    3C 454.3 is a blazar (a type of quasar with a jet oriented toward Earth) located away from the galactic plane.It is one of the brightest gamma ray sources in the sky, [2] and is one of the most luminous astronomical object ever observed, with a maximum absolute magnitude of -31.4. [3]

    en.wikipedia.org/wiki/Magnetar

    A magnetar's 10 10 tesla field, by contrast, has an energy density of 4.0 × 10 25 J/m 3, with an E/c 2 mass density more than 10,000 times that of lead. The magnetic field of a magnetar would be lethal even at a distance of 1,000 km due to the strong magnetic field distorting the electron clouds of the subject's constituent atoms, rendering ...

    The first true quadruple quasar system was discovered in 2015 at a redshift z = 2.0412 and has an overall physical scale of about 200 kpc (roughly 650,000 light-years). [ 74 ] A multiple-image quasar is a quasar whose light undergoes gravitational lensing , resulting in double, triple or quadruple images of the same quasar.

  6. Blazar - Wikipedia

    en.wikipedia.org/wiki/Blazar

    A blazar is an active galactic nucleus (AGN) with a relativistic jet (a jet composed of ionized matter traveling at nearly the speed of light) directed very nearly towards an observer. Relativistic beaming of electromagnetic radiation from the jet makes blazars appear much brighter than they would be if the jet were pointed in a direction away ...

    Artist's impression of the optically violent variable quasar 3C 279. [1] An optically violent variable quasar (often abbreviated as OVV quasar) is a type of highly variable quasar. It is a subtype of blazar that consists of a few rare, bright radio galaxies, whose visible light output can change by 50% in a day. [2]

    3C 273 is a quasar located at the center of a giant elliptical galaxy in the constellation of Virgo. It was the first quasar ever to be identified and is the visually brightest quasar in the sky as seen from Earth, with an apparent visual magnitude of 12.9. [2] The derived distance to this object is 749 megaparsecs (2.4 billion light-years).
