Strong supernovae bounds on ALPs from quantum loops
Ricardo Z. Ferreira, M. C. David Marsh, Eike Müller
We show that in theories of axionlike particles (ALPs) coupled to electrons at tree-level, the one-loop effective coupling to photons is process dependent: the effective coupling r…

Gravitational Waves from Domain Walls in Pulsar Timing Array Datasets
Ricardo Z. Ferreira, Alessio Notari, Oriol Pujolas +1
We present a model-independent search for the gravitational wave background from cosmic domain walls (DWs) in the NANOGrav 12.5 years dataset and International PTA Data Release 2.…
