She obtained her Masters and Ph.D. in Astronomy and Physics from Boston University in 1984 and 1987, respectively,〔BU alumni, http://www.bu.edu/dbin/astronomy/ast_alumni.php?id=2〕 working with thesis advisers Alan P. Marscher and Sheldon Lee Glashow. She was a NATO-NSF Postdoctoral Fellow at the Institute of Astronomy in Cambridge from 1987 to 1988, sponsored by Sir Martin Rees.〔Sir Martin Rees, http://en.wikipedia.org/wiki/Martin_Rees,_Baron_Rees_of_Ludlow〕 She joined the Physics Department at Princeton University in 1988, first as a Research Associate (1988 to 1989), then as an Instructor (1989 to 1990), and finally as an Assistant Professor (1990 to 1998). She joined the faculty at Bucknell University in 1998, and the faculty at the Pennsylvania State University at the Berks Campus in 1999. She is currently a Professor of Physics at Penn State University, Berks campus.〔PSU Berks campus faculty, http://www.berks.psu.edu/FacultyStaff/rDaly.htm〕 Daly conducts theoretical, phenomenological, and observational work in astrophysics. Her main areas of study are cosmology and extragalactic astrophysics. She is most well-known for her work on the expansion and acceleration histories of the universe, the use of these histories to determine the contents of the universe, and studies of the properties of supermassive black holes, e.g., as summarized.〔R. Daly, "A Decade of Dark Energy: 1998 - 2008," invited retrospective, in "Sources and Detection of Dark Matter and Dark Energy in the Universe: Proceedings of the 8th UCLA Symposium," AIP Conference Proceedings, Volume 1166, pp. 81-86 (2009), http://www.bk.psu.edu/faculty/daly/D09b.pdf〕 Non-specialists interested in this work can read about it in the popular literature, such as Sky & Telescope.〔R. Naeye, "Black-Hole Bonanza", Sky & Telescope, January 2010, available at http://www.skyandtelescope.com/astronomy-news/black-hole-bonanza/〕 Some key results, obtained in collaboration with Professor Stanislav George Djorgovski, are that the expansion and acceleration histories of the universe can be determined in a model-independent manner, which does not require that a theory of gravity be specified and does not depend upon the contents of the universe. The results indicate that the universe is accelerating at the present time, and was decelerating in the recent past. Daly has also shown that the properties of outflows from the vicinity of a supermassive black hole can be used to estimate the spin of the black hole. Her ongoing research into the acceleration of the universe and the properties of supermassive black holes is discussed in detail in her publications, linked at her website. ==References== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Ruth Agnes Daly」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
