    4U 0142+61 is a magnetar at an approximate distance of 13 000 light-years from Earth, located in the constellation Cassiopeia. In an article published in Nature on April 6, 2006, Deepto Chakrabarty et al. of MIT revealed that a circumstellar disk was discovered around the pulsar. This may prove that pulsar planets are common around neutron ...

    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 0420-014 is a blazar [1] located in the constellation of Eridanus. This is a high polarized quasar [2] [3] with a redshift of (z) 0.915, [4] first discovered as an astronomical radio source by astronomers in 1975. [5] The radio spectrum of this source appears to be flat, making it a flat-spectrum radio quasar (FRSQ). [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 279 (also known as 4C–05.55, NRAO 413, and PKS 1253–05) is an optically violent variable quasar (OVV), which is known in the astronomical community for its variations in the visible, radio and X-ray bands. [2] The quasar was observed to have undergone a period of extreme activity from 1987 until 1991. [3]
