Fundamental Questions of Practical Cosmology

Dr. Yurij Baryshev (b. 1948) works as Senior Research Associate at the Astronomical Institute of St.Petersburg University, Russia. He has done research in various fields of extragalactic astronomy and cosmology, where his main research interest is relativistic astrophysics including cosmology and gravity physics. He has investigated Einstein's and Feynman's approaches to gravitation, active galactic nuclei, quasars, gravitational radiation, gravitational lensing by dark matter, and crucial cosmological tests. He has also studied the implications for cosmology of the recent discovery of the dark energy component and the fractal structure of the luminous matter distribution. He has been working as invited professor at the Rome University "La Sapienza" (Italy) and at the Lyon University (France). He has co-authored with P. Teerikorpi the book on the history of the Cosmological Principle Discovery of Cosmic Fractals (World Scientific 2002).

Dr. Pekka Teerikorpi (b.1948) works as Senior Research Associate at Tuorla Observatory of the Department of Physics and Astronomy of Turku University. He has done research in various fields of Galactic and extragalactic astronomy and practical cosmology, with special interest in the selection effects and biases influencing the determination of the cosmic distance scale and the value of the Hubble constant. He has also made excursions to the Milky Way (the rotation curve, interstellar dust), the realm of active galactic nuclei and the problem of the local detection of dark energy. He has co-authored with Yu. Baryshev the book on the history of the Cosmological Principle Discovery of Cosmic Fractals (World Scientific 2002) and has recently written, together with a few other astronomers and exobiologists the book The Evolving Universe and the Origin of Life - The Search for our Cosmic Roots (Springer 2009), telling about the history and spirit of our science.
