The existence of superluminal motions in the cores of radio sources,  the presence there of a black hole surrounded by an absorbing dust  torus, as inferred mostly from studies at other wavelengths, are now  accepted ideas. \u003cbr\u003e  Nevertheless, in spite of these efforts, there are many questions  still unanswered. For instance we do not know which mechanism produces  the huge amount of energy supplied to radio sources, how the jets  connecting the `engine' to the lobes are formed and collimated, which  of the differences observed among the various classes of radio sources  are apparent and which are real. \u003cbr\u003e  These and other related topics are discussed in this book.\u003c\/p\u003e \u003ch3\u003eDetails\u003c\/h3\u003e \u003cp\u003ePublished by: Springer\u003c\/p\u003e \u003cp\u003ePublication Date: 1996-09-30\u003c\/p\u003e \u003cp\u003eFormat: Hardcover\u003c\/p\u003e \u003cp\u003eISBN-13: 9780792341215\u003c\/p\u003e \u003cp\u003eDOI: 10.1007\/978-94-009-0295-4\u003c\/p\u003e \u003cp\u003eDimensions: 240cm x160cm\u003c\/p\u003e \u003cp\u003ePages: 631\u003c\/p\u003e ","brand":"Springer Netherlands","offers":[{"title":"Default Title","offer_id":46311755022476,"sku":"9780792341215","price":89.1,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/9545\/1788\/files\/9780792341215.jpg?v=1771512359","url":"https:\/\/lateknightbooks.com\/products\/9780792341215","provider":"Late Knight Books and Services, LLC","version":"1.0","type":"link"}
