Abstract:

This paper attempts to highlight the growth and development of dark energy literature and make the quantitative and qualitative assessment by way of analyzing various features of research output based on Web of Science database. A total of 5858 publications were published on dark energy, which received 157,581 citations during 1999-2011. The average number of publications per year was 450.62, and the average number of citations per publication was 26.90. The publications peaked in 2011 with 934 publications, and the highest number of citations (26,404) were received in 2003. There were 3857 (65.84%) single country publications from 74 countries and 2001 (34.16%) multi‑country collaborative publications.
