Electromagnetic counterparts of high-frequency gravitational waves having additional polarization states: distinguishing and probing tensor-mode, vector-mode and scalar-mode gravitons

Fang-Yu Li, Hao Wen, Zhen-Yun Fang +2

GWs from extra dimensions, very early universe, and some high-energy astrophysical process, might have at most six polarizations: plus- and cross-type (tensor-mode gravitons), x-,…

Kerr-Sen Black Hole as Accelerator for Spinning Particles

Jincheng An, Jun Peng, Yan Liu +1

It has been proved that arbitrarily high-energy collision between two particles can occur near the horizon of an extremal Kerr black hole as long as the energy and angular mome…

Excitation of high frequency voices from intermediate-mass-ratio inspirals with large eccentricity

Wen-Biao Han, Zhoujian Cao, Yi-Ming Hu

The coalescence of a stellar-mass compact object together with an intermediate-mass black hole, also known as intermediate-mass-ratio inspiral, is usually not expected to be a viab…
