A novel probe of graviton dispersion relations at nano-Hertz frequencies
Bill Atkins, Ameek Malhotra, Gianmassimo Tasinato
We generalise Phinney's 'practical theorem' to account for modified graviton dispersion relations motivated by certain cosmological scenarios. Focusing on specific examples, we sho…
Measuring kinematic anisotropies with pulsar timing arrays
N. M. Jiménez Cruz, Ameek Malhotra, Gianmassimo Tasinato +1
Recent Pulsar Timing Array (PTA) collaborations show strong evidence for a stochastic gravitational wave background (SGWB) with the characteristic Hellings-Downs inter-pulsar corre…
New universal property of cosmological gravitational wave anisotropies
Ameek Malhotra, Ema Dimastrogiovanni, Guillem Domènech +2
The anisotropies of the stochastic gravitational wave background, as produced in the early phases of cosmological evolution, can act as a key probe of the primordial universe parti…
