High-redshift JWST massive galaxies and the initial clustering of supermassive primordial black holes
Piao, Yun-Song; Huang, Hai-Long; Jiang, Jun-Qian
In this paper, we show that the initial clustering of supermassive primordial black holes (SMPBHs) beyond a Poisson distribution can efficiently enhance the matter power spectrum, and thus the halo mass function. As a result, the population of initially clustered SMPBHs with
Resonant conversion of gravitational waves in neutron star magnetospheres
McDonald, Jamie I.; Ellis, Sebastian A. R.
High-frequency gravitational waves are the subject of rapidly growing interest in the theoretical and experimental community. In this work we calculate the resonant conversion of gravitational waves into photons in the magnetospheres of neutron stars via the inverse Gertsenshtein mechanism. The resonance occurs in regions where the vacuum birefrin…
