Parsec-Scale Radio Jets
Quasars and active galaxies are the most powerful emitters of radiation in the universe. Modern radio telescope arrays have shown that the ultimate energy source resides in the central few parsecs of the galactic nucleus, and powers the emitting regions by way of two oppositely-directed relativistic jets of energy. This volume presents the latest observations and theories of these remarkable objects. Topics discussed include superluminal motions, the physics of jets and shock fronts in jets, related optical observations, and cosmic evolution. Particular attention is given to the "unified theories," which attempt to show that many of the phenomena in powerful extragalactic objects are different aspects of a single, basic mechanism; the main difference in their appearance is a result of their different orientation with respect to the observer.

High-Sensitivity Radio Astronomy
Enhanced sensitivity radio telescopes are producing dramatic results. An international conference was held in Jodrell Bank to take stock of these advances. This timely volume presents the review articles presented by a host of world experts who gathered at this meeting. We are shown how high sensitivity is advancing our understanding in radio spectral line analysis, radio continuum observations of galaxies, cosmology, pulsars, and radio emission from stars; what new and enhanced instruments are now available and those planned for the future. This volume provides graduate students and researchers with an up-to-date and wide-ranging review of the new and future research possible with high-sensitivity radio telescopes.
Postępy 2/1972
Jeden z archiwalnych numerów "Postępów Astronomii". Było to czasopismo naukowe, a później popularnonaukowe na temat astronomii i badań kosmosu, wydawane w latach 1953-1997 przez Polskie Towarzystwo Astronomiczne (PTA). W roku 1998 roku nastąpiło połączenie z czasopismem "Urania" i od tamtej pory ukazuje się jako "Urania - Postępy Astronomii". Obecnie "Urania - Postępy Astronomii" to nowoczesny i elegancki magazyn dla wszystkich miłośników kosmosu, wydawany wspólnie przez Polskie Towarzystwo Astronomiczne, zrzeszające zawodowych astronomów oraz Polskie Towarzystwo Miłośników Astronomii (PTMA), którego członkami są pasjonaci kosmosu.

Astrophysics, Astronomy and Space Sciences in the History of the Max Planck Society
This book provides the first comprehensive historical account of the evolution of scientific traditions in astronomy, astrophysics, and the space sciences within the Max Planck Society. Structured with in-depth archival research, interviews with protagonists, unpublished photographs, and an extensive bibliography, it follows a unique history: from the post-war relaunch of physical sciences in West Germany, to the spectacular developments and successes of cosmic sciences in the second half of the 20th century, up to the emergence of multi-messenger astronomy. It reveals how the Society acquired national and international acclaim in becoming one of the world’s most productive research organizations in these fields.

Postmodernizing the Holocaust
Marta Tomczok presents all Polish postmodern novels about the Holocaust, starting with “The First Splendor” by Leopold Buczkowski and ending with “The Suspected Dybbuk” by Andrzej Bart. She also presents their rich relationships with selected foreign-language prose, which intensified especially at the turn of the 20th and 21st centuries. The culmination of the entire trend is a discussion around two novels: “Tworki” by Marek Bieńczyk and “Fly Trap Factory” by Andrzej Bart, which reveals the aestheticizing and post-memorial profile of Polish postmodernization and its advantage over the historiosophical trend. This monograph is not only the first such collection of post-Holocaust postmodern novels, but also the first comprehensive study of postmodernism in the literature about the Holocaust, which, thanks to comparative analysis, tries to analyze and explain the circumstances of the appearance and later disappearance of this trend from cultural landscape of the world and Poland.
Very Long Baseline Interferometry
The quest for high resolution has preoccupied radio astronomers ever since radio waves were first detected from space fifty years ago. This venture was par ticularly stimulated by the discovery of quasars, and led to the development of interferometer techniques using baselines of transglobal dimensions. These meth ods have become known as Very Long Baseline Interferometry (VLBI). Arrays of radio telescopes situated all over the Earth (or even in space) are regularly used for researches in radio astronomy, reaching resolutions as small as a fraction of a milli arcsecond. The technique also allows the measurement of the positions of the radio telescopes to a few millimeters and so VLBI has bec...
