The method for more effective detection of black hole star mass collisions was developed by a group of researchers who published their work on Nature Photonics. Black holes in a star’s mass are those black holes that result from a star’s mass compression caused by its own gravity.
Today, it is very difficult to detect collisions between two black holes of this type, as the signals from these collisions are strangled by so-called quantum noise, which develops and disrupts the operation of laser interferometers, devices that are commonly used to detect space “collisions.” The new method quenches this noise and makes measurements accurate, and according to the press release presented in the study, will be crucial for the next generation of detectors.
As one of the scientists involved in the project, Robert Ward, a researcher at the Australian National University School of Physics Research, explains, the current “detectors are so sensitive that only random quantum variability in the number of photons can disrupt mirrors to the extent that they hide the motion caused by this wave.
With the help of quantum presses specially designed by researchers at the Brazilian Institute, it has been possible to significantly strengthen the detection capabilities of, for example, the LIGO observatory in the United States and the Virgo observatory in Italy.
With this “upgrade” of the two detectors, and those that will be activated in the future, will be able to detect much more effectively every black hole in the universe, even those that have “only” the mass of stars, provided, of course, that they encounter other, and therefore not only those supermassive surrounded by deuterial discs and gases that “swallow.”
