Scientific Output of AIMS Research Centres
The number of publications from AIMS Research Centres is rising strongly, in correspondence to the overall growth AIMS has experienced in recent years.
AIMS publications per year (non-cumulative)
The figure below illustrates this growth from 2010 until 2014. During this period the output has grown by an average factor of 1.8 per year. Between 20% to 30% of the scientific output is from visiting researchers.
Top 10 researchers that have worked at AIMS
The number of publications, citations and h-index are based upon their total research output during their career.

Romeel Davé* | American | Research Chair | 143 | 7911 | 48 |
Bruce Bassett* | South African | Senior Resident Researcher | 98 | 8446 | 39 |
Martin Kunz* | Swiss/German | Visiting Professor | 149 | 3352 | 32 |
Roberto Trotta | Italian | Research Fellow | 72 | 2127 | 28 |
Douw G. Steyn | South African | Senior Visiting Researcher | 88 | 1853 | 26 |

Citations
As the output of papers by AIMS has been rising, so has the cumulative number of citations AIMS’ papers have received (1624 on 30 June 2015). The indicator of interest though is the average number of citations per paper, which is 7 citations per paper. Another key indicator is the h-index, which is 19. This indicates that AIMS researchers have pub- lished 19 documents that have been cited at least 19 times.

Journals
The Source Normalised Impact per Paper (SNIP) is a comparative indicator of the impact of journals. SNIP is the ratio of a source’s average citation count per paper and the citation potential of its subject field. A SNIP value that is higher than one means that the journal has an above average SNIP for its field. A SNIP that is lower than one means that the journal has a below average SNIP for its field. If SNIP is equal to 1, the journal is absolutely average for its field.

Network Analysis
A network analysis maps the countries and institutions the AIMS researchers co-publish its papers with. The figure shows that they work mostly with institutes in South Africa, US, Canada and Europe. In Europe they mostly co-pub- lish with researchers from the UK, Switzerland, Spain, Germany and Italy

In addition to the above top 10 institutes AIMS co-publishes with, AIMS works together with many African institutes as well. The figure below shows the top 5 African institutes in terms of co-publications, which are all South African institutes. The only other African institute that is not in South Africa that AIMS co-published with frequently (17 papers) is Université de Yaounde I in Cameroon
