Titolo: | Lights and Shadows on Galaxies Understanding | Autori: | D'ONOFRIO, MAURO RAMPAZZO, Roberto ZAGGIA, Simone |
Data pubblicazione: | 2016 | Titolo del volume in cui è pubblicato il poster: | From the Realm of the Nebulae to Populations of Galaxies | Serie: | ASTROPHYSICS AND SPACE SCIENCE LIBRARY | Numero: | 435 | Da pagina:: | 739 | Abstract: | With this book we neither aimed at tracing a history, even concise, of extragalactic astronomy nor at summarizing the vast panorama of scientific successes in this field of astrophysics. Our wish was to stimulate some distinguished researchers, via interviews in specific fields of extragalactic studies, at expressing their own convictions and perplexities about the progresses achieved in our understanding of galaxies across one century of research, if necessary emphasizing the scientific problems that still remain open. After about fifty interviews, we try in this chapter to delineate a picture underlying the facts and the views emerged from the presentations. The US of the second decade of XXth century has been the cradle where a bunch of scientists triggered a debate about the nature of spiral nebulæ, and put into discussion the size of The Galaxy set by Jacobus Kapteyn. The new research field, extragalactic astronomy, very soon reached the rank of a mature scientific branch of astrophysics “on the shoulder of giants” of the caliber of Hubble, Zwicky and Baade. However, it was only after WWII that the growth of extragalactic astronomy was overwhelming thanks to big investments in US and later on, for the worse economic conditions, also in some European countries and in Japan. In the last decade of the XXth century extragalactic astronomy assumed the today physiognomy of highly developed science branch in most of the advanced and emerging economies. The national level institutions and observing facilities characterizing the 1960-1980s decades boosted huge international collaborations and consortia, with hundreds of researchers involved with ground based telescopes located in the best observing sites. Space facilities with a complete wavelength coverage bypassed the limitations imposed by the Earth atmosphere providing a panchromatic view of galaxies. We refer to this as the Big Science era of extragalactic astronomy. | URI: | http://hdl.handle.net/20.500.12386/26594 | URL: | https://link.springer.com/chapter/10.1007%2F978-3-319-31006-0_10 | ISBN: | 978-3-319-31004-6 | DOI: | 10.1007/978-3-319-31006-0_10 | Bibcode ADS: | 2016ASSL..435..739D | Fulltext: | reserved |
