Framework for describing perturbations to the cosmic microwave background from a gravitational wave burst with memory

Autor: D. R. Madison

Publikováno v: Physical Review D. 103

Gravitational wave bursts with memory (BWMs) can generate measurable, long-lived frequency shifts and permanent angular deflections in distant sources of light. These perturbations vary across the sky with a characteristic spatial pattern and evolve

Persistent Astrometric Deflections from Gravitational-Wave Memory

Autor: D. R. Madison

Publikováno v: Physical Review Letters. 125

Gravitational waves (GWs) produce small distortions in the observable distribution of stars in the sky. We describe the characteristic pattern of astrometric deflections created by a specific gravitational waveform called a burst with memory. Memory

The mergers of supermassive black hole binaries (SMBHBs) promise to be incredible sources of gravitational waves (GWs). While the oscillatory part of the merger gravitational waveform will be outside the frequency sensitivity range of pulsar timing a
