Signatures of charged rotating regular black holes: quasinormal modes, grey-body factors and shadows
Abhisek Barman Maji
We construct and study possible astrophysical signatures of the rotating counterparts of two charged regular black holes, namely the Ayón--Beato--García (ABG) and Balart--Panotopou…
