A spin-flip is a late stage in the evolution of a binary black hole.

The spin-flip could have been caused by absorption of a second black hole during a galaxy merger.

"The spin-flip will absorb the glow of the older material and will give us a signature that we can see."

Neutrino interactions such as vacuum oscillation and spin-flip are discussed.

Resonance condition for spin-flip is stated and derived.

Since the energy is additive in the number of flips, the probability "p" of having a spin-flip at each position is independent.

Units of time and distance are specified in terms of the frequency of the hydrogen spin-flip at 1,420 megahertz.

A widely discussed model for the origin of the X-shaped sources invokes a spin-flip of the supermassive black hole.

Since the vectors and are generically oriented in different directions, will point in a different direction than -a spin-flip.

A change in the rotation axis of a black hole due to a spin-flip would therefore result in a change in the direction of the jet.

In the final step of the rearrangement there is a spin-flip, termed intersystem-crossing (ISC) to provide paired electrons and a new sigma bond.

During the coalescence, the spin axis of the larger hole undergoes a sudden reorientation due to absorption of the smaller hole's orbital angular momentum-a "spin-flip."

It is believed that the wings are oriented in the direction of the jet prior to the spin-flip, and that the active lobes point in the current jet direction.

A black hole spin-flip occurs when the spin axis of a rotating black hole undergoes a sudden change in orientation due to absorption of a second (smaller) black hole.
