Over the past six decades
have passed since the time when the first quasars were discovered that the list
of high-galaxies with their fixture - a black hole at the galactic center
filled with more than 100,000 objects.
However, attempts to
produce a thorough census of powerful radiation sources have so far been
restricted to one fundamental problem. The fact that extreme brightness of
quasars, allowing them to see from a great distance, at the same time playing
on them,
and a cruel joke: dazzling sparkling quasars located in the
foreground, do not allow making out a dull and old quasars located behind them.
This means that astrophysicists have to study a population of objects with
significant differences between individual members on their distance, age,
brightness and type of radiation emitted.
However Astrophysics
Institute of Particle Astrophysics and Cosmology Kavli able to get around these
limitations and have created a unique algorithm that enables a thorough
analysis of large amounts of celestial objects, and as a quasars, as well as
populations of other objects located in space with a large spread in the
distance. Researchers presented their work in the Journal of The Astrophysical
Journal.
