In the tunnelling prescription, radial null geodesics are used to visualize particles from behind the trapping horizon and the Hawking-like temperature has been calculated. On the other hand, in the Hamilton\u2013Jacobi formulation, quantum corrections have been incorporated by solving the Klein\u2013Gordon wave equation. In both the approaches, the temperature agrees at the semiclassical level.<\/jats:p>","DOI":"10.3390\/e18080287","type":"journal-article","created":{"date-parts":[[2016,8,8]],"date-time":"2016-08-08T10:14:38Z","timestamp":1470651278000},"page":"287","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Hawking-Like Radiation from the Trapping Horizon of Both Homogeneous and Inhomogeneous Spherically Symmetric Spacetime Model of the Universe"],"prefix":"10.3390","volume":"18","author":[{"given":"Subenoy","family":"Chakraborty","sequence":"first","affiliation":[{"name":"Department of Mathematics, Jadavpur University, Kolkata 700032, India"}]},{"given":"Subhajit","family":"Saha","sequence":"additional","affiliation":[{"name":"Department of Physical Sciences, Indian Institute of Science Education and Research Kolkata, Mohanpur 741246, India"}]},{"given":"Christian","family":"Corda","sequence":"additional","affiliation":[{"name":"Research Institute for Astronomy and Astrophysics of Maragha (RIAAM), Maragha 55134-441, Iran"},{"name":"Dipartimento di Fisica, Scuola Superiore di Studi Universitari e Ricerca \u201cSanta Rita\u201d, via Trasaghis 18\/E, Roma 00188, Italy"},{"name":"Austro-Ukrainian Institute for Science and Technology, Institut fur Theoretishe Physik, Technische Universit\u00e4t, Wiedner Hauptstrasse 8-10\/136, Wien A-1040, Austria"},{"name":"International Institute for Applicable Mathematics &amp; Information Sciences (IIAMIS), B.M.
