    • Abstract

       

      In this work, we investigate the electromagnetic perturbation around a quantum-corrected Schwarzschild black hole. The complex frequencies of the quasinormal modes are evaluated by the third-order WKB approximation. The numerical results obtained showed that the complex frequencies depend on the quantum correction parameter a of a black hole, which the real parts and the magnitudes of the imaginary parts of quasinormal modes decrease with the increase in factor a. These conclusions show that the electromagnetic perturbation around the black hole oscillate and damp more slowly owing to the presence of the quantum correction parameter.

    • 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.
