Scientists use radio waves to study distant quasars because quasars emit large amounts of radio waves but not much visible light.
Astronomers determine the size of quasars by analyzing the variability of their light. Quasars show rapid and dramatic changes in brightness over short periods, indicating that they must be very compact, likely smaller than our own solar system. By studying the time scales of these changes, astronomers can estimate the size of quasars.

Quasars typically have large redshifts, which indicate that they are moving away from us at high speeds. This redshift is due to the expansion of the universe and can help astronomers determine the distance and age of quasars.
Some astronomers study how matter behaves using particle accelerators.

the astronomers use Absolute magnitude

Astronomers use an auditory up on a hillside, and away from cities and pollution. So what i'm trying to say is that astronomers use an auditory to study the components of the universe.

they use tools.

Astronomers can use their eyes to study the stars. They can also use various telescopes that either refract, reflect, and detect exotic formations.
They don't (a whole lot) study stars for that purpose, as a typical star's life is much less than the life of the universe. They study galaxies. The oldest appearing galaxies also tend to be those farthest away, as measured by red shift. Farthest away of all are the quasars, which are still not fully understood.
