Measuring Research Impact of Astronomers/Astrophysicists by using Astrophysics Data System Beta: a Powerful New Interface: a case study with Special Reference to Prof. Jayant V. Narlikar

Introduction: The paper highlights the qualitatively and quantitatively particular research productivity of Prof. Jayant V. Narlikar, a renowned Astrophysicist . He has total 472 research publications in fields of AA published during from 1961-2015.

Objective: The purpose of this paper is to provide an overview of citation-enhanced databases viz Astrophysics Data System Beta: A powerful new interface, which mainly used by Inter-University Centre for Astronomy and Astrophysics (IUCAA) users/visiting associates and to identify issues to be considered when they are used as a data source for performing citation analysis. The paper presents a valuable overview of new citation enhanced databases in the context of research evaluation.

Methodology: Scientometrics has been used to measure the publication productivity of Prof. Jayant V. Narlikar using Astrophysics Data System beta version: a powerful new interface in the field of AA.

Scope: The scope of the paper is limited to Astrophysics Data System Beta: A powerful new interface, a case study with special reference to Prof. Jayant V. Narlikar.

Result: The study suggests that citation-enhanced databases such as Astrophysics Data System (ADS) need to be examined carefully, with regard to both their potentialities and their limitations for citation analysis. The result indicates that most of the papers are published in peer reviewed journals having highest Impact factor. The average number of publications per year is 8.74 and maximum papers published during 1981-1990 and 1996-2000. His publications have total numbers of citations is 3516 and has maximum citations, 665 of his papers published during 1961-1970. He has maximum research collaborations with Prof. F. Hoyle (87 papers), Prof. G. Burbidge (38 papers), Prof. N. Wickramasinghe (22 papers) and Prof. T. Padmanabhan (21 papers).
