Beginning in mid-February 2008, the 1997-2007 online version of the Science Watch® newsletter, ESI-Topics.com, and in-cites.com, will all be featured together on the redesigned ScienceWatch.com. All previous content from the three sites will be permanently archived, and remain accessible from any existing bookmarks to the archived pages. No new content will be added to this site. Updates and new content (updated biweekly) are available at ScienceWatch.com now.

Black Holes Menu (Feb. 2004)

Black Holes

Methodology

Over the past decade, the hottest papers in black hole science have been led by the search for supermassive black holes in galactic nuclei and, not surprisingly, at the center of our galaxy in the vicinity of Sagittarius A*. Also dominating the list are theoretical models of advection-dominated black holes and the relationships between supermassive black holes, their host galaxies, and the dynamics of their accretion discs; other models concern stellar mass black holes that might generate gamma-ray bursts.

On the theoretical physics side of black holes, the list is dominated by the analysis of massless black holes in string theory and the line of exploration that leads from the entropy of these infinitesimal black holes to the construction of multi-dimensional membranes—known as d-branes—and quantum mechanics.

In the past two years, the top-20 list of hottest papers has been infiltrated by a host of papers discussing predictions of extra-dimensional scenarios in which these high-energy black holes are produced copiously in collisions between high-energy cosmic neutrinos and nucleons in the atmosphere and in proton-proton collisions at the Large Hadron Collider (LHC) being constructed at CERN. These papers discuss how these black holes would manifest themselves upon creation and the possibility of their detection at both the LHC and at high-energy cosmic ray observatories.

Methodology

To construct this database, papers were extracted based on title- keywords for Black Holes. The keywords used were as follows: 

black hole*

The baseline time span for this database is 1993-2003. The resulting database contained 4,844 ten-year papers (all); 1,079 two-year papers;  4,145 authors; 70 countries; 242 journals; and 1,331 institutions.

Rankings

Once the database was in place, it was used to generate the lists of top 20 papers, authors, journals, institutions, and nations, covering a time span of 1993-2003.

The top 20 papers are ranked according to total cites. Rankings for author, journal, institution, and country are listed in three ways: according to total cites, total papers, and total cites/paper. The paper thresholds used to determine scientist, institution, country, and journal rankings according to total cites/paper were as follows: 19, 28, 22, and 35, respectively. These thresholds correspond to the top 1% of authors, 5% of institutions, 50% of countries and 10% of journals by total papers.
