Magnetohydrodynamics predicts heavy-tailed distributions of axion-photon conversion
Pierluca Carenza, Ramkishor Sharma, M. C. David Marsh +2
The interconversion of axionlike particles (ALPs) and photons in magnetised astrophysical environments provides a promising route to search for ALPs. The strongest limits to date o…
Batchelor, Saffman, and Kazantsev spectra in galactic small-scale dynamos
Axel Brandenburg, Hongzhe Zhou, Ramkishor Sharma
The magnetic fields in galaxy clusters and probably also in the interstellar medium are believed to be generated by a small-scale dynamo. Theoretically, during its kinematic stage,…
Scaling of the Hosking integral in decaying magnetically-dominated turbulence
Hongzhe Zhou, Ramkishor Sharma, Axel Brandenburg
The Saffman helicity invariant of Hosking and Schekochihin (2021, PRX 11, 041005), which we here call the Hosking integral, has emerged as an important quantity that may govern the…
Low frequency tail of gravitational wave spectra from hydromagnetic turbulence
Ramkishor Sharma, Axel Brandenburg
Hydrodynamic and magnetohydrodynamic turbulence in the early Universe can drive gravitational waves (GWs) and imprint their spectrum onto that of GWs, which might still be observab…
