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
DA 193 is a blazar [1] located in the constellation of Auriga. It has a high redshift of 2.365. [2] [3] It was first discovered as an unknown astronomical radio source in 1971 by D.G. MacDonell and A.H. Bridle. [4] This is a low polarized quasar [5] containing a classic homogeneous synchrotron self-absorption spectrum. [6]
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]
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 0458-020 is found variable across the electromagnetic spectrum and a source of gamma ray activity. [7] [8] [9] It is known to show optical flares which was detected by Fermi Gamma-ray Space Telescope (Fermi LAT) [10] and by the Nordic Optical Telescope in September 2012, where it was reported to be 30 times brighter than its daily flux of (E > 100 MeV) when recorded by Fermi LAT. [11]
PKS 0208-512 is a blazar [1] located in the southern constellation of Eridanus.It has a redshift of 1.003 [2] and was first discovered in 1975 by astronomers conducting the Parkes 2700 MHz survey in Australia as a bright astronomical radio source. [3]
