Astronomers using simulated data have produced a glimpse of the sky as it would appear in gravitational waves, cosmic ripples in space-time generated by orbiting objects. The image shows how space-based gravitational wave observatories expected to launch in the next decade will enhance our understanding of our galactic home.
Since 2015, ground-based observatories have detected about a hundred events representing the mergers of systems that pair stellar-mass black holes, neutron stars, or both.
Watch as gravitational waves from a simulated population of compact binary systems combine into a synthetic map of the entire sky. Such systems contain white dwarfs, neutron stars, or black holes in tight orbits. Maps like this using real data will be possible once space-based gravitational wave observatories become active in the next decade. Brighter spots indicate sources with stronger signals and lighter colors indicate those with higher frequencies.
Using data simulating the expected distribution and gravitational wave signals of these systems, the team developed a way to combine the data into an all-sky view of the galaxy's UCBs. A
