Observing axions through photon ring dimming of black holes
Kimihiro Nomura, Kaishu Saito, Jiro Soda
It is known that magnetic fields exist near black holes and photons can go around black holes due to strong gravity. Utilizing these facts, we can probe hypothetical pseudoscalar p…
Universal Hz stochastic gravitational waves from photon spheres of black holes
Kaishu Saito, Jiro Soda, Hirotaka Yoshino
We show that photon spheres of supermassive black holes generate high-frequency stochastic gravitational waves through the photon-graviton conversion. Remarkably, the frequency is…
invariant Fierz-Pauli massive gravity
Toshifumi Noumi, Kaishu Saito, Jiro Soda +1
We consider an invariant massive deformation of double field theory at the level of free theory. We study Kaluza-Klein reduction on and…
The matrix regularization for Riemann surfaces with magnetic fluxes
Hiroyuki Adachi, Goro Ishiki, Takaki Matsumoto +1
We consider the matrix regularization of fields on a Riemann surface which couple to gauge fields with a nonvanishing magnetic flux. We show that such fields are described as recta…
