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 ...
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]
RX J1131-1231 is the name of the complex, quasar, host galaxy and lensing galaxy, together. The quasar's host galaxy is also lensed into a Chwolson ring about the lensing galaxy. The four images of the quasar are embedded in the ring image. Cloverleaf: 4 [3] Brightest known high-redshift source of CO emission [4] QSO B1359+154: 6
The longest period pulsar, at 118.2 seconds, as well as one of the only known two white dwarf pulsars, AR Scorpii. [68] The first white dwarf pulsar AE Aquarii. [69] [70] The pulsar with the most stable period, PSR J0437−4715; The first millisecond pulsar with 2 stellar mass companions, PSR J0337+1715; PSR J1841−0500, stopped pulsing for ...
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 ...
PKS 1127-145 is a radio-loud quasar [1] located in the constellation of Crater. This is a Gigahertz Peaked Spectrum object [2] [3] with a redshift of (z) 1.187, [4] first discovered by astronomers in 1966. [5] Its radio spectrum appears to be flat making it a flat-spectrum radio quasar, or an FRSQ in short. [6] [7]
PKS 0537-286 (referred to QSO 0537-286), also known as QSO B0537-286, is a quasar located in the constellation Columba. With a redshift of 3.104, the object is located 11.4 billion light years away [1] and belongs to the flat spectrum radio quasar blazar subclass (FSQR). [2] It is one of the most luminous known high-redshift quasars. [3]
3C 345 has been known to fluctuate in brightness. For example, it brightened from magnitude 17.2 to 16.0 between 10 April 2018 and 8 May 2018 when observed in R band. [7] A bright GeV gamma-ray flare was observed by the Fermi Gamma-ray Space Telescope on 31 May 2017, as the flux increased by 40 times above average. [8]
