Some Vistas of Astronomical Discovery
As is the case with all epochs, the present one has its own characteristics—both in its political and in its scientific aspects. The science of 1960 is not the science of 1920 ; and, most emphatically, the astronomy of 1960 is not the astronomy of 1920. The differences are not entirely differences in instrumentation and in techniques ; even if the instruments of the 1950’s had been identical wi...
متن کاملInfluence of Society on Astronomical Discovery
I discuss the influence of society on astronomical discovery, concentrating on the last half century, during which astronomy evolved into a ‘big science’. Astronomy is observationally driven. The observational facilities needed to make paradigm-changing discoveries have become so sophisticated and expensive that only funding on a global scale is sufficient to enable their construction and opera...
متن کاملAccelerating the Rate of Astronomical Discovery with GPU-Powered Clusters
In recent years, the Graphics Processing Unit (GPU) has emerged as a low-cost alternative for high performance computing, enabling impressive speed-ups for a range of scientific computing applications. Early adopters in astronomy are already benefiting in adapting their codes to take advantage of the GPU’s massively parallel processing paradigm. I give an introduction to, and overview of, the u...
متن کاملAutomatic Optimized Discovery, Creation and Processing of Astronomical Catalogs
We present the design of a novel way of handling astronomical catalogs in Astro-WISE in order to achieve the scalability required for the data produced by large scale surveys. A high level of automation and abstraction is achieved in order to facilitate interoperation with visualization software for interactive exploration. At the same time flexibility in processing is enhanced and data is shar...
متن کاملAnalysis of Evolutionary Trends in Astronomical Literature using a Knowledge-Discovery System : Tétralogie
Databases of electronic abstracts provide a wealth of information for studies about covered topics, collaborative works, or short-term evolution trends. In this paper, we report a study of a subset of the ADS database (Astrophysics Data System) of astronomy abstracts, restricted to 6190 articles for which at least one of the authors is affiliated to French institution, in the range 1987 to 1996...
