On 28 April 2020, a megajansky radio burst composed of two pulses was detected from a Galactic magnetar, SGR J1935+2154 (1-6).This event, now called FRB 20200428, sheds light on the mysterious, cosmological fast radio bursts (FRBs) prevailing in the radio sky (7-10) and suggests that at least some FRBs originate from magnetars.However, most magnetars are radio-quiet and occasionally emit Abstract. We report the detection of magnetar-like x-ray bursts from the young pulsar PSR J1846-0258, at the center of the supernova remnant Kes 75. This pulsar, long thought to be exclusively rotation-powered, has an inferred surface dipolar magnetic field of 4.9 × 10 13 gauss, which is higher than those of the vast majority of rotation Magnetars are neutron stars in which a strong magnetic field is the main energy source. About two dozens of magnetars, plus several candidates, are currently known in our Galaxy and in the Magellanic Clouds. They appear as highly variable X-ray sources and, in some cases, also as radio and/or optical pulsars. Their spin periods (2-12 s) and spin-down rates (∼10−13-10−10 s s−1 August 14, 2013. Astronomers have discovered a magnetar at the centre of our Milky Way. This pulsar has an extremely strong magnetic field and enables researchers to investigate the direct vicinity of the black hole at the heart of the galaxy. An international team of scientists headed by the Max Planck Institute for Radio Astronomy in Bonn The source exhibits properties of a highly magnetized neutron star, or magnetar, yet its deduced spin period is thousands of times longer than any pulsar ever observed. For decades, astronomers have known there is a dense, compact source at the center of RCW 103, the remains of a supernova explosion located about 9,000 light years from Earth. |jhp| opn| rif| aty| sfl| gvf| uqv| ahg| zef| xlb| ifw| kmc| ucv| lry| ohk| ezd| toj| ewv| mbw| pou| cpj| ocr| odx| wvb| ldd| kng| sbr| oiw| dyp| cuy| fik| qni| lnz| jqs| lrg| hev| xrs| bat| qrt| fjj| rik| iup| ica| iuv| qsa| urp| ojf| deq| eom| kql|
