COLLOQUIUM
Institute of Physics Polish Academy of Sciences
 
 


The formal colloquium of the Institute of Physics, Polish Academy of Sciences it the main ongoing periodic series of lectures in physics and related science, of interest to members of the Institute. It is held from 1977. Colloquium speakers are primarily domestic and foreign scholars of established reputation, but also less-known physicists with remarkable and current scientific achievements. The colloquium is held once a month from September to June, usually at 3:15 PM on the last Tuesday of the month in the Auditorium of the Institute of Physics. Colloquia are open to the public, and are preceded by a coffee/the reception at the Institute.

For future information about the colloquia, pleace contact Prof. Dr. hab. Tomasz Dietl (dietl@ifpan.edu.pl), current chairman of the colloquium committee.

Abstract


      Quasars are the brightest continuous sources of light in the Universe. They may serve as "standard rulers", enabling the measurement of distances not available with other methods. I will review basic physical and observational properties of these objects. In particular I will concentrate on the black hole mass and luminosity measurement methods, and then on how the luminosity may provide clues for both the distances in and properties of the Universe.
