Adding electromagnetic birefringence to pulsar timing and astrometry to detect gravitational waves
Keisuke Inomata, Marc Kamionkowski
It was recently shown that the time variation of the polarization of electromagnetic waves from pulsars can be used, in cross-correlation with pulsar timing, to probe the chirality…

Note on pulsar timing array correlation functions induced by peculiar velocities
Neha Anil Kumar, Keisuke Inomata, Marc Kamionkowski
Several papers have recently calculated the contribution to pulsar timing array overlap reduction functions (ORFs) induced by our peculiar velocity with respect to the rest frame o…

Gravitational Waves from Particles Produced from Bubble Collisions in First-Order Phase Transitions
Keisuke Inomata, Marc Kamionkowski, Kentaro Kasai +1
We discuss a new source of gravitational waves (GWs) from first-order phase transitions. The collisions of bubbles of the new phase can efficiently produce particles that couple to…
