© 2019 American Physical Society. A new branch of quasinormal modes for a massless scalar field propagating on the Schwarzschild spacetime was recently announced [D. Batic, M. Nowakowski, and K. Redway, Phys. Rev. D 98, 024017 (2018)PRVDAQ2470-001010.1103/PhysRevD.98.024017]. We review the quasinormal modes characterization and arguments and identify the flaws in their proof. Then, we preset explicit counterexamples to such arguments. Finally, we study the modes via alternative methods and do not find the new branch. We conclude against their interpretation.
