      We review the Banados–Teitelboim–Zanelli (BTZ) black hole solution in connection with the spinning string solution. We find a new exact solution, which can be related to the ($2+1$)-dimensional spinning point particle solution. There is no need for a cosmological constant, and so the solution can be upliftedto ($3 + 1$) dimensions. The exact solution in a conformally invariant gravity model, where the space–time is written as $g_{\mu\nu}=\omega^2\tilde{g}_{\mu\nu}$, is horizon free and has an ergo-circle, while $\tilde{g}_{\mu\nu}$ is the BTZ solution. The dilaton $\omega$ determines the scale of the model. It is conjectured that the conformally invariant non-vacuum BTZ solution will solve the boundary and causality problems which one encounters in spinning cosmic stringsolutions.

    • Continuous Article Publication

      Posted on January 27, 2016

      Since January 2016, the Journal of Astrophysics and Astronomy has moved to Continuous Article Publishing (CAP) mode. This means that each accepted article is being published immediately online with DOI and article citation ID with starting page number 1. Articles are also visible in Web of Science immediately. All these have helped shorten the publication time and have improved the visibility of the articles.
