The study found a relationship between the size of the central
object and the speed of the flickering produced by the disc, suggesting the physics of the accretion must be very similar around these different
astronomical objects despite them being completely different in
other ways, such
as size, age, temperature and gravity.
He adds that the technique will improve measurements of
astronomical distances, which build on the distances of nearby
objects such
as M33 to estimate the distances to
other «standard candles» farther away, such
as supernovae.
Now observing the mass of a black hole (at least indirectly) is easy: you measure how fast things orbit around it, just the same
as any
other massive
astronomical object.
For example, the Keck and Gemini telescopes offer high - resolution spectroscopic capabilities that, combined with theoretical analysis and computational modeling, can yield insight into the dynamics, chemical composition, and evolutionary state of the
objects imaged from space
as well
as a wealth of
other astronomical phenomena detected from the ground.
