    Blazar Variability

    January 1, 2020, Categories  Astronomy/Space

    An artist’s conception of a blazar, a galay powered by an active nucleus. Blazars are the most common sources detected by NASA’s Fermi gamma-ray spacecraft. Astronomers have modeled the bright, variable emission from the blazar CTA102 between 2013-2017 using data taken from the gamma-ray to radio bands. They are able to explain the multiuwavelegnth variability observed using a geometrical model for the rapidly moving jets. Credit: M. Weiss/CfA

    Active galactic nuclei (AGN) are supermassive black holes at the centers of galaxies that are accreting material. These AGN emit jets of charged particles that move at speeds close to that of light, transporting huge amounts of energy away from the central black hole region and radiating across the electromagnetic spectrum...

    NASA’s WISE, Fermi missions reveal a surprising Blazar connection

    Black-hole-powered galaxies called blazars are the most common sources detected by NASA's Fermi Gamma-ray Space Telescope. As matter falls toward the supermassive black hole at the galaxy's center, some of it is accelerated outward at nearly the speed of light along jets pointed in opposite directions. When one of the jets happens to be aimed in the direction of Earth, as illustrated here, the galaxy appears especially bright and is classified as a blazar. Credit: M. Weiss/CfA

    Astronomers studying distant galaxies powered by monster black holes have uncovered an unexpected link between 2 very different wavelengths of the light they emit, the mid-infrared and gamma rays...
