Exotic PeVatrons as sources of ultra-high-energy gamma rays

Andrea Addazi, Salvatore Capozziello, Qingyu Gan

We explore novel classes of exotic astrophysical sources capable of producing ultra-high-energy gamma rays extending beyond the PeV scale, motivated by quantum gravity scenarios an…

Gravitational waves in minimal Maxwell $f (R)$ gravity

Salvatore Capozziello, Qingyu Gan

We discuss the conversion mechanism from scalar field to gravitational waves in magnetic background in $f (R)$ gravity minimal coupled to the Maxwell electrodynamics. Applying the c…
