Event horizon telescope simul7/31/2023 ![]() “This incredible set of observations includes many of the world’s best telescopes,” said co-author Juan Carlos Algaba of the University of Malaya in Kuala Lumpur, Malaysia. The observations were concentrated from the end of March to the middle of April 2017 The data were collected by a team of 760 scientists and engineers from nearly 200 institutions in 32 countries or regions, using observatories funded by agencies and institutions around the globe. “There are multiple groups revving up to see if their models are a match for these rich observations, and we’re excited to see the whole community use this public data set to help us better understand the deep links between black holes and their jets,” said co-author Daryl Haggard of McGill University in Montreal, Canada. ![]() The sequence finishes by showing what gamma ray telescopes on the ground, and Fermi in space, detect from this black hole and its jet.Įach telescope delivers different information about the behavior and impact of the 6.5-billion-solar-mass black hole at the center of M87, which is located about 55 million light-years from Earth. The screen splits to show how these images, which cover the same amount of the sky at the same time, compare to one another. Next, the view changes to telescopes that detect visible light (Hubble and Swift), ultraviolet light (Swift), and X-rays (Chandra and NuSTAR). (The scale for the width of squares is given in light-years in the bottom righthand corner). ![]() It then moves through images from other radio telescope arrays from around the globe, moving outward in the field of view during each step. The sequence begins with the EHT image of the black hole in M87 released in April 2019 (the data was obtained in April 2017). The video shows data across many factors of ten in scale, both of wavelengths of light and physical size. The NASA telescopes involved in this observing campaign included the Chandra X-ray Observatory, Hubble Space Telescope, Neil Gehrels Swift Observatory, the Nuclear Spectroscopic Telescope Array (NuSTAR), and the Fermi Gamma-ray Space Telescope.īeginning with the EHT’s now-iconic image of M87, a new video takes viewers on a journey through the data from each telescope.
