Rayet/Black-Hole binary. We present VLT/FORS2 time-series spectroscopy of the Wolf-Rayet star #41 in the Sculptor group galaxy NGC 300. We confirm a physical association with NGC 300 X-1, since radial velocity variations of the HeII 4686 line indicate an orbital period of 32.3 +/- 0.2 hr which agrees at the 2 sigma level ...
18 de feb. de 2022 · Up until now, the best candidate for an explosion from the birth of a black hole has been the strange phenomenon known as long-duration gamma-ray bursts. First discovered in the 1960s by military satellites, these events have been hypothesized to result from jets accelerated to mindboggling speeds by newly formed black holes in collapsing stars.
