Astronomers observed such a collision in 2017 using Dark Energy Camera on the Blanco Telescope in Chile, providing complementary data to the observation from LIGO.Īstronomers See Light Show Associated With Gravitational Waves Collisions between neutron stars produce a lot of light in the form of short duration gamma ray bursts in addition to gravitational waves. Performing follow-up observations of gravitational wave events, to confirm the nature of the source. Next-generation observatories like the Large Synoptic Survey Telescope (LSST) will provide a census of millions of galaxies from their gravitational distortions. Reconstructing the location of most of the mass in the universe using gravitational lensing. While they’re too faint to be seen directly, closer-by galaxies and clusters sometimes magnify their light, allowing us to learn about the ancestors of the Milky Way and other modern galaxies.ĭiscovering Distant Radio Galaxies via Gravitational Lensing Using gravitational lensing to search for the earliest galaxies in the universe. This image of the black hole at the center of the nearby galaxy M87 reveals how gravitation affects the matter in orbit and the light that material emits, providing a novel test of general relativity in a regime where gravity is very strong.ĬfA Plays Central Role In Capturing Landmark Black Hole Image Center for Astrophysics | Harvard & Smithsonian astrophysicists research the predictions of general relativity in many ways:Ĭapturing the first image of a supermassive black hole using the Event Horizon Telescope (EHT).
