"Typically, these events are hard to observe. You get maybe a few observations at the beginning of the disruption when it's really bright. Our program is different in that it is designed to look at a few tidal events over a year to see what happens," CfA researcher Peter Maksym said."We saw this early enough that we could observe it at these very intense black hole accretion stages. We saw the accretion rate drop as it turned to a trickle over time.
Changes in what remains of the star destroyed in the TDE AT2022dsb are occurring over a timescale of days to months, meaning that ultraviolet spectroscopy and observations of these changes can tell astronomers more about the feasting black hole. They were also able to ascertain that this torus of gas that swirls around the black hole is around the size of our. The observations are taken from somewhere on the edge of the donut according to Maksym.

Hubble finds hungry black hole twisting captured star into donut shapeBlack holes are gatherers, not hunters. They lie in wait until a hapless star wanders by. When the star gets close enough, the black hole's gravitational grasp violently rips it apart and sloppily devours its gasses while belching out intense radiation.

Approaching optimal entangling collective measurements on quantum computing platforms - Nature PhysicsMulti-parameter metrology requires collective measurements on more than one copy of the same quantum state. Now, an optimal scheme for the estimation of qubit rotations has been demonstrated on superconducting and trapped-ion platforms.
