First, we extend the metric with spherical symmetry to the one of rotating Kerr-like black holes and derive the null geodesics with a circular orbit near the horizon of the black hole. Then, we plot the shadows of black holes with different values for the deviation parameter. It is found that the size of the shadow shrinks with the increase in the deviation parameter, while the shape of the shadow becomes more deformed. In particular, by comparing with the shadow a Bardeen black hole and Hayward black hole with the same parameter values, we find that, in general, the shadows of black holes with Minkowski cores have larger deformations than those with de Sitter cores, which potentially provides a strategy to distinguish these two sorts of regular black holes with different cores by astronomical observation in the future.<\/jats:p>","DOI":"10.3390\/sym14112415","type":"journal-article","created":{"date-parts":[[2022,11,16]],"date-time":"2022-11-16T02:31:27Z","timestamp":1668565887000},"page":"2415","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":24,"title":["The Shadows of Regular Black Holes with Asymptotic Minkowski Cores"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7392-8641","authenticated-orcid":false,"given":"Yi","family":"Ling","sequence":"first","affiliation":[{"name":"Institute of High Energy Physics, Chinese Academy of Sciences, Beijing 100049, China"},{"name":"School of Physics, University of Chinese Academy of Sciences, Beijing 100049, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0386-6307","authenticated-orcid":false,"given":"Meng-He","family":"Wu","sequence":"additional","affiliation":[{"name":"School of Mathematics, Physics and Statistics, Shanghai University of Engineering Science, Shanghai 201620, China"},{"name":"Center of Application and Research of Computational Physics, Shanghai University of Engineering Science, Shanghai 201620, China"}]}],"member":"1968","published-online":{"date-parts":[[2022,11,15]]},"reference":[{"key":"ref_1","unstructured":"The Event Horizon Telescope Collaboration, Akiyama, K., Alberdi, A., Alef, W., Asada, K., Azulay, R., Baczko, A.-K., Ball, D., Balokovi\u0107, M., and Barrett, J.
